Green River in northeastern Utah has many access points. Below Flaming Gorge Dam, it is “one of the premier tailwater trout fisheries in the western United States.” DEQ’s recreational water quality monitoring checks for two health concerns: Harmful Algal Blooms (HABs) and Waterborne Pathogens (E. coli). Find the most recent monitoring information below.
