State water officials are facing unprecedented challenges preventing erosion and runoff this winter after the Dixie Fire burned more acreage than any other single wildfire in California history. Crews have begun erosion control projects and are planning for the run-off of sediment into the Sierra watershed throughout the wet season. Crews with the California Conservation Corps are out doing erosion control in the burn scar areas in Greenville, in Plumas County. Most of the town was destroyed in the Dixie Fire.
