A three-dimensional groundwater flow model (MODFLOW-NWT) of the Columbia Plateau Regional aquifer (CPRAS) in Washington, Oregon, and Idaho was developed to provide an integrated understanding of the hydrologic system to implement effective water-resource management strategies. The U.S. Geological Survey (USGS) Groundwater Resources Program assessed the groundwater availability as part of a national study of regional systems (https://pubs.usgs.gov/circ/1323/). The CPRAS assessment includes the status of groundwater resources, how these resources have changed over time, and development and application of tools to estimate system responses to stresses from future uses and climate variability and change. A major product...
This release contains data collected to study the impacts of vegetation removal on the condition of Lake Ozette Sockeye spawning habitat. From October 2018 to May 2019, continuous sediment temperature and subsurface dissolved oxygen were collected at sites near Olsen's Beach on the eastern shore of Lake Ozette, WA. Data were collected from 3 sites; a spawning control (SC) where sockeye currently return to spawn; a vegetation control (VC) where nearshore vegetation inhibits the amount of sockeye spawning; and a vegetation treatment (TR) area where nearshore vegetation was manually removed to assess if habitat quality can be improved. In addition to the continuous data, particle size data from the nearshore were determined...

This data release provides information on the chemistry and character of bed sediments accumulated in the 1.6-mile long impoundment behind Enloe Dam on the Similkameen River in Okanogan County, WA. Sediment samples were collected during four weeks in October – December 2019. The sampling locations were distributed among 10 transects that ranged from 0.1-0.2 miles apart along the length of the reservoir. Surficial grab samples of bed material were collected at 27 locations representing the left, right or center of the channel cross-section where sampling was possible using a Ponar sampler. Sediment cores were collected with a Vibracore at 12 locations at or near the surficial grab sample transects, and discrete sediment...

A three-dimensional groundwater flow model, constructed in MODFLOW-NWT, was developed to evaluate the groundwater flow system near Puget Sound, Pierce and King Counties, Washington. A steady-state model version was constructed to simulate equilibrium conditions, while a transient model version was constructed to simulate monthly variability from January 2005 to December 2015. The model was used to simulate several hydrologic scenarios. This data release contains the input and output files for the simulations described in the associated model documentation report (https://doi.org/10.3133/sir20XXXXXX).
A three-dimensional groundwater flow model was developed in 1997 to evaluate the groundwater flow system at Puget Sound Naval Shipyard, Naval Base Kitsap, Bremerton, Washington (https://pubs.er.usgs.gov/publication/wri964147). In 2016, a regional groundwater flow model for the greater Kitsap Peninsula was developed (https://pubs.er.usgs.gov/publication/sir20165052). Using information from the 2016 regional model, the 1997 groundwater flow model for the Puget Sound Naval Shipyard was updated with a new interpretation of the underlying hydrogeologic units, a refined model grid, and improved recharge estimates. A steady-state model version was constructed in MODFLOW-NWT to simulate equilibrium conditions. MODPATH forward...
Measures used to assess trends in the 10th, 50th, and 90th quantiles of annual peak streamflow from 1916-2015 at 2,683 U.S. Geological Survey stations and within 191 4-digit HUCs in the conterminous United States. Linear quantile regression was applied to the selected quantiles of log-transformed annual peak streamflow to represent trends for a range of flood frequencies from small, common floods to large, infrequent floods. Comparative trends in pairs of quantiles were characterized as coherent, convergent, or divergent by comparing the slopes of linear quantile regression equations.
These data present chemistry and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern U.S. as one component of a larger USGS study in the summer of 2013. This data presents a selected suite of chemistry collected at these sites (PAHs, Organochlorines, PCBs, Trace Elements, and current use pesticides) used in calculating a Probable Effect Concentration-Likely Effect Benchmark quotient mixture score for contaminants measured in sediments. The toxicity data presents results of toxicity tests following ASTM and US EPA standard methods for sediment toxicity tests with the amphipod Hyalella azteca (28-d exposure), the midge Chironomus dilutus (10-d),...
This data release provides source code and an R workspace with functions comprising a non-linear baseflow separation model, calibrated values of parameters and estimates of the baseflow component of daily streamflow at selected streamflow gages. Parameter values were determined by calibration of the model. Estimates of the baseflow component include daily values and the total baseflow as a fraction of streamflow for the analysis period. The file 'run_bf_sep.zip' in the directory 'Nonlinear Baseflow Model Source Code, Functions, and Scripts" has a complete set of model functions, parameters for 13,208 USGS streamflow gages, and a script to run the model.

Site-specific parameters for a non-linear baseflow separation model determined by automated calibration to maximize baseflow. The file "bf_param_usgs.csv" has parameter values for 13,208 sites where USGS operated a streamflow gage and calculated daily streamflow for at least 300 days from water year 1981 to 2020. The file "bf_param_wa_ecy.csv" has parameter values for 41 sites where the Washington Department of Ecology operated a streamflow gage from water year 1991 to 2019. The parameters may need to be re-calibrated at a site for some applications.

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....

The depths to a high and average water table below the land surface were estimated across the Clover Creek watershed in Pierce County, Washington. Groundwater model simulations provided initial estimates of water-table depths for the analysis. To provide optimized, data-driven estimates of these depths, a continuous bias correction surface was applied to model output according to differences between simulated and observed water levels at observation wells.
This dataset includes spatial locations where surface water presence observations were collected during the late summer baseflow period in Mt. Rainier National Park and surrounding area in Washington State, July 2018 - September 2020.
