Conduct baseline bathymetric survey of Jenkinson Lake for change detection work in response to Caldor fire in northern California
Location
Northern CA
Summary
Swath mapping of Jenkinson Lake was conducted using the R/V San Lorenzo 2022-01-10 - 2022-01-12. Single-beam mapping was conducted in the shallow upper portion of the lake using the CEEscope echosounder on a rigid-hull inflatable boat 2022-01-11 - 2022-01-12. Average daily lake levels recorded by El Dorado Irrigation District were approximately 3,448 ft (98 ft level), 67% of full. Area of bathymetric data collection on the reservoir delta at Hazel Creek and Sly Park Creek overlapped considerably with the lateral extent of the topographic UAS surveys conducted on 2021-10-13 (FAN 2021-655-FA) and 2021-11-04 (FAN 2021-659-FA), during which the water surface elevation was lower.
