Data

This data release summarizes suspended sediment monitoring results on the Chehalis (USGS 12031000), Satsop (USGS 12035000) and Wynoochee (USGS 12037400) Rivers between water years 2019 and 2022. Sediment monitoring was based on a combination of continuous turbidity records and discrete suspended-sediment concentration (SSC) measurements. Data and results for each monitoring station were combined i

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 nationa

This archive documents a Soil-Water Balance (SWB) model of the Puyallup and Chambers-Clover Basins in Pierce and King Counties, Washington. The SWB model used to estimate a water budget and recharge for input into a groundwater flow model of the Puyallup and Chamber-Clover Basins between January 2005 and December 2015.

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

On October 5-6, 2022, a combination of Acoustic Doppler Current Profiler (ADCP) and Global Navigation Satellite System (GNSS) surveying were used to collect bathymetric data of the Lummi Sea Pond near Bellingham, WA. Distributed XYZ points were interpolated to create a continuous bathymetric map of the sea pond. The final product is two-meter raster in NAD88 (2011) UTM 10N coordinates, with elevat

This data release contains spatially gridded geospatial data (rasters), R scripts, and supporting files to run Random Forest models to predict the probability of late summer surface flow in Mount Rainier and surrounding area in Washington State for 2018–20. Gridded geospatial data that describes the physical conditions of Mount Rainier National Park and surrounding area are used to refine the exis

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 su

Measurements of suspended-sediment concentration and particle-size distribution were made in selected rivers located in Washington and Virginia with an in-stream, particle-size analyzer that uses laser-diffraction methods to measure the concentration and size of suspended particles. Measurements were made in 11 rivers from 2018 to 2019 using the LIST-SL2, a second-generation streamlined sensor tha

The Nooksack River watershed comprises the majority of the Water Resources Inventory Area 1 (WRIA 1) located in Whatcom County in Washington State. From its headwaters in the northwestern Cascade Mountains, the Nooksack River drains approximately 809 square miles, comprising most of western Whatcom County, including agricultural areas and the developed lowlands surrounding the towns of Deming, Eve

This data release summarizes suspended sediment monitoring results on the Bogachiel (USGS 12042800) and Calawah (USGS 12043000) Rivers between water years 2019 and 2021, based on a combination of continuous turbidity monitoring and discrete suspended-sediment concentration (SSC) measurements. Data and results for each monitoring station were combined into zip files. Each zip file contains:   Summ

This Data Release provides spatial data to support analysis of land cover change and channel width change in the Bogachiel and Calawah River basins, Washington. This supports a larger analysis that quantifies suspended-sediment yields for the two basins for water years 1977-1978 and more recently, for water years 2019-2021. Collectively the study evaluates influences of hydrology, geology, fire, a

This Data Release provides supporting data to characterize and identify influences of streamflow permanence in headwater streams in the Huachuca Mountains, Arizona, U.S.A. Relative conductivity as a proxy for surface water presence was measured in headwater streams in the Huachuca Mountains from 2010-2014. These data are summarized as mean daily values. Geologic influences on the timing of surface
