A shovel rests against a massive deposit of coarse sediment on the delta to Conconully Reservoir in Okanogan County, Washington. The sediment was deposited following the 2021 Muckamuck fire and a debris flow in July 2022. USGS scientists are studying the sediment and water quality in rivers and reservoirs impacted by the large fire.

Post-wildfire sedimentation and release of metals to Conconully Reservoir, Washington
The Issue: Wildfires can negatively impact reservoirs and water supply. On August 4th, 2021, a lightning strike started the Muckamuck fire in Okanagan County, Washington. The fire burned approximately 13,297 acres (~21 square miles) of forest and shrubland before it was contained. The burn engulfed a large portion of the area which drains into the Conconully Reservoir, a popular location for...
