This U.S. Geological Survey (USGS) data release contains Darcy flux and mass flux of per- and polyfluoroalkyl substances (PFAS) data measured using passive flux meters (PFMs) in monitoring wells at the Yakima Training Center (YTC) in Yakima, Washington. The measurements were conducted by the USGS in cooperation with the U.S. Army Environmental Command. This data release contains PFM data...

A ground-based magnetic survey was conducted in the southwest corner of Yakima Training Center, Washington, in 2025. Magnetic surveys are passive, non-contact, surface geophysical methods that measure the total ambient magnetic field. The magnetic survey utilized a Geometrics G-864 cesium magnetometer. Survey lines were carried out to better understand the subsurface along a prominent...

This data release documents estimates of groundwater recharge for the U.S. portion of the Salish Sea Basin in northwestern Washington. A U.S. Geological Survey Soil-Water-Balance (SWB) model (Westenbroek and others,2018) was developed for Hydrologic Unit Code 17110 to simulate the spatial distribution of net infiltration below the root zone on a daily time step from January 1, 1980...

The U.S. Geological Survey (USGS) National Water Quality Program, through the Prototyping Modeling and Assessment of Post-wildfire Water Availability project, aims to enhance the ability to assess and predict the impacts of wildfires on water supplies. Precipitation is a key driver of flooding, debris flows, and water quality responses following wildfire. The intensity, duration, and...

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 data were collected as part of the Stormwater Action Monitoring (SAM) program's Puget Small Streams (PSS) status and trends program. The data presented here were collected from 20 sites during water year 2022 for water temperature, air temperature, and sensor depth. Sensor depth was used as a surrogate for water depth and represents the arbitrary depth of water above the sensor...

This data release provides an archive of random forest regressions predicting streamflow correlation as a function of climatic similarity over the contiguous United States, based on streamflow information from water years 1981 to 2020. This data release also contains the underlying datasets used to generate those regressions and a series of scripts that facilitate their exploration and...

This dataset includes sediment temperature data collected from seven sites on the mainstem of the Quillayute River in the summer of 2024. Sediment temperatures were collected at up to four depths (1, 4, 7, and 11 centimeters) at each location using a temperature rod that was installed into the streambed. See "quillayute.sites.2024.csv" for field IDs, sediment thermal properties, and...

This dataset includes sediment temperature data collected from seven locations within the Big Soos creek basin from July 2023 to July 2024. Data collection took place at two locations on Covington Creek and Big Soos Creek, and single locations on Jenkins Creek, Little Soos Creek, and Soosette Creek. See "BigSoos.sites.csv" for field IDs, descriptions, and locations of these seven sites...

This data release contains information on four sediment cores that were collected by the U.S. Geological Survey in Conconully Reservoir, Okanogan County, Washington, in June 2022 and October 2023. Data include the location each sediment core was collected, descriptions of the sediment profile of two of the cores (i.e., texture, color, structure, and visible constituents), photographs of...

Backward particle tracking in groundwater was simulated with MODPATH and the MODFLOW groundwater flow model by Long and others (2024). Simulated particles were tracked backward from well intakes in areas within or near Joint Base Lewis-McChord (JBLM) for the purpose of determining their likely points of origin within groundwater recharge areas. Steady-state and transient simulations were...
