Detailed Description

On a scorching day in June 2022, the summer Lake Powell reached its lowest water level in five decades, National Park Service staff caught baby smallmouth bass in the lower Colorado River. Fisheries managers knew that if they didn’t act fast, it was just a matter of time before the voracious invader decimated vulnerable native fish populations across Grand Canyon.

Learn about how USGS scientists work with the National Park Service, U.S. Fish and Wildlife Service, and Bureau of Reclamation to protect Grand Canyon ecosystems from invasive smallmouth bass. From modeling fish population growth to forecasting the effects of future dam operations, the USGS’s unbiased, high-quality science helps on-the-ground managers rise to new challenges brought on by climate change.
