Summary of Activity and Data Gathered: 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.
