They have documented the effects of upstream water diversions on the fauna of the river’s estuary and estimated flows necessary for their restoration. Flessa directed the NSF-supported Research Coordination Network: Colorado River Delta, the environmental monitoring program for the Ciénega de Santa Clara during the test run of the Yuma Desalting Plant, and is currently the co-Chief Scientist for the Minute 319 Monitoring Program for the Colorado River Delta. He was recently a Distinguished Visiting Scientist at Australia’s CSIRO, where he studied river management in the Murray-Darling Basin. He received his undergraduate degree at Lafayette College and his Ph.D. from Brown University. |
