OPTIMIZATION OF LAKE POWELL TO SUSTAIN FLOW FOR BENTHIC INVERTEBRATES BELOW GLEN CANYON DAM

Hydropeaking is a phenomenon that causes daily variation in flow from hydropower dams. The hydropeaking at the Glen Canyon Dam has high range (difference of daily and and low) and has caused lowest diversity of the EPT population downstream the dam. We present a range of flows and corresponding volumes for different scenarios of discharge from the dam that are suitable to provide conditions to sustain the hydropeaking and increase the bug population.
