High Quality Content by WIKIPEDIA articles! Prehistoric Lake Cahuilla was an extensive freshwater lake that filled the Coachella, Imperial, and Mexicali valleys of southeastern California and northeastern Baja California during the centuries prior to Spanish entry into the region. The Salton Sea, which was accidentally created in 1905, is a much smaller analog of its prehistoric predecessor, Lake Cahuilla. Lake Cahuilla was created when the lower Colorado River shifted its course within its delta. Instead of flowing directly south to the head of the Gulf of California, the river's waters were diverted northwest into the Salton Basin, the base of which lay about 80 meters below sea level. Under climatic conditions similar to those of the early twentieth century, it would have taken about two decades of uninterrupted river flow to fill the basin to 12 meters above sea level. At that point, the lake would have overflowed to the south, feeding half of its waters through the Rio Hardyto the Gulf but losing the other half through evaporation. When the river shifted its course back to the south, the isolated basin would have taken more than five decades to completely dry out again.
