The Carr Fire ignited in northern California on July 23, 2018, and over the following six weeks burned almost 300,000 acres (approximately half on federal lands), resulting in a federal major-disaster declaration (DR-4382). Approximately 93 percent of the area within Whiskeytown National Recreation Area was burned extensively during the Carr Fire, including all of the landscape surrounding and draining into Whiskeytown Lake. Whiskeytown Lake, a federally managed reservoir, therefore acted as a sediment trap for material eroded from hillslopes and streambeds in the aftermath of the Carr Fire. The U.S. Geological Survey has measured topographic change associated with sediment deposition and erosion in and around Whiskeytown Lake after the Carr Fire in order to support calculations of post-fire sediment yield from the surrounding landscape. This data release includes bathymetric surveys of submerged areas of the reservoir and topographic surveys of subaerial regions around the reservoir margin. Data collection and analysis have been supported by funds through H.R. 2157, the Additional Supplemental Appropriations for Disaster Relief Act of 2019.

The Carr wildfire began on July 23, 2018, and burned almost 300,000 acres (approximately half on Federal lands) in northern California during the subsequent 6-week period. Over 97 percent of the area within Whiskeytown National Recreation Area, California, burned during the 2018 Carr wildfire, including the entire landscape that surrounds and drains into Whiskeytown Lake.
