SUMMARY:Lecture: The Story of the Salton Sea - FULL
DESCRIPTION:THIS PROGRAM IS FULL. \nSpeaker: Dave Blanchet\, (ret.) Hydrologist \nFirst there was the geology\, and then came the flood.  The Salton Sea is located along the San Andreas Fault\, and it is geology that repeatedly created and drained a vast natural lake over millions of years\, called Lake Cahuilla\, in what is now the Imperial Valley. Starting in the 20th century\, agriculture began to flourish in California’s Imperial Valley\, and diversion canals were dug to divert water from the Colorado River into the dry desert.  But the wild nature of the Colorado River soon took the upper hand. Events went horribly awry as record-breaking floodwaters destroyed the manmade dams and canals\, and the full flow of the Colorado River flowed unabated into the Salton Trough for two years. Only through immense effort was the flooding finally stopped\, and the Colorado River returned to its course\, flowing into the Sea of Cortez.  Tonight’s speaker\, Dave Blanchet\, is a retired hydrologist from Anchorage\, Alaska\, and a lifetime member of ABDNHA.  General Public: $12\, Members: $10\, Volunteers: $8. Please register at www.abdnha.org or at the Nature Center\, 760-767-3098.
