How an emerging wetland at the Salton Sea offers new hope for migratory birds and local communities.

The Salton Sea’s waterline continues to rapidly recede, leaving behind exposed playa that exacerbates respiratory diseases and other issues for nearby communities.
Unexpectedly, however, the shoreline’s recession has created an opportunity for nature to take its course, evident by the presence of newly emerging wetlands around the Salton Sea. There are roughly 6,000 acres of newly formed wetlands that have emerged around the Salton Sea. They are a product of agricultural outflows or from natural seeps from springs. In June of 2020, Audubon California released a report titled "Identifying Existing Areas for Habitat Protection/Enhancement and Dust Suppression Projects on the Salton Sea Exposed Playa" that assesses the amount and distribution of these wetlands.
Audubon California has received a grant from the United States Bureau of Reclamation that will fund project design, biological surveys, and community engagement for both dust suppression and the expansion, stabilization, restoration, and enhancement of 250 acres of these emerging wetlands near the town of Bombay Beach on the Salton Sea. These incidental wetlands can serve a dual purpose in creating vital habitat for migrating birds and mitigating the dust that endangers the respiratory health of the 650,000 people who live near the Salton Sea.
The existing Bombay Beach Wetland is located on the southeastern shore of the Salton Sea, about 3 miles east of the Bombay Beach community. It consists of a wetland and surrounding vegetation that has developed where several prominent washes converge and groundwater discharges. There are existing saline wetlands and brackish pond habitats for species including the Yuma Ridgway’s Rail, American Avocet, Northern Pintail, and possibly the Desert Pupfish.
The existing wetland will remain small, however, without restoration and stabilization. This is because the higher quality habitat area upslope is being increasingly dominated by a monoculture of the invasive Tamarisk plant. The wildlife species, however, are already using the area, despite the lack of formal restoration or management, indicating that there is an opportunity to enhance the area.
The Salton Sea as a whole is important for more than 300 species of resident and migratory birds. Additionally, where there is not wetland or vegetated habitats, there is bare playa that is responsible for dust pollution to the surrounding communities. It is imperative that these emerging wetlands at the Salton Sea be stabilized to ensure sufficient habitat along the Pacific Flyway and to mitigate dust pollution.
The Bombay Beach Wetlands project aims to stabilize and enhance various emergent and saline wetlands and playa habitats, protect human health by optimizing water use to promote dust suppression in nearby playas, and provide opportunities for recreational public access.
Wetland preservation and enhancement will be done by protecting existing vegetation, wetland, and aquatic habitat areas from damaging stormwater inflows with the reinforcement of shoreline berms that protect the area.
The reinforcement of berms, complemented by water-use optimization infrastructure, will allow for water to have a maximum environmental beneficial use. This project aims to optimize water use to irrigate vegetation around the adjacent playa for dust control, to maintain the salinity in wetland areas for optimal species productivity, and to enhance and promote new habitat in the wetland.
This project also aims to include outdoor recreation opportunities for the community and is receptive to public feedback on potential project design alternatives and public access ideas. We hope to make this emergent wetland an area that the public can experience, the birds can live in, and an area that can help mitigate public health issues.
The Bombay Beach Wetland Project is in the first phase, which is expected to take two years, which includes habitat and dust control project design, scientific monitoring and data collection, and community engagement in planning design. Following successful completion of this planning phase, groundbreaking on construction would start in 2023.
We are interested in getting public feedback and input on our project design and public access ideas. You can submit a public comment through our survey form here. Additionally, please join us for our second Community Advisory Meeting on Zoom to learn more about our project and share your ideas. We will announce this meeting on Facebook. The consultant for this project is Formation Environmental, LLC, with other groups pending as progress develops.

Funding for this project is being provided by the U.S Bureau of Reclamation. This project is being completed in cooperation with the Imperial Irrigation District and the California Department of Fish and Wildlife.
Coalition of conservation and community groups says groundbreaking is positive step towards ending years of inaction at California’s largest lake.

Audubon science finds that two-thirds of North American birds are at risk of extinction from climate change.
Clearly, the Desert Sun has had it with the state's inability to get projects moving at the Salton Sea:
This harkens to the years of “one more study is needed” that we’d wearily grown accustomed to as we witnessed the sea’s long decline, which shifted into overdrive with the end of Colorado River water inflows at the close of 2017.
Still, it is shocking to hear this type of refrain so shortly after the state finally stepped up with its plan to fulfill its commitment to sea restoration under the 2003 Quantification Settlement Agreement that has shifted the water that had been replenishing the sea to thirsty urban customers.
Get to work, folks. Promises were made and the state cannot let the now more-rapidly receding sea spiral into an ecological and environmental disaster which will have effects far beyond its own shores.

The California Water Resources Control Board yesterday heard a presentation from state officials on their progress toward meeting their goals for habitat restoration and dust control at the Salton Sea. According to an agreement completed late last year, the state must complete work on 500 acres by the end of the year, but there is little indication that it will reach even that modest goal.
Micheal Lynes, Audubon California's policy director, had this to say after the hearing:
"The deterioration of the Salton Sea continues, and the rate of progress on the Salton Sea Management Program (SSMP) is not keeping up with the rapidly changing conditions. We encourage the State Water Resources Control board to work closely with state officials to ensure that upcoming deadlines are met– including constructing 500 acres’ worth of projects at the sea by the end of 2018.”
Michael Cohen, senior associate at the Pacific Institute, added:
"While the state has taken some steps towards implementing the Salton Sea Management Program, the rate of the progress is not nearly enough to keep up with the sea's decline. It is imperative that the State Water Resources Control Board hold the state to its commitment to build habitat and dust control projects at the Salton Sea, this year.”
Terrific op-ed in Water Deeply from Allison Harvey Turner Allison Harvey Turner, of the S.D. Bechtel Jr. Foundation, and Barry Gold, of the Walton Family Foundation, about the State of California's recent progress addressing the environmental and public health crises at the Salton Sea:
"At the Salton Sea, the state has the opportunity to demonstrate its commitment to supporting human health, a resilient environment, a strong economy and a sustainable water strategy for Southern California. Now, promising plans on paper must turn into critical progress on the ground. We are closer than ever to solving the Salton Sea crisis. This is the time for diligence and dedication to make it happen."
Earlier this month, Audubon California led a group of chapter leaders to offer a firsthand look at the situation at the Salton Sea. We also co-hosted a community event to raise awareness about the developing environmental and public health crises.
