Bathymetry of the Similkameen River above Enloe Dam near Oroville, Washington This data release provides the results of the bathymetric survey of the Similkameen River directly above Enloe Dam which took place over three days in late September 2020. The bathymetric survey was completed to enable an instrument-based estimate of the volume of legacy sediment impounded behind Enloe Dam. A shoreline water level survey collected points at the river’s edge using Trimble R8 GNSS Receivers. Safety requirements directly upstream of the dam made a ground survey infeasible, thus shoreline points were inferred from the National Agricultural Imagery Program (NAIP) 2015 imagery corrected to Okanogan County lidar. The study area polygon was constructed from the shoreline points with a 0.5m buffer applied....

A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface water quantity, quality, and use. This data release contains Mann-Kendall monotonic trend analyses for 18 observed annual and monthly...

These rasters were calculated from continuous resistivity profiles (CRP) surveyed using a SuperSting R8 8-channel resistivity meter with a CRP streamer containing a 100-m long array of 11 electrodes was towed behind a boat spaced at 10 m. After collection, the raw CRP files were georeferenced to coordinates concurrently by a global positioning system. Output files were merged and linearized. This was converted to a data file compatible...

It is also improving understanding of the natural and human factors affecting the balance between supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface water quantity, quality, and use. To describe the long-term trends in the surface water quality component of water availability, data from the USGS and other Federal, State, and local agencies were accessed primarily...
