The talk is the last in the fall series of monthly lectures on natural history at the Grand Canyon.
The series features Canyon experts who are artists, photographers, scientists, rangers and outdoorsmen.
Potochnik has been a Colorado River guide since 1973.
He helped get the 1992 Grand Canyon Protection Act passed and was an adviser to Interior Secretary Bruce Babbit on environmental and recreational issues in the Grand Canyon Colorado River eco-system.
He was appointed to the Glen Canyon Dam Adaptive Management Program in 1996 and has taught geology and environmental science at Yavapai College, Prescott College and Northern Arizona University.
Dr. Potochnik has written chapters about the development and history of the river in "Grand Canyon Geology" and "Colorado River: Origin and Evolution" (published by the Grand Canyon Association).
In the lecture, Dr. Potochnik will discuss such topics as the recent experimental water releases from the Glen Canyon Dam, the significance and impact of the drought on river drainage, the Colorado River Management Plan and the parameters of the Adaptive Management Program.
