Drew E Eppehimer, PhD

Drew Eppehimer is a fish biologist with the USGS Southwest Biological Science Center's Grand Canyon Monitoring and Research Center in Flagstaff, AZ. His research examines the environmental drivers of fish populations in the Colorado River Basin. 

Drew's research interests broadly span aquatic ecology including fish and invertebrates in both lakes and rivers. His research examines coupled human-natural systems such as artificial and regulated river systems and currently focuses on how drought, water storage, and reservoir operations impact biological invasions in the Colorado River Basin. His models quantify invasion risk and inform smallmouth bass management efforts in the Grand Canyon.
