Investigating Climate Change Impacts on Upper Colorado River Fish Fauna


July 2010 - June 2015


Changing water temperatures resulting from global climate change are anticipated to have impacts on native fish populations. This project seeks to use historical and current field data and modeling to investigate the current and projected impacts of water temperature changes on the ichthyofauna of the Green River below Flaming Gorge Reservoir (Utah and Colorado). The Principal Investigator will lead a doctoral student in assembling existing data, collecting additional field data, and modeling to provide natural resource managers with one or more useful models for understanding how they may expect warming water temperatures will impact native and nonnative fishes of the Green River.
