Updating Temperature Criteria for Wyoming Surface Waters - DEQ


March 2014 - August 2017


The goal of this project is to provide recommendations to WDEQ for new aquatic life use tiers and temperature criteria. Specific objectives are to identify a sufficient number of aquatic life use tiers to protect the aquatic communities present in Wyoming's waters, identify thermal tolerances for species within each aquatic life use tier, and evaluate the newly-developed aquatic life use tiers against fish distribution data.
