Toddy Pond Watershed-Based Protection Plan
Toddy Pond Watershed-Based Protection Plan June 2013 Toddy Pond Watershed-Based Protection Plan June 2013 Prepared by: Megan Facciolo Hancock County Soil & Water Conservation District 1 Toddy Pond Watershed-Based Protection Plan June 2013 1. Background Information A. Document Purpose and Scope The purpose of this Watershed Based Plan, herein after referred to as the “plan”, is to lay out a strategy and schedule for NPS mitigation and water quality protection efforts for the Toddy Pond watershed over the next ten years (2013 to 2023). The Hancock County Soil and Water Conservation District (HCSWCD) prepared the plan with assistance and input from the Toddy Pond Association (TPA), Maine Department of Environmental Protection (MDEP) and United States Environmental Protection Agency (EPA). The plan was developed to satisfy national watershed planning guidelines provided by the EPA. EPA requires nineelement plans for impaired watersheds, but allows alternative plans in several cases including protection of high quality or unimpaired waters. MDEP accepts alternative plans for unimpaired lakes that have completed a recent watershed survey provided that the plans follow EPA and MDEP guidance and include minimum planning elements. Toddy Pond meets these eligibility criteria, and the plan was written to include the EPA and MDEP required planning elements (sections 2 through 6 in the plan cover EPA’s five elements for alternative watershed-based plans). Note: Information collected during the 2013 Toddy Pond Watershed Survey forms the basis for much of the plan. As such, the Toddy Pond Watershed Survey Report is attached to the plan in Appendix A. The Toddy Pond Watershed Survey Report, in and of itself, is a very valuable tool for the TPA, residents, municipal officials, and road commissioners to identify and fix existing sources of NPS pollution. B. Watershed Background Toddy Pond is a 2,408 acre lake located in the towns of Orland, Surry, Blue Hill, and Penobscot in the County of Hancock, Maine. It is an eight-mile long water body with three distinct sections, but only 1 true basin. The lake has a direct drainage area of 17.2 sq. mi. all within the towns listed above (See Attachment A). The lake has a maximum depth of 122 feet and a mean depth of 27 feet. All four of the towns have adopted Comprehensive Plans and Surry, Penobscot, and Blue Hill have all recently updated their Shoreland Zoning Ordinances. Toddy Pond is a popular recreation area with a very high profile boat launch located on Route 1 in Orland. Swimming, boating, and fishing are enjoyed by many residents who live on the pond and those that come to visit. The pond receives heavy fishing pressure both in the summer and winter. The central and southern basins provide habitat for warm water sport fish while the northern basin offers good habitat for coldwater species. The Maine Department of Inland Fisheries and Wildlife annually stocks Toddy Pond since 1989 with different types of fish including brown trout, landlocked salmon, brook trout, lake trout, and splake. The Maine Department of Inland Fisheries and Wildlife lists Toddy Pond as a good bass fishery and one of the few ponds that contains a viable population of wild togue. Also, alewives run up into the pond annually during their spring spawning migrations. The pond is home to several families of loons and bald eagles. According to the Maine Audubon Society Loon Count, there was an average of approximately 19 adult loons and 3-4 chicks yearly from 1983-2010. Residents also report seeing numerous osprey and bald eagles on the lake with at least one nesting family of bald eagles. The Maine Natural Areas Program has a section of the watershed listed as a special area of concern for inland waterfowl/wading bird habitat and deer wintering areas. There have also been documented reports of the rare Upland Sandpiper in the northeastern section of the watershed which is listed as a threatened species in Maine under the Maine Endangered 1 Toddy Pond Watershed-Based Protection Plan June 2013 Species Act. The Maine Department of Inland Fisheries and Wildlife lists the Toddy Pond watershed as a priority brook trout watershed. According to the “Summary Report of Conditions in Hancock County” (published in 2006), prepared by the Hancock County Planning Commission, from 1970-2000 the populations of the towns of Surry, Blue Hill, Penobscot, and Orland grew by an average of almost 82%. The projected population for 2006-2015 predicts these towns’ population to continue to grow by about 23%. This report also shows that from 2006-2015, the projected number of new homes that will be constructed in these towns will increase by over 28%. With this population and development increase, there is an obvious high potential for increased stress to the water quality of Toddy Pond. C. Summary of Prior Watershed Work Since 2003, watershed volunteers have been active in monitoring for invasive aquatic plants in Toddy Pond. In 2008 and 2009, they participated in E. coli. bacteria testing of 3 sites around the lake, and volunteers have been conducting water quality monitoring since 1990. In 1998, watershed residents formed the Toddy Pond Association (TPA). In the last few years this group has had a renewing of efforts by creating a website and revamping its association newsletter, that now goes out to all 350+ property owners around the lake, not just TPA members. The TPA includes project coordinators for roles including boat inspections, membership and mailings, plant patrol, and water testing. The TPA also has a Board of Directors with representatives from each of the three parts of the lake. The Toddy Pond Association now boasts over 100 members. The mission of the TPA is “We believe that we have a responsibility to protect Toddy Pond and its watershed so that we and future generations may enjoy its beauty and the recreational opportunities it provides.” In 2012, Toddy Pond Association Members and Watershed Residents worked with the Hancock County Soil and Water Conservation District to conduct a Watershed Survey of the entire Toddy Pond Watershed. The Toddy Pond Watershed Survey Report was created from these findings (see Appendix A). Funding for the Toddy Pond Watershed Survey project, in part, was provided by the U.S. Environmental Protection Agency under Section 604(B) of the Clean Water Act. The funding is administered by the Maine Department of Environmental Protection in partnership with EPA. 2. Identification of the Causes or Sources of the NPS Threat A. Water Quality Summary Water quality data has been collected by the Maine DEP and the Volunteer Lake Monitoring Program for Toddy Pond since 1977. The water quality of Toddy Pond is considered to be above average and the potential for nuisance algae blooms is low. However, recorded secchi readings from the last ten years show a decline of almost 2 meters in clarity. Toddy Pond has a flushing rate of only 0.60 flushes per year (the average flushing rate for Maine lakes is 1-1.5 flushes per year). The low flushing rate of Toddy Pond makes the lake more sensitive to changes in its nutrient loading because it gives nutrients a chance to settle to the bottom and be recycled within the water column. 2 Toddy Pond Watershed-Based Protection Plan June 2013 B. Watershed NPS Threats The greatest threat to water quality in Toddy Pond is polluted runoff. During and after storms, soil and nutrients like phosphorus and nitrogen wash into the lake from the surrounding landscape via ditches, streams and overland flow. Excessive nutrients in stormwater runoff is very detrimental to lakes like Toddy Pond. Phosphorus, a nutrient that is common on land, is a primary food for all plants, including algae. In natural conditions, the scarcity of phosphorus in a lake limits algae growth. However, when a lake receives extra phosphorus from the watershed, algae growth increases dramatically. Sometimes this growth causes choking algae blooms but more often it results in small negative changes in water quality that, over time, damage the ecology, aesthetics, and economy of lakes. Phosphorus is found attached to soil particles, and by documenting soil erosion in the watershed, we can gain an understanding of sources of phosphorus to the lake. Other sources of phosphorus may include agricultural runoff, fertilizers (on agricultural land and on residential lawn areas), and malfunctioning septic systems. The Toddy Pond Association partnered with the Hancock County Soil and Water Conservation District to conduct a Watershed Survey in 2012 to identify sources of phosphorus to Toddy Pond. The survey followed MDEP guidance described in A Citizen’s Guide to Lake NPS Watershed Surveys. In the summer of 2012, Conservation District staff and trained volunteers surveyed all developed portions of the watershed and documented soil erosion sites. Surveyors documented the location, nature and extent of each site’s erosion and runoff problems, recommended maintenance and pollution fixes, and rated the impacts to the lake and the cost to fix each of the sites. Survey findings were summarized in the Toddy Pond Watershed Survey Report (2013), which includes maps and a spreadsheet of NPS sites (Appendix A). While there is active agriculture and logging in the watershed, we did not find that these areas were contributing phosphorus and sediment runoff issues to Toddy Pond. Therefore, we focused on the more developed areas of the watershed because this was the area of high concern for sediment and phosphorus exports. In total, 147 erosion sites were identified in the watershed. There were 35 Road Sites and 112 Residential Sites documented during the survey. Each site was rated based on its impact to the lake, the technical level necessary to install fixes, and the estimated cost to fix the site: 3 Toddy Pond Watershed-Based Protection Plan June 2013 The highest number of sites were residential and can be broken down into the following categories: 3. Watershed Plan Goals and Objectives Overall Goal: The overall goal of this plan is to maintain or improve Class GPA water quality standards in Toddy Pond by reducing phosphorus and sediment loading to the lake. This will be achieved through the following actions over the coming ten year period (2013-2023): Reduce current sources of phosphorus loading by fixing 87 of the 147 sites identified in the watershed survey (27 road sites and 60 residential sites). This will be achieved by providing targeted outreach, technical assistance, and cost-sharing assistance to install conservation practices at NPS sites identified in the watershed survey. Prevent new sources of phosphorus loading by facilitating and demonstrating improved land use practices. This objective will be met by conducting outreach and providing technical assistance to residents, road associations, and municipal officials. Educate watershed residents on NPS pollution issues by developing an Education and Outreach Plan for the Toddy Pond Watershed. This document will help us identify outreach priorities by developing specific, measureable outreach objectives. Conduct ongoing assessment of lake and watershed conditions by maintaining and utilizing the NPS Site Tracker. Site Tracker is an excel spreadsheet that can be used to monitor sites identified in the watershed survey, to add new sites as they are discovered in the watershed, and to mark sites as completed if they are fixed. 4 Toddy Pond Watershed-Based Protection Plan June 2013 4. Schedule and Milestones to Guide Plan Implementation A. Action Plan and Schedule Action items, an estimated schedule, and milestones were developed to address existing NPS sites with the highest impact and phosphorus loading to Toddy Pond and to prevent new NPS problems. The number and types of sites targeted in the plan was based on local knowledge about potential funding sources, landowner cooperation and other considerations. The plan is designed to be implemented over a ten year period, and an estimated schedule is provided for each action (Table 1). Potential funding sources and key partners were also identified for each action (Table 2). Table 1 – Estimated Schedule 2013 – 2014 Set up the NPS Site Tracker for identified sites in the Toddy Pond Watershed Survey. 2014 – 2016 2013 – 2023 Apply for an EPA Section 319 Clean Water Act grant through MDEP (only 1 Phase is anticipated). Notify landowners about the completed Toddy Pond Watershed Survey Report. Conduct EPA 319 project (if funded) with targeted cost sharing and matching grants for high priority sites. Notify landowners about NPS sites on their properties. Toddy Pond Association continues to do water quality monitoring to check transparency readings. Toddy Pond Association conducts annual meetings, outreach, and raises funds for ongoing stewardship. Landowners fix NPS sites independently. Toddy Pond Association uses NPS Site Tracker to identify maintenance needs and prompt ongoing road maintenance. 5 Toddy Pond Watershed-Based Protection Plan June 2013 Potential Funding Sources Reduce current sources of phosphorus loading to the lake by addressing NPS sites identified in the watershed survey Self-funded BMP installations at NPS sites Residential Sites- Inadequate/No Buffer sites (20 sites) 2014-2019 Landowners Private, TPA Other Residential sites (10 sites) 2014-2019 Landowners Private, TPA State Road BMP installations (1 site) 2014-2016 MDOT MDOT Provide opportunity for cost sharing assistance to install BMPs at NPS sites Private Roads (25 sites) 2014-2023 Private EPA (319), Private Public Beach/Public Boat Launch (1 site) 2014-2016 Town EPA (319), Town, TPA Residential sites (30 sites) 2014-2016 Landowners EPA (319), Private Conduct outreach & technical assistance Ongoing HCSWCD, TPA HCSWCD, TPA Notify landowners with watershed survey sites 2014-2016 TPA TPA Prevent new sources of phosphorus loading to the lake Hold tours to highlight conservation practices 2014-2020 TPA EPA (319) Work with road associations and Towns to prompt ongoing road maintenance 2014-2023 HCSWCD, TPA Town, Private Educate watershed residents on NPS pollution issues Develop an Education and Outreach Plan 2014 HCSWCD EPA (319) Implement action items from the Education and Outreach Plan 2014-2023 HCSWCD, TPA EPA (319), TPA Conduct TPA annual meetings Ongoing TPA TPA Raise funds to support ongoing lake stewardship work Ongoing TPA Private, Town Conduct ongoing lake and watershed assessment Conduct lake water quality monitoring Ongoing TPA, MDEP TPA, Private Maintain and utilize NPS Site Tracker Ongoing TPA TPA Table 2 – Action Items and Milestones Schedule 6 Who Toddy Pond Watershed-Based Protection Plan June 2013 B. Plan Oversight and Partner Roles The Toddy Pond plan will be carried out by the Toddy Pond Association with support from the Hancock County Soil and Water Conservation District. Partners include the Hancock County Soil and Water Conservation District, MDEP, the Towns of Blue Hill, Orland, Penobscot, and Surry , MDOT, private road associations, and landowners. Toddy Pond Association (TPA) will conduct water quality monitoring (through the Volunteer Lake Monitoring Program), facilitate outreach activities, promote watershed stewardship through its website and newsletter, and raise funds for stewardship work. They will also utilize the NPS Site Tracker to identify new NPS sites and prompt ongoing maintenance. Hancock County Soil and Water Conservation District (HCSWCD) will support the TPA with Plan implementation, provide technical assistance, and will write and administer the proposed EPA Section 319 Clean Water Act grant. Maine Department of Transportation (MDOT), private road associations, and landowners will address NPS issues on their properties and conduct ongoing maintenance of BMPs. The Towns of Blue Hill, Orland, Penobscot, and Surry will work to address NPS problems and conduct regular maintenance on town road sites. Maine Department of Environmental Protection (DEP) will conduct water quality monitoring and technical assistance and provide the opportunity for financial assistance through the NPS Grants Program. Environmental Protection Agency (EPA) may provide CWA Section 319 funds and guidance. C. Plan Outputs and Milestones Organizational Outputs TPA utilizes and maintains the NPS Site Tracker HCSWCD applies for 319 grant Development of an Education and Outreach Plan for the Toddy Pond Watershed Contact made with all property owners and road associations with sites identified in the watershed survey NPS Mitigation Outputs Number of NPS sites fixed by voluntary landowner initiative Number of high and medium impact NPS sites fixed with cost-sharing assistance Number of technical assistance visits Estimated pollutant load reductions achieved by installed BMPs Water Quality Outcomes Toddy Pond continues to meet lake GPA standards set by MDEP Stable or improved trend for lake water clarity (secchi readings) 7 Toddy Pond Watershed-Based Protection Plan June 2013 5. Proposed Management Measures The Toddy Pond Watershed Survey Report (Appendix A) was developed in 2013 and lists all identified erosion sites in the watershed that are contributing sediment and phosphorus to the lake. Typical problems for the land uses identified in the watershed survey are described in the sections below. Recommendations follow guidelines found in MDEP publications including the Gravel Road Maintenance Manual, Conservation Practices for Homeowners fact sheet series, and Erosion and Sediment Control Manual. The recommended BMPs accomplish the plan goal of reducing phosphorus and sediment loading to the lake by stabilizing bare soil and erosion and diverting, infiltrating or filtering polluted runoff before it reaches the lake. In addition to structural BMPs recommended for each problem, public education and outreach efforts will also be needed to promote responsible stewardship and ongoing maintenance activities. The NPS Site Tracker will be used by the Toddy Pond Association on an ongoing basis to identify new problems and to prompt maintenance of sites fixed through the plan. A. Residential Sites The watershed survey identified 112 residential erosion sites. Of these, 95 sites were rated as having low impact, 11 having medium impact, and 6 having high impact to Toddy Pond. Common problems included inadequate or lack of vegetated buffers, shoreline/bank erosion, lake access/driveway erosion, new construction issues, and large areas of open soil. Based on the survey results, the most common BMPs will include: Installing or enhancing vegetated buffers Installing rain gardens Mulching or planting open areas Installing runoff diverters on driveways and lake access points Stabilizing shoreline/bank erosion with a combination of fabric and rip rap and plantings The plan aims to address 60 of the residential erosion problems identified in the watershed survey. These sites will be fixed by providing landowners with small matching grants for plants, erosion control mulch or other materials. Since many of the low impact sites are low cost and easy to fix, we believe that once a good example of appropriate fixes has been demonstrated, other homeowners will see the benefits and will independently fix their identified problems after recommended solutions are brought to their attention through targeted outreach and/or technical assistance visits. B. Private Roads The watershed survey identified 35 private road sites. There were 9 high impact, 20 medium impact and 6 low impact sites. Common problems included unstable culverts (inadequate size, not functioning, unstable inlets and outlets), ditch and shoulder erosion, and surface erosion. The most common BMPs recommended in the survey included: Installing new culverts and stabilizing the ends with stone Clean, reshape, and armor ditches with angular stone or vegetation Crown and reshape roads to allow for proper drainage Turnouts to push water away from the road and road edges 8 Toddy Pond Watershed-Based Protection Plan June 2013 The plan aims to address 25 private road sites. Sites will be addressed by providing cost-sharing funds to road associations. Targeted outreach and technical assistance will be provided to road associations associated with the remaining sites. Ongoing maintenance (e.g., grading, removing accumulated sediment from culvert inlets and outlets and turnouts) is critical to long term performance of these BMPs and prevention of new NPS problems. As a result, the plan calls for periodic inspections of implemented BMPs through the NPS Site Tracker. Follow up contact will be made by the Toddy Pond Association to road associations and landowners for any maintenance needs. C. State Road and Public Beach/Public Boat Launch There was only 1 public beach/public boat launch site and 1 state road site identified in the watershed survey. The State road site was listed as medium impact and the public beach/public boat launch site was also rated as medium impact. Both of these sites will be addressed in the plan. The State road site involves stabilization of the sides of a bridge that will be fixed independently by the Maine Department of Transportation (MDOT). The plan aims to notify MDOT about the problem and request that the recommendations be incorporated into the road maintenance schedule. The NPS Site Tracker can be used to prompt periodic inspections of the state road site and communication with MDOT about future maintenance needs. The public beach/public boat launch site will be addressed by providing cost sharing assistance and technical assistance to help the town with designing a vegetative buffer that allows for public access and protects the lake. D. Town Roads There were no issues/sites identified in the watershed survey on Town Roads. However, Town Roads should continually be monitored for any new erosion issues and be added to the Site Tracker database as necessary. 6. Pollutant Load Reductions Preliminary estimates of the top 15 NPS sites identified were already calculated during the Watershed Survey process (Appendix B). These estimates will be used to help prioritize projects in the watershed. Pollutant load reductions will be estimated and reported to DEP for any work funded by 319 grants using methods approved and recommended by the DEP and EPA. 7. Water Quality Results Monitoring The TPA will continue to annually monitor Toddy Pond twice a month from May through September for Secchi disk transparency, temperature, and dissolved oxygen. DEP also conducts baseline monitoring on Toddy Pond about every five years for transparency and other water quality parameters. Every two years, DEP evaluates transparency data to assess trends in water quality conditions of the lake. The results of the transparency readings (positive, negative or stable) and DEP’s assessment of the trends will assist in determining whether the plan meets its goal of having stable or improving water quality over time. 9 Toddy Pond Watershed-Based Protection Plan June 2013 Attachment A- Toddy Pond Watershed 10 Appendix A: Toddy Pond Watershed Survey Report Toddy Pond Watershed Survey 2013 Hancock County Soil & Water Conservation District Acknowledgments The Toddy Pond Watershed Survey was completed as part of a grant obtained by the Hancock County Soil & Water Conservation District from the Maine Department of Environmental Protection (DEP).

It is an eight-mile long water body with three distinct sections, but only 1 true basin. The lake has a direct drainage area of 17.2 sq. mi. all within the towns listed above. The lake has a maximum depth of 122 feet, a mean depth of 27 feet, and a flushing rate of only 0.60 flushes per year (the average flushing rate for Maine lakes is 1-1.5 flushes per year). The low flushing rate of Toddy Pond makes the lake more sensitive to changes in its nutrient loading because it gives nutrients a chance to settle to the bottom and be recycled within the water column. Toddy Pond Watershed Toddy Pond is a popular recreation area with a very high profile boat launch located on Route 1 in Orland. Swimming, boating, and fishing are enjoyed by many residents who live on the pond and those that come to visit. The pond receives heavy fishing pressure both in the summer and winter. The central and southern basins provide habitat for warm water sport fish while the northern basin offers good habitat for coldwater species. Since 1989, the Maine Department of Inland Fisheries and Wildlife has annually stocked Toddy Pond with different types of fish including brown trout, landlocked salmon, brook trout, atlantic salmon, lake trout, and splake. The Maine Department of Inland Fisheries and Wildlife lists Toddy Pond as a good bass fishery and Watershed: one of the few ponds All the land that surrounds that contains a viable a lake that drains or sheds population of wild togue. Also, alewives run up into the pond annually during their spring spawnits water into the lake ing migrations. through streams, ditches, directly over the ground surface, or through ground water. The pond is home to several families of loons and bald eagles. According to the Maine Audubon Society Loon Count, there was an average of approximately 19 adult loons and 3-4 chicks yearly from 1983-2010. Residents also report seeing numerous osprey and bald eagles on the lake with at least one nesting family of bald eagles. The Maine Natural Areas Program has a section of the watershed listed as a special area of concern for inland waterfowl/wading bird habitat and deer wintering areas.

The mission of the TPA is “We believe that we have a responsibility to protect Toddy Pond and its watershed so that we and future generations may enjoy its beauty and the recreational opportunities it provides.” Appendix A: Toddy Pond Watershed Survey Report- Page 3 What is Threatening Toddy Pond Water Quality? The greatest threat to water quality in Toddy Pond, which is the same for all Maine lakes, is polluted runoff. During and after storms, soil and nutrients like phosphorus and nitrogen wash into the lake from the surrounding landscape via ditches, streams and overland flow. In an undeveloped forested watershed, stormwater runoff is slowed and filtered by trees, shrubs and other vegetation. It then filters through the soil and soaks into the uneven forest floor. In a developed watershed, stormwater velocity increases on impervious surfaces like rooftops, compacted soil, gravel camp roads and pavement, and does not always receive the filtering treatment the forest once provided. The nutrients in stormwater runoff can be bad news for lakes. Phosphorus, a nutrient that is common on land, is a primary food for all plants, including algae. In natural conditions, the scarcity of phosphorus in a lake limits algae growth. However, when a lake receives extra phosphorus from the watershed, algae growth increases dramatically. Sometimes this growth causes choking algae blooms but more often it results in small, insidious changes in water quality that, over time, damage the ecology, aesthetics, and economy of lakes. Phosphorus is difficult to measure directly as it occurs in nonpoint source pollution. However, phosphorus is found attached to soil particles, and by documenting soil erosion in the watershed, we can gain an understanding of sources of phosphorus to the lake. Other sources of phosphorus may include agricultural runoff, fertilizers (on agricultural land and on residential lawn areas), and sewage. The Toddy Pond watershed is experiencing significant development pressure. Many summer camps have recently been converted to year-round residences and poorly built, inadequately maintained camp roads and driveways are getting more and more use. All of these factors point towards an increasing threat of NPS pollution entering Toddy Pond from developed areas in the watershed. It is extremely important to document these NPS issues and work towards correcting them before the water quality of Toddy Pond declines. Water quality data has been collected by the Maine DEP and the Volunteer Lake Monitoring Program for Toddy Pond since 1977. The water quality of Toddy Pond is considered to be above average and the potential for nuisance algae blooms is low. However, recorded secchi readings from the last ten years show a decline of almost 2 meters (approx. 6 feet) in water clarity. Appendix A: Toddy Pond Watershed Survey Report- Page 4 Purpose of the Watershed Survey The primary purpose of the watershed survey was to identify and prioritize existing sources of polluted runoff in the Toddy Pond watershed. However, of equal importance was to: Raise public awareness of the connection between land use and water quality Raise public awareness of the impact of polluted runoff Use the information gathered as one component of a long term lake protection strategy Define specific areas within the watershed that need improvement (for example, roadways that are conveying polluted runoff to the lake) Make general recommendations to landowners for fixing erosion problems on their properties Identify areas where lakefront buffers need to be installed or enhanced Local citizen participation was essential in completing the watershed survey and will continue to be necessary for ongoing protection efforts. Methods The Watershed Survey is a standard method of documenting soil erosion in lake watersheds in Maine. After specialized training in survey techniques and documentation, volunteers: Walk areas of the watershed that have been impacted by humans Look for eroding soil Determine if the eroding soil can be transported to the lake, a tributary stream, or a ditch Document the problem Suggest methods to remediate the problem Water quality experts from the Hancock County Soil and Water Conservation District reviewed and updated all of the volunteer data. Volunteers document erosion issues in the Toddy Pond watershed. Appendix A: Toddy Pond Watershed Survey Report- Page 5 Watershed Survey Findings Volunteers and technical staff documented 147 sites within the Toddy Pond Watershed that threaten the lake (see Appendix B for the full site list). Out of these 147 sites 35 sites were Road issues and 112 sites were classified as Residential issues. Open soil along the shoreline of Toddy Pond. Piles of gravel washed into a ditch along a private road. Appendix A: Toddy Pond Watershed Survey Report- Page 6 Impact to the Lake Watershed Survey Findings Sites are given an “Impact to the Lake” rating based on the amount of erosion, the proximity of that erosion to a ditch, stream, or the lake, and evidence that eroded soil is moving off site toward the water. Out of the 147 total sites, 101 were rated as Low Priority, 31 as Medium Priority, and 15 were rated as High Priority in terms of impact to Toddy Pond. The findings show that most of the documented sites in the watershed are low and medium impact sites. Because of these multiple sources, many sites will need to be addressed to make a significant impact on reducing erosion issues. An eroding ditch leading directly into a stream that empties into Toddy Pond. Appendix A: Toddy Pond Watershed Survey Report- Page 7 Watershed Survey Findings Technical Level to Install & Cost to Fix the Identified Sites Sites are also given ratings on the technical level required to install fixes and an estimate of how much it would cost to fix the identified sites. Out of the total 147 sites that were documented, 100 were designated as having a low level of expertise needed (meaning a homeowner or volunteer could install the fixes with little or no assistance), 39 a medium level of expertise (meaning a person with erosion control training could supervise fixes), and 8 were high priority (meaning the site would probably require an engineered design). For the cost to fix the site, a low rating is given if the project will be approximately $500 or less, a medium rating is given to sites with an approximate cost of $500-$2,500, and a high rating is given for projects costing greater than $2,500. Of the 147 total sites, 88 were rated low for cost of materials, 44 sites were rated medium, and 15 were rated as high. Looking at the information for the technical level needed to install fixes and the estimated cost, most sites can easily be fixed by homeowners, volunteers, or road associations with a relatively low cost. This is good news for trying to get a majority of sites fixed around the watershed to protect water quality. Appendix A: Toddy Pond Watershed Survey Report- Page 8 Road Findings 35 of the 147 sites were categorized as Road sites: 33– Private Road 1– State Road 1– Public Beach/Public Boat Launch Out of these 35 Road sites, 26 sites (74%) were low or medium priorities for their impacts to Toddy Pond. Some of the common problems identified were: Unstable culverts (inadequate size, not functioning, unstable inlets and outlets) Ditch and shoulder erosion Surface erosion Recommended solutions: Install new culverts and stabilize the ends with stone Clean, reshape, and armor ditches with angular stone or vegetation Crown and reshape roads to allow for proper drainage Appendix A: Toddy Pond Watershed Survey Report- Page 9 Residential Findings 112 of the 147 sites were found at Residential Sites. These sites can be broken down into the following categories: A large majority of the residential sites identified (including most of the sites in the “Inadequate/ No buffer” and “Large Areas of Open Soil” categories) can be fixed easily by a homeowner with relatively little cost. Recommended solutions for above categories: Install vegetated buffers Crown driveways Vegetate or mulch open areas Stabilize shorelines with fabric and rip rap Appendix A: Toddy Pond Watershed Survey Report- Page 10 Residential Findings 106 of the total 112 Residential Sites were rated as having a Low or Medium impact to Toddy Pond. 82 of the total 112 Residential Sites were observed to lack or have an inadequate vegetated buffer along the shoreline. The majority of these sites were documented at a medium or low impact level. However, because of the number of sites that were lacking an adequate buffer, the cumulative impacts could have a detrimental effect on Toddy Pond. What Makes a Good Buffer? Regular lawn grasses are not good buffer plants. First, they are relatively impervious— water will flow over the top of grasses, and not soak into the ground. Second, grasses do not fill in completely, and there is opportunity for bare soil patches to contribute sediment to runoff. Additionally, many people over-fertilize grasses, and the fertilizer that makes the grass green may do the same for your lake! It is important to note that buffers of shrubs and trees do a much more effective job than bare ground or grass at keeping stormwater pollution from entering the lake. The best buffer is one with five parts— trees, shrubs, understory, groundcover, and a “duff” layer of decomposing organic matter. Trees help break the erosive energy of falling raindrops, shrubs and an understory have extensive root systems to hold the soil, and a groundcover along with a duff layer will act as a sponge and filter the stormwater. Deep shrub and tree roots also help hold the shoreline in place. Buffers can be installed inexpensively. You can either stop mowing and raking to the water’s edge and let plants grow up naturally, or you can plant the area with native trees and shrubs. Before doing any planting along the shoreline, always first check with your local Code Enforcement Officer to determine if any permits are needed from the town or state. Appendix A: Toddy Pond Watershed Survey Report- Page 11 Residential Findings 106 out of 112 of the Residential Sites were found to have a low or medium level of technical knowledge needed to install the fixes and 106 of the Residential Sites also had a low or medium predicted cost to fix the identified site. Appendix A: Toddy Pond Watershed Survey Report- Page 12 Summary of Watershed Survey Findings By far the largest NPS problem found in the watershed is an inadequate vegetative buffer along the shoreline. Planting a buffer requires minimum knowledge and relatively small cost. Educational outreach for homeowners should focus on how a shoreline buffer can benefit the lake and their properties. The next largest issue in the watershed in terms of impact to water quality is private road issues including general maintenance problems (clogged ditches, surface erosion) and unstable culverts. Education for these issues should be given to road commissioners and road association members on how to properly maintain a road. Having a properly maintained road is not only good for the lake, but also for the people who use the road because there will be less wear and tear on vehicles, it enables easier access throughout the year, and allows easier access for emergency vehicles. Also, the Maine Department of Environmental Protection estimates that $1 spent on road maintenance saves $15 worth of repairs. So, road association members will also be saving money in the future, if they work to maintain their road today. Page 18 shows an aerial representation of the identified sites in the Watershed Survey. For a list of sites, please see Appendix B. Appendix A: Toddy Pond Watershed Survey Report- Page 13 Next Steps: Where Do We Go From Here? Repairing the problem sites identified in this survey will require efforts by individuals, road associations, and municipal officials. Individuals Prevent runoff from washing sediment into the lake. Detain runoff in depressions or divert flow to vegetated areas. Call the Hancock County SWCD (667-8663) or DEP (941-4570) for assistance. Minimize the amount of cleared land and road surfaces on your property. Stop mowing and raking, and let lawn and raked areas revert back to natural plants. Deep shrub and tree roots help hold the shoreline in place and prevent erosion. Avoid exposing bare soil. Seed and mulch bare areas. Call your Code Enforcement Officer before cutting vegetation within 250 feet of the shore. Maintain septic systems properly. Pump septic tanks (every 2 to 3 years for year round residences; 4-5 years if seasonal) and upgrade marginal systems. Road Associations (or private roads without associations) Minimize road runoff by doing regular, comprehensive maintenance. Form a road association if one does not already exist. Call the Hancock County SWCD (667-8663) for more information. Get a copy of “Camp Road Maintenance Manual – A Guide for Landowners.” This reference is invaluable for anyone managing a gravel road. Call the Maine DEP at 941-4570 to order a copy, or download a PDF at http://www.ellsworthme.org/soilandwater/publications.htm For more extensive problems, seek technical assistance. Contact the Hancock County SWCD (667-8663) or Maine DEP (941-4570) to request technical assistance. Municipal Officials Enforce shoreland zoning ordinances to insure full protection of Toddy Pond. Conduct regular maintenance on town roads to control erosion issues to set a good example for the private road associations. Participate in and support long term watershed management projects. Promote training for road crews, planning boards, and conservation commissions. Appendix A: Toddy Pond Watershed Survey Report- Page 14 Where Do I Get More Information?
