Staff Report

The growth of wildfires in the West could double the amount of sediment moving through the region’s rivers, U.S. Geological researchers found in a new study. Increased sediments can affect both water quality and the amount of water available for communities.

In nearly nine-tenths of the watersheds, sedimentation is projected to increase by more than 10 percent.
