Bombay Beach Wetland

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.

Site Details

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.

Project Goals

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.

Progress Updates

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 FacebookThe 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.

Asthma on the rise around the Salton Sea

It's not just birds that are being harmed by the changes at the Salton Sea. Asthma is becoming epidemic.

Bird populations crashing at the Salton Sea

Excellent reporting in the Desert Sun about how observers are starting to see dramatic declines in bird populations at the Salton Sea. Time is running out to fix things.

Frank Ruiz: The fate of birds and people at the Salton Sea are linked

In an opinion piece in the Desert Sun, Audubon California's Frank Ruiz notes that issues of public health and bird habitat at the Salton Sea are linked:

When people argue that we must choose between habitat for birds at the Salton Sea and efforts to control dust, I am reminded of my father and his coworkers, and their small bird in the cage (in the mines). At the Salton Sea, when we ensure that birds survive, we will also ensure that people can thrive as well.

State’s 10-Year Plan for Salton Sea is a big step forward

— Still more work to do to control dust and restore habitat on thousands of acres of exposed playa in the coming year.

Andrea Jones gives an update on the Salton Sea

This is going to be a make-or-break year for the Salton Sea, as state officials attempt to figure out how to deal with the effects of wtaer diversions expected to kick in beginning in 2018. This is expected to have major implications not only for bird habitat, but for the hundreds of thousands of people who live in the area. Andrea Jones recently visited the Salton Sea to talk about the current situation, and what Audubon California is doing to help. Learn more about our work at the Salton Sea.

Early draft of state Salton Sea management plan circulating

Buried in this mid-December article about negotiations to finalize a plan to avoid shortages at the Colorado River are early details of the much-awaited 10-year management plan for the Salton Sea. This is the plan that the state will eventually rely upon to protect bird habitat at the Salton Sea, and reduce dangerous dust pollution caused as the sea recedes. Anyway, here's what the article says about the plan:

"The document, which was obtained by The Desert Sun, summarizes the state’s proposals for a “smaller but sustainable lake” and lays out broad goals for building new wetlands along the lake’s receding shores to cover up stretches of exposed lake bottom and provide habitat for birds.

The document says an estimated 50,000 acres of “playa” will be left dry and exposed around the lake by 2028. The construction of “water backbone infrastructure” is to begin with ponds where water from the lake’s tributaries will be routed to create new wetlands. According to the 24-page document, which describes the Salton Sea Management Program, initial construction will start on exposed lakebed west of the mouth of the New River “to take advantage of existing permits.”

The draft says that in addition to building wetlands, the state also will use “waterless dust suppression” techniques in some areas. Those approaches can include using tractors to plow stretches of lakebed to create dust-catching furrows, or even laying down bales of hay on the exposed lake bottom as barriers to block windblown dust."

Audubon California has been deeply involved in the process of creating the state management plan, and will continue to advocate for sufficient habitat for birds and other wildlife. A recent report from Audubon California determined that the Salton Sea needs to provide about 58,000 acres of habitat to maintain the bird populations currently using the lake.
