The Salton Sea - San Diego County Water Authority
Restoring California’s Water Supply Reliability The Salton Sea early 2016. The water agencies’ money also funded a feasibility study and financial plan being developed by the California Natural Resources Agency and the Salton Sea Authority that will set a path forward for the state to meet its restoration obligations. That study is expected to be completed in 2016. Forging a Path Forward From the signing of the QSA in 2003, the Water Authority has advocated for the state to meet both its mitigation and restoration obligations. Most recently, the Water Authority urged the creation of a task force that would oversee restoration efforts and be led by the Governor’s Office. Gov. Jerry Brown’s 2015 budget created a Salton Sea Task Force and set aside money to hire a leader of this effort. The creation of the state task force is an indication that the state, after years of stalled action on the sea, has begun to acknowledge its obligations under state law created by legislation passed in 2003. Led by the assistant secretary for Salton Sea policy, the task force also consists of representatives from the Natural Resources Agency, the California Environmental Protection Agency and related state departments. Meetings with stakeholders started in 2015. The Salton Sea There are other signs of progress at the state level. Legislation signed in October 2015 sets key milestones for the state to fulfill its restoration obligations. The legislation tasked the Natural Resources Agency with providing a list of “shovel ready” projects, which is critical to move restoration forward in a timely manner. The Salton Sea Task Force has called for the creation of up to 12,000 acres of wetlands and seashore restoration over the next five years, and for work to begin on an additional 25,000 acres of restoration by 2020. A science advisory committee is being established to ensure the work is guided by the best available science. Another hopeful sign at the sea was the passage of the statewide ballot measure Proposition 1 in 2014. It included $475 million for the Natural Resources Agency to provide financial support for a variety of state settlement obligations, including restoration of the Salton Sea. The Water Authority joined its QSA partners and other stakeholders in advocating for projects at the sea to receive as much of that funding as possible. The governor’s budget for fiscal year 2016-17 includes $80 million in Proposition 1 funding for Salton Sea projects that expand habitat and suppress dust at the sea. In Search of a Sustainable Future Restoring California’s Water Supply Reliability DIVERSIFICATION Enhancing Water Supply Reliability The Salton Sea is the largest lake in California, covering about 376 square miles of Imperial and Riverside counties. It is found in the Salton Basin, which from the earliest documented history has been periodically filled with water, most notably ancient Lake Cahuilla. In its current form, the Salton Sea was created by accident when a dike gave way and the Colorado River flooded the basin in 1905. Since then, the sea has been fed mainly by agricultural runoff in the New and Alamo rivers (which start in Mexico and flow through the Imperial Valley) and the Whitewater River in the Coachella Valley. Today, the Salton Sea provides habitat for a wide range of bird species, including migratory birds on the Pacific Flyway. In recent years, questions have surfaced about the potential impacts on the sea caused by the Quantification Settlement Agreement, a historic set of docuAF = acre-foot ments signed in 2003 One acre-foot is to reduce California’s approximately use of the Colorado 325,900 gallons, River to its annual enough to supply two single-family allotment of 4.4 milhouseholds of four lion acre-feet largely for a year. through water conservation-and-transfer agreements. The QSA provides the state with a means to manage its Colorado River supplies through a water conservation program funded largely by the San Diego County Water Authority. Related efforts by the Water Authority and its partnering agencies (Coachella Valley Water District and Imperial Irrigation District) to provide environmental funding under the QSA Joint Powers Authority are a critical component of the sea’s future. Through that ongoing effort, the JPA has mitigated the impacts of the water transfers Sustained Federal Action is Needed Mitigation & Restoration Projects Recent efforts by the State of California to develop the Salton Sea Management Program provides a path toward a smaller, but more sustainable, Salton Sea. As a primary landowner at the sea and an entity with a vested interest in the continued success of the QSA, the federal government should continue to support this effort and help pay for ongoing restoration initiatives. Recent progress includes: ■ In August 2016, the U.S. Department of the Interior and the California Department of Natural Resources signed a memorandum of understanding regarding coordination of activities to manage the Salton Sea. A federal investment of $30 million is the latest critical funding piece for near-term and mid-term projects. 4677 Overland Ave. San Diego, California 92123-1233 858.522.6700 Salton Sea Mitigation and Restoration Sites sdcwa.org QSA Mitigation Projects Current Restoration Projects @sdcwa Printed on recycled paper ■ In September 2016, the U.S. Senate approved S. 2848, the Water Resources Development Act (WRDA) of 2016. The bill maintains the current authorization of $30 million for the U.S. Army Corps of Engineers at the Salton Sea. It also changes the status of pilot projects from “temporary” to “permanent.” The Water Authority supports the Senate’s Salton Sea provision. ■ The U.S. House Committee on Transportation & Infrastructure also approved its version of WRDA, H.R. 5303, in September 2016. The full House is expected to vote on the bill soon after Election Day. A conference committee would then reconcile differences between the House and Senate bills. Several mitigation and restoration projects supported by the Water Authority are under way in the Salton Sea Basin. 4 October 2016 The San Diego County Water Authority sustains a $222 billion regional economy and the quality of life for 3.3 million residents through a multi-decade water supply diversification plan, major infrastructure investments and forward-thinking policies that promote fiscal and environmental responsibility. A public agency created in 1944, the Water Authority delivers wholesale water supplies to 24 retail water providers, including cities, special districts and a military base.

Attention has recently focused on fugitive dust that might be created at the sea as a result of the QSA. However, Imperial and eastern Riverside counties – by the nature of their desert environment – have been designated by the U.S. Environmental Protection Agency as areas of non-attainment for dust particles known as PM10. Windblown dust from the surrounding desert, dirt roads, off-roading activities and pollution from Mexico are all factors in the current non-attainment designation – not the QSA. Funding a Mitigation Program Mexico 10% of Total Inflows Salton Sea water levels are influenced by several sources, including agricultural runoff, inflows from Mexico, and a small amount of rainwater.

In 2016, evaporation from the sea is estimated to be greater than the inflows from all sources. from the start and set the stage for the state to make good on its commitment for a restoration program at the sea. Decades of Environmental Concerns The sea’s environmental issues pre-date the QSA by decades. As far back as the 1960s, the sea has been monitored for rising salinity and selenium levels, two hallmarks of an inland body of water with no outlets fed by nutrient-rich agricultural runoff. Long before the QSA, both state and federal authorities forecasted a troubled future for the Salton Sea. In particular, salinity was expected to eventually threaten fish habitat even without a reduction of inflows to the sea. Under those conditions, the State of California assumed responsibility for developing and implementing a “restoration” program for the sea, separate from “mitigating” the discrete impacts of the QSA water transfers. Another related environmental issue is that the sea’s shoreline is receding due to factors unrelated to the QSA, such as Mexico divert- 2 Recognizing the need for water conservation and for ensuring beneficial use of California’s Colorado River supplies, the State Water Resources Control Board adopted a Revised Water Rights Order in 2002 that allowed the nation’s largest agriculture-to-urban water transfer to move forward. As part of the QSA, the Water Authority receives up to 200,000 acre-feet annually in water conserved in the Imperial Valley as part of the Water Authority’s water supply reliability strategy. Fugitive Dust Drives Air Quality Problems Projected PM10 Sources in 2047 Imperial County doesn’t meet federal air quality standards for PM10. Even if no restoration is implemented at the sea by 2047, pollution from exposed playa would only account for a small amount of emissions and windblown dust would continue to drive air quality problems. The Salton Sea CVWD agreed to pay $67 million in nominal dollars as seed money to jumpstart a state restoration program. The Water Authority has fully paid its share of this funding. Fulfilling a Mitigation Promise The Water Authority has met all of its financial commitments since 2003 and is in compliance with all state and federal environmental obligations. Most of that funding has gone toward providing bucket-for-bucket mitigation The Water Authority has been delivering water to the Salton Sea for water to the Salton Sea from more than a decade to help maintain water levels and give the state time to formulate and fund a restoration plan. 2003 through 2017 to eliminate any impact of the water transfers In addition, Coachella Valley Water on the sea’s shoreline.
