Data

IMPORTANT NOTE: This dataset includes spatial locations where streamflow permanence observations (continuous flow and dry) were recorded and stored as part of the Pacific Crest Trail (PCT) water report (https://pctwater.com/) and subsequently processed to align with the FLOwPER (FLOw PERmanence) field survey available in Survey 123. Additional information to describe the field conditions...

Hydrophones have been proposed as a potential surrogate for bedload transport, operating on the principle that particle collisions generate sound that scales in intensity with transport rate (for example, Geay and others, 2017). To assess that potential, the U.S. Geological Survey (USGS) partnered with the Washington Department of Transportation (WSDOT) in 2019 to install hydrophones on...

Glacier Creek drains a 82 square kilometer watershed that includes multiple glaciers on the north flank of Mount Baker in Whatcom County, Washington. The Washington State Department of Transportation (WSDOT) maintains a bridge along Highway 542 over Glacier Creek near its confluence with the North Fork Nooksack River, where Glacier Creek has formed an alluvial fan. To assist in WSDOT...

This U.S. Geological Survey (USGS) data release provides high-resolution thermal infrared (TIR) and true-color red, green, blue (RGB) imagery mosaics, longitudinal stream-temperature profiles (LTPs), thermal points of interest (POIs), and river centerlines from airborne surveys of 47 river kilometers (29 river miles) of the Quillayute and Bogachiel Rivers, Washington. The TIR and RGB...

The upper Cedar River Municipal Watershed (CRMW) is managed by Seattle Public Utilities and provides habitat that sustains an isolated adfluvial population of Endangered Species Act-listed bull trout (Salvelinus confluentus). Bull trout spawning in the CRMW begins in early fall when the water surface elevation of Chester Morse Lake and the stream discharges in its major tributaries, the...

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...

This data release includes information on data from 72 streamflow or surface-water presence datasets in the Conterminous United States. It includes location, dataset, parent dataset or publication, site identification (if available), start year, end year, number of years, number of days, frequency of data collection, Strahler stream order, and headwater status.

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...
