Three separate SWATHPlus surveys were conducted in Whiskeytown Lake in December 2018, May 2019, and September 2020 to measure possible debris flows into the lake during the 2018-2019 and 2019-2020 rainy seasons following the July-August 2018 Carr fire that burned vegetation around the entire lake. Post-fire hillslope sediment yields are commonly substantially greater than pre-fire yields, but the degree to which they increase can vary substantially. Effects of wildfire on sediment yield have important implications for hazards (debris-flow risk), ecosystem disturbance and recovery, and downstream water resources (storage capacity in lakes, as well as water quality). These data are intended for science researchers, students, policy makers, and the general public. These data can be used with geographic information systems or other software to identify bathymetric features. These data are not intended to be used for navigation.
