1 BMPS FOR THE ATTOYAC BAYOU WATERSHED Lucas Gregory Texas Water Resources Institute [email protected] 979-845-7869 2 Best Management Practice Overview • Mostly NRCS approved practices from the NRCS Field Office Technical Guide • Focus on water quality and quantity improvements • Think about these and if you think they can be applied in the Attoyac Bayou watershed • Please fill out the BMP sheet with a or • Includes practices that promote: • reductions in adverse water quality from forestry • livestock habitat improvements and modifies use • wildlife habitat improvements and modifies use 3 FORESTRY BMPS 4 Forest Roads • Provides access with minimal • • • • impact Avoid steep slopes and try to follow the contour of the land when practical Cut trees along roads where sunlight is necessary to ensure drying of the road Water control structures should not divert water directly to streams Avoid SMZs, wet areas or sensitive locations 5 Streamside Management Zones (SMZs) • Creates a zone of stability • • • • around streams to increase water quality At least 50 feet wide on either side of streams Roads and skid trails that cross the SMZ should cross at a right angles and be kept to a minimum Log landings should be at least 50 feet from the edge of the SMZ Timber may be selectively harvested within the SMZ; don’t fall across the stream 6 Stream Crossings • Construct to minimize impact • Perpendicular to the stream • Appropriately size culverts and inspect for debris often • Never use dirt crossings • Remove temporary crossings ASAP 7 LIVESTOCK BMPS 8 Brush Management • Selective removal of brush • Mechanical, Chemical, Biological, Prescribed Burning • Increased vegetation growth • Better water quality NRCS Code (314) 9 Critical Area Planting NRCS Code (342) • Establishes permanent vegetation on erosion prone sites • Improves water quality • Provides additional forage and habitat 10 Fencing • Promotes better grazing distribution • Can be used to protect critical areas • Promotes improved water quality NRCS Code (382) 11 Filter Strips • Permanent buffer between cropland or grazing land and a water way • Reduces sediment, nutrient and pathogen pollution • Promotes improved water quality NRCS Code (393) 12 Grade Stabilization Structure • Helps control gully formation • Reduces sediment loss, nutrient and pathogen pollution • Promotes improved water quality NRCS Code (410) 13 Grassed Waterways • Natural or formed channel with permanent vegetation • Reduces erosion, nutrient loss and pathogen transport • Promotes improved water quality NRCS Code (412) 14 Grazing Land Mechanical Treatment • Promotes increased water infiltration and vegetation growth • Reduces runoff, and nonpoint source pollutant transport • Promotes improved water quality NRCS Code (548) 15 Heavy Use Area Protection NRCS Code (562) • Stabilization of areas frequently and intensively used by people, animals or vehicles • Reduces soil erosion and improves water quality • Improves livestock health 16 Nutrient Management NRCS Code (590) • Manage the timing and rates of nutrient application • Decreases nutrient pollution and input costs • Promotes improved water quality without decreasing production 17 Pipeline NRCS Code (516) • Redistribute the current water supply • Provide more watering locations for livestock and wildlife • Indirectly promotes improved water quality 18 Pond • Provides alternative water for livestock, wildlife and other uses • Captures runoff and traps sediment • Promotes improved water quality NRCS Code (378) 19 Prescribed Burning • Controls unwanted vegetation and promotes forage production • Promotes better grazing distribution • Promotes improved water quality thru increased forage production NRCS Code (338) 20 Prescribed Grazing NRCS Code (528) • Controlled vegetation usage • Improve forage quality through proper utilization • Promotes improved water quality through reduced erosion 21 Pumping Plant • Provides additional water for livestock and wildlife • Promotes better grazing distribution • Promotes improved water quality by encouraging livestock and wildlife to use areas away from the creek NRCS Code (533A, B, C) 22 Range / Pasture Planting • Provides abundant native or introduced forages for livestock and wildlife use • Promotes improved water quality NRCS Code (550/512) 23 Roof Runoff Structure • Collects and transports precipitation from a roof • Reduces runoff and erosion • Promotes improved water quality • Provides additional source of water for livestock and wildlife NRCS Code (558) 24 Shade Structures • Provides shade in areas that typically do not have it • Attracts animals away from riparian areas • Can be used in conjunction with water and supplement feeding • Promotes improved water quality 25 Soil Testing • Provides information on needed soil nutrients • Aids in preventing over application of nutrients • Promotes improved water quality • Keeps your pocket book healthier too! 26 Stream Crossing NRCS Code (578) • Provides a stream crossing with a hard bottom • Reduces streambed disturbance • Promotes improved water quality NRCS Photo 27 Supplemental Feeding Locations • Moves livestock away from the creek • Reduces time spent near creek • Promotes improved water quality 28 Water Well • Provides additional source of water • Aids in relocating livestock and wildlife away from the creek • Promotes improved water quality NRCS Code (642) 29 Watering Facility • Provides water for livestock and wildlife away from the creek • When paired with shade, this creates a natural loafing area • Reduces creek pollution by decreasing the amount of time animals spend there • Promotes improved water quality NRCS Code (614) 30 WILDLIFE HABITAT BMPS 31 Conservation Cover / CRP Land • Permanent NRCS Code (327) vegetative cover • Reduces soil erosion • Improves water quality Fort Hood Rangeland Re-vegetation Project 32 Early Succession Habitat Development • Manage early colonizing plants to benefit wildlife • Increases native plant diversity • Improves habitat • Improves water quality • Good native grazing NRCS Code (647) Fort Hood Rangeland Re-vegetation Project 33 Restoration and Management of Declining Habitats • Restore or conserve rare or declining vegetative communities • Protects native plant communities • Promotes improved wildlife habitat NRCS Code (643) 34 Riparian Forest Buffer • Reduces nonpoint source pollution transport and prevents floodplain erosion • Provides shade and plant material for improved creek habitat • Provides wildlife habitat and corridors NRCS Code (391) 35 Riparian Herbaceous Cover NRCS Code (390) • Reduces nonpoint source pollutant transport and erosion • Stabilizes stream banks • Promotes improved water quality 36 Upland Wildlife Habitat Management NRCS Code (645) • Manage upland habitat for wildlife uses • Increases food and cover for wildlife • Healthy ground cover promotes improved water quality 37 Vegetative Barrier • Permanent stand of stiff, dense vegetation • Situated across flow paths to reduce erosion • Promotes improved water quality NRCS Code (601) 38 Wetland Wildlife Habitat Management • Retain, develop or enhance wetland habitat for wildlife • Provides critical habitat • Promotes improved water quality thru the wetlands’ natural filtering ability NRCS Code (644) 39 Wildlife Watering Facility • Non-structured water facility • Expands suitable habitat for wildlife • Promotes improved water quality by reducing their time near the creek NRCS Code (648) 40 HUMAN SOURCE BMPS 41 Hunting Camp Septic System • Ensure that hunting camps are equipped with a minimal septic system • Prevent direct septage disposal to a waterway • Improves water quality 42 Septic System Maintenance/Upgrade www.pumper.com • Evaluate current system for proper functioning • Perform routine maintenance • Replace system if needed • Promotes improved water quality http://oceanworld.tamu.edu 43 Questions? http://attoyac.tamu.edu/ Lucas Gregory [email protected] 979-845-7869
