However, the sea is shrinking. Lake levels have declined more than 11 feet in the last 20 years (2003 to 2023)2. Changes in climate and inflows to the Salton Sea have resulted in a hypersaline body of water. The changes to the freshwater supply have also affected its wetland ecosystems, which support wildlife. These changes have also impacted the valleys around the Sea and their towns, agriculture, and infrastructure. As a result, air, water, and wildlife managers depend on research to make informed decisions related to the Salton Sea watershed." }, { "@type": "TextObject", "text": "This study will provide the foundation for gathering hydrogeologic and water availability information for the Salton Sea watershed.

It was most recently formed in 1905 when the Colorado River broke through an irrigation canal and flowed uncontrolled into the Salton Sea watershed. The Salton Sea is a terminal lake (it has no outlets). It is also in transboundary watershed, with area in both the state of California and Mexico\u2019s Baja California.
