California’s Salton Sea is a fertile oasis in the hostile desert of southeastern California, adopted by millions of birds migrating along the Pacific Flyway. As California’s largest lake, it stretches across almost 35 miles in a remote, below sea-level valley in the southeastern corner of the state. Current Salton Sea information is posted below.
The Sea faces a host of challenges, including a declining water supply, rising salinity, very high levels of nutrients that generate excessive algal growth and very low oxygen levels, and, to date, a glaring disconnect between the rate of change and the rate of efforts to address that change.
