Salton Sea

The Salton Sea is a big lake.

It sits in the hot desert of California. Long ago, the area was very dry.

Then, water from a river flowed in. This filled the dry land and made a lake.

Many people liked to visit the sea. They went there to swim and fish.

Birds also stop here to rest.

But the lake has problems now. The water has too much salt. This makes it hard for fish to live. When the water goes away, dust blows in the wind. People are working to help the lake and the birds.

The Salton Sea is a large, salty lake.

It sits in the desert of Southern California. The lake is in Riverside and Imperial counties. It lies on the San Andreas Fault.

This lake is different from most lakes. It has no way to let water out.

Long ago, this land was a dry desert. In 1905, water from the Colorado River flowed in. A flood broke a canal used for farms. This water filled the dry basin for two years. This made the modern Salton Sea.

In the 1950s, many people visited the sea. They stayed in hotels and went boating. Many birds also stopped here to rest. But the lake began to change. Farm water flows into the sea. This water has salt and other things in it. The desert heat makes the water even saltier.

Now, the lake is shrinking. When the water goes away, dust blows from the lake bed. This dust can be bad for people. People are working to fix these problems. They are building new ponds to help the birds.

It sits in Riverside and Imperial counties. The lake is located on the San Andreas Fault. It is part of a low area called the Salton Trough. This trough stretches all the way to the Gulf of California in Mexico.

The lake is shallow and has no way for water to flow out. A 2023 report says the surface area is about 318 square miles. It is a very unique place in the middle of the desert.\n\nThis modern lake was formed by a big accident in 1905.

People had dug a canal from the Colorado River to help farms. This water was meant to help plants grow in the Imperial Valley. However, heavy rain and snowmelt caused a flood. The water broke through a part of the canal called a head-gate. For two years, the Colorado River flowed straight into the dry desert basin.

The Salton Sea is a shallow, landlocked, and highly saline endorheic lake.

An endorheic lake is a body of water that has no outlet to the sea. This lake sits within Riverside and Imperial counties in Southern California. It is located on the San Andreas Fault inside the Salton Trough. This trough stretches toward the Gulf of California in Mexico.

A 2023 report measured its surface area at 318 square miles. The lake is a unique feature in a desert landscape.

To understand the lake, one must look at the history of the Colorado River. Over millions of years, the river's delta expanded and cut off the northern Gulf of California. The river has historically alternated between filling the basin and leaving it dry. When the river flowed into the basin, it created a freshwater lake. One such lake was Lake Cahuilla, also known as the Blake Sea. This ancient lake was six times larger than the modern Salton Sea.

Archaeological sites show Native Americans lived near these shores for thousands of years.

The modern Salton Sea formed due to a massive engineering accident in 1905.

In 1900, the California Development Company began digging irrigation canals. These canals were meant to bring Colorado River water to the Imperial Valley. In 1905, heavy rain and snowmelt caused the river to swell. This flood broke through a canal head-gate. The water diverted into the dry Salton Basin through the New and Alamo rivers. For two years, the river flowed into the basin until the breach was closed in 1907.

During the early 20th century, the lake remained full due to agricultural runoff. Farmers used large amounts of Colorado River water for irrigation. Much of this excess water flowed back into the lake. By the 1950s and 1960s, the area became a popular resort destination.

Communities grew with hotels, yacht clubs, and vacation homes. At its peak, more than 1.5 million people visited the area annually. The wetlands also became a vital stop on the Pacific Flyway for migratory birds.

However, the lake began to face a catastrophic decline in the late 20th century. Scientists warned in the 1970s that the lake would become inhospitable. The lake is fed by runoff from about 500,000 acres of farmland. This runoff contains salts, selenium, and fertilizers like nitrates. As the water evaporates in the desert heat, the salt concentration increases.

This high salinity caused massive die-offs of fish species. When the fish died, the bird populations that relied on them also declined.

In recent decades, the lake has faced new environmental challenges. After 1999, the lake began to shrink as farmers used water more efficiently. As the water recedes, it exposes the lake bed. The wind then carries clouds of toxic dust into nearby communities.

This dust contains salts and other materials from the dried bed. Local, state, and federal efforts to manage the dust have seen minimal success. The situation remains a serious concern for air quality in the region.

Efforts are currently underway to restore parts of this ecosystem. In 2017, the state developed the Salton Sea Management Program. The Torres Martinez Desert Cahuilla Indians partnered with the state to restore wetlands in 2018.

In 2021, construction began on the Species Conservation Habitat project. This project focuses on the delta of the New River. In 2025, water began flowing into the first complex of shallow ponds. These projects aim to manage dust and support wildlife in a changing environment.
