Since about 1935, upstream water diversions have reduced the amount of water that reaches the Colorado River’s delta in the northern Gulf of California. In most years, the river no longer reaches the sea.” While most of us are aware of the importance of the Colorado River to Arizona, we don’t always give much thought to what happens once the river passes us. Professor Karl Flessa and his students have been studying the Colorado River delta since 1992. For the past decade he has helped coordinate scientific monitoring of the effects of environmental flows to the Colorado River delta. This presentation explores the history of the Colorado River delta and the impact of work being done on restoring the delta.
Karl Flessa is Professor of Geosciences at the University of Arizona. He received his undergraduate degree from Lafayette College, a small liberal arts college in Pennsylvania, and his PhD from Brown University. He joined the University of Arizona faculty in 1977. His research interests include conservation biology, water policy and paleontology.
He coordinated scientific monitoring of the Cienega de Santa Clara during the 2010-2011 pilot run of the Yuma desalting plant. Another year he spent in Australia studying the Murray-Darling River system and Australia’s water policy. Since 2014 he has helped coordinate scientific monitoring of the effects of environmental flows to the Colorado River delta.
For fun, he enjoys travel, movies and racing his sports car.
