After wildfires, storms can convey sediment, ash, pollutants, and debris from hillslopes to surface water, leading to immediate and long-term impacts on water quality, reservoir storage, and water treatment costs. Water providers and land managers have a need to effectively plan for, prevent, and mitigate impacts on water supplies. The USGS Water Resources Mission Area, in collaboration with USGS Water Science Centers, is building capacity to accurately assess and predict water-quality impairment after wildfire. This presentation will describe general trends in the quantity and quality of water following wildfire, lessons learned the “hard way,” and recent advances in understanding the impacts of wildfire on water quality and quantity. We will also describe ongoing efforts to improve our understanding of post-wildfire water-quality drivers and processes across different hydro-ecoregions.
