USGS scientist measures bathymetry with a remotely controlled Q-boat on Conconully Reservoir, Washington

Detailed Description

USGS Hydrologic Technician Chaska Boucher operates a remotely controlled Q-boat on Conconully Reservoir in Okanogan County, Washington. A portion of the watershed burned in the 2021 Muckamuck wildfire and a debris flow occurred in 2022. The Q-boat measures the bathymetry of the reservoir, allowing scientists to compare the volume of sediment stored in the reservoir before and after these events. The USGS is assessing sediment and water quality in the Conconully Reservoir and surrounding streams to better understand wildfire impacts on reservoir storage, water quality, and ecosystem health.
