Water-quality reconnaissance of Owyhee Reservoir, eastern Oregon

Research hydrologist Tyler King of the U.S. Geological Survey's Hydrologic Remote Sensing Branch examines a water sample collected from Owyhee Reservoir in eastern Oregon, April 10, 2025. King and scientists from the U.S. Bureau of Reclamation conducted a water-quality reconnaissance of the reservoir and found a significant amount of what they suspect is post-wildfire debris in the reservoir along with cyanobacteria.
