Bathymetry of the Similkameen River Above Enloe Dam Near Oroville, Washington

Shoreline water level shoreline points collected were used as the zero-elevation point. Directly above the dam, the inferred zero elevation point was based on NAIP 2015 imagery corrected to Okanogan County lidar. Bathymetric points were collect using an acoustic doppler continuous profiler (ADCP). Grid cell values record the depth in meters from the water surface to the sediment. Bathymetry surface was interpolated to 3m resolution using Spline Interpolation with Barriers in ArcGIS Pro 2.5.0. Barrier was set using survey_area polygon.
