2020/2021 Meetings

The AEG Southern Nevada Chapter holds dinner meetings eight times per year.  Meetings are usually held on the second Tuesday of the month at the Embassy Suites Convention Center located at 3600 Paradise Road (just north of Twain/Sands) in Las Vegas, Nevada.  Each meeting features a presentation regarding a pertinent geological, environmental, or other relevant science-based issue.

Due to the COVID-19 Pandemic, the April Meeting will be a

webinar run by AEG National.  An email will be sent out

on how to register for the webinar.



April Meeting
Tuesday, April 13, 2021, 6:30 p.m. PDT
“Drought and Megadrought in the Colorado River Basin, the New Normal?” 

Eric Kuhn, Former General Manager of the Colorado River Water Conservation District


The Colorado River provides water for two countries and nine states, including five million acres of irrigated lands and 40 million people. The river is now fully used, except for a man-made flow event in 2014, not a drop of its water has reached the Gulf of Baja California in over two decades. The river system has always been prone to long and severe drought periods, but now with climate change, it is facing reduced flows and an uncertain future. The recent science and what will be needed to adapt to the impacts of climate change on the river will be discussed.


Eric Kuhn is the retired General Manager of the Colorado River Water Conservation District and co-author with John Fleck of "Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River", University of Arizona Press, 2019.

The Colorado River District is the largest and oldest of Colorado’s four conservation districts. It covers most of the Colorado River Basin within Colorado. Almost two thirds of the flow at Lee Ferry originates in or flows through the district. Eric started employment with the Colorado River District in 1981 as Assistant Secretary-Engineer. In 1996 he was appointed General Manager, a position he held until his retirement in 2018.

From 1994 through 2001, he served on the Colorado Water Conservation Board, representing the Colorado River mainstem. In 2005, Eric was appointed by Governor Owens as an at-large representative on the Colorado Inter-basin Compact Committee, a position he held until 2018. He served on the Engineering Advisory Committee of the Upper Colorado River Compact Commission from 1982 -2020. 

Prior to working for the Colorado River District, he served as an engineer officer aboard nuclear submarines in the U.S. Navy and worked as a nuclear start-up engineer for Bechtel Power Corp. Eric has a bachelor’s degree from the University of New Mexico and a master’s degree from Pepperdine University.

Eric and John’s book, "Science Be Dammed", is about Colorado River hydrology, what we knew, when we knew it, and how we used it to shape the over-allocation of the river under the 1922 compact, the other major provisions of the law-of-the-river, and the projects we have in place today.
