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....

This data release contains four data sets that support ongoing U.S. Geological Survey investigations, in cooperation with the U.S. Navy, at the Bremerton Naval Complex (BNC), Sinclair Inlet, Washington. Child item #1 includes reported concentrations of mercury isotopes in 28 samples of new (2018-19) or archived (2008-09) particulate samples from the BNC, surface sediment from Sinclair Inlet, or surface sediment from representative bays in Puget Sound. Child item #2 includes the output data and geospatial locations of the cable deployment from the georeferenced fiber-optic distributed temperature sensing (FO-DTS) survey along the Operable Unit A unwalled shoreline. Child Item #3 includes the georeferenced near-bed...
This data release contains 3-meter gridded rasters of depth to bedrock below bathymetric surface, the thickness of unconsolidated sediment, and the volume of unconsolidated sediment within a 2.6-km reach of the Similkameen River, Okanogan County, Washington, impounded by Enloe Dam. 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...

The Stormwater Action Monitoring (SAM) program is a cumulative and regional monitoring effort in the Puget Sound region of Washington State. Under the SAM program, the status and trends of water chemistry, sediment chemistry, habitat and biota in small streams and nearshore marine waters in the Puget Lowlands are monitored and documented. As part of recommendations to the program made in 2018, site selection in 2019 focused on small watersheds ranging in size from 2.5-50 km2 with varying amounts of urbanization. A master list of 19,970 possible sampling sites was digitally snapped to the National Hydrologic Dataset (NHD) high-resolution version flowlines (1:24000), and from this a set of characterized nested basins...
This data release consists of the initial well input data for the logistic regression model, the conceptual well data for logistic mapping, the logistic mapping output data, the logistic mapping output vulnerability and vulnerability difference rasters, and supporting geographic information system (GIS) files for the study titled "Index of Vulnerability for Elevated Nitrates in Groundwater in the Puget Sound, Washington."
This archive documents a Soil Water Balance (SWB) model of the The White River Basin, Washington and immediate surrounding environs. The SWB model is used to estimate surface processes of a water budget including precipitation, interception, evapotranspiration, surface runoff, etc. for the upper White River area from January 1999 - December 2020.
This archive documents a Soil Water Balance (SWB) model of the Naval Base at Keyport, Washington and immediate surrounding environs. The SWB model is used to estimate hydrological processes of a water budget including interception, evapotranspiration, surface runoff, etc.) for the Keyport area during January 1980 - December 2015.
Note: this data release is currently being revised and is temporarily unavailable The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand for water need by delivering routine assessments of water supply and demand and an 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. An understanding of the impacts of reservoirs on water availability is essential for this assessment....

A continuous resistivity profiling (CRP) survey was conducted in a 1.2-mile reach of the Similkameen River upstream of Enloe Dam in December 2021 in Washington State. The survey was performed to characterize the resistivity of the water column and subbottom materials using the CRP method. The survey consisted of eight longitudinal profiles roughly equivalent in length and conducted in the right, left and center of the channel. In this survey, a 100-m cable with 11 electrodes spaced 10 m apart and outfitted with floatation aids was towed behind a boat at speeds of 1-1.5 m/s and data were collected using the dipole-dipole array type. In this configuration, two electrodes nearest the boat transmitted electric current...
