Salton Sea Facts

(Some information courtesy of SaltonSea.ca.gov)


Fact 1

The Salton Sea is not an unnatural "accidental sea". This myth begins with the factual history of the Sea. Indeed, massive flooding in 1905 caused the Colorado River to break through an irrigation canal head works and flow freely into the Salton Basin for a year and a half. By the time the breach was closed, the present-day Salton Sea was created.

This, however, suggests that a static, dry, natural state exists in the basin. It does not. In tracing the Seas' origins, it is found that Indians made use of a massive Seas' bounty during the 1500's, leaving behind artifacts that recorded their practices. From 1824 to 1904, the Colorado River flows flooded the Salton Basin no fewer than eight times. Each time and countless times before, the Colorado River has meandered west and filled the Basin with fresh water. Water filled the Salton Basin numerous times in the past, supplied by the Colorado River. These inland seas have all been a 'natural' result of the Colorado River as is the present Salton Sea. Unable to control the Colorado River, man could not prevent another inland sea from forming.

As to its present state, drainage from 500,000 acres of farms in the neighboring Imperial and Coachella valley’s now sustains the Sea. The Sea is a designated federal repository of agricultural runoff, and agriculture is a billion dollar mainstay of the Valley's economies. Decreased flow into the sea, however, makes its future questionable.


Fact 2

The Sea is one of the most important wetlands along the Pacific Flyway, and is increasingly so as over 97 percent of the inland wetlands that provided habitat value to the birds along the Pacific Flyway in California have disappeared.

The image here (courtesy of the University of Redlands) shows areas of the North American continent where birds tagged at the Salton Sea have been spotted.

Bird Migration

Several million birds migrate and inhabit the area every year. The Sea provides a wintering habitat to over 450,000 ducks and up to 30,000 snow and Ross geese. In fact, over 400 species of birds have been spotted at the Salton Sea National Wildlife Refuge, more than any other place in the U.S., other than the Gulf Coast of Texas. Endangered species also make the Sea their home, including the brown pelican and the Yuma clapper rail. In the past, when the old seas of the Salton Basin dried up, the Colorado River Delta provided the critical wetlands for the migrating birds, but now, since the Colorado River no longer has a delta in Mexico the Salton Sea is their last hope.


Fact 3

Before 1985, the Sea's State Park had more visitor days per year than did Yosemite National Park, and press reports from the 1960's highlight the popularity of the Sea as a recreational destination.

A 1985 California Department of Fish and Game study found that the Sea was more productive (fish caught per angler hour) than any California marine fishery and equal to the most productive freshwater fisheries. In 1989, the Department found the annual direct impact of the fishery to the local economy to be 50 to 65 million dollars. A study now underway indicates that the fishery may be the most productive in the world. Some estimates put the number of Tilapia in the Salton Sea at as many as 200 million. That's a lot of fish!

The Sea and the agriculture industry provide mutual economic benefit. The Sea itself could not exist without its primary water source-inflow from irrigation runoff, and the agriculture industry relies on the Sea for a repository of this runoff. Today, the annual agricultural economy of Riverside and Imperial counties combined is $1.5 billion.

Business and academic interests have suggested that a restored Sea could drive the regional economy for years to come.


Fact 4

The water is clean.

The State Water Resources Control Board tests the Sea twice a year and has not found pesticides at a significant level in the Sea. Pesticide levels are periodically found to be high at some drains, but the Sea's sheer volume and most pesticides' ability to biodegrade seem to limit their impact.

This was further validated with two independent studies conducted by the Salton Sea Science Subcommittee. This research indicated there were no pesticides in the sediment and water of the Salton Sea. A third study found extremely low levels of contaminants in the Sea's barnacles, a finding which surprised the researchers, because the levels were much lower than found in the waters of San Diego.

Selenium is a naturally occurring element in Colorado River water, the source of the vast majority of the Sea's water. Selenium is found at elevated levels in some inflows to the Sea and in the sediments of the deepest parts of the Sea. Yet in water taken from the Sea itself, selenium was found at only about 1 microgram per liter and the federal standards allow up to 5 micrograms per liter. The water at the Salton Sea is clean and many of the local residents and tourists frequently swim in what they refer to as "the healing waters" of the Salton Sea.


Fact 5

One of the sea's problems is its immensity and another is its complexity; it is California's largest inland body of water and supports a complicated and priceless ecosystem. Still another problem is its location. Far from urban centers and the usually vigilant eye of environmental interests, the Sea has been largely ignored. The environmental community is waking to the Sea's problems and possibilities (the Audubon Society has made the Sea a number one priority).

There is much more to learn about the Sea. One major factor has and continues to contribute to the Sea's downward spiral of ecological and economic health: salinity. The Sea's salinity has increased steadily over the years. Now at 44 parts per thousand, or at a content level 25 percent greater than the ocean, the hypersaline environment is jeopardizing the survival of fish and will ultimately jeopardize the survival of much of the Sea's biological bounty including the birds and surrounding wildlife.

The time for action is now, when there is still time to develop short term and, ultimately, long term solutions for restoring the Sea. Myths must be dispelled, myths and misperceptions that have contributed to public confusion for so many years.

The Sea's immensity, complexity, and remoteness may, in the past, have combined to create the Sea's greatest threat: uncertainty leading to unease, leading to inaction.

However, the knowledge gained from the extensive research on the real problems, coupled with political will to take responsible action, will go far in debunking the myths and making the restoration of the Sea a reality.

But the action we need is NOW. If we don't do something soon, the sea could be dead in as little as ten years.

 

Salton Sea SRA

The SDIA works wth the Salton Sea State Recreation Area and Picacho State Recreation Area by providing educational and interpretive activities for the public.

California State Park

Help support the park by planning a visit. There are many great outdoor activities available. Go fishing or hiking, bicycling or off-roading, your desert adventure awaits!

Contact SDIA for more information

Several campgrounds in the area offer a wide range of camping experiences. There are full hookups, tent sites and primitive beach sites available.
