This is your direct link to all kinds of water resource information. Here you'll find information on Washington's rivers and streams. You'll also find information about groundwater, water quality, and many other topics. The USGS operates the most extensive satellite network of stream-gaging stations in the state, many of which form the backbone of flood-warning systems.

A Spatially Continuous Model of Annual Streamflow Permanence Throughout the Pacific Northwest
An interdisciplinary team comprised of USGS and university scientists has developed the Probability of Streamflow Permanence Model or PROSPER which predicts flow permanence for unregulated and minimally impaired streams in the Pacific Northwest.
New USGS Study Tracks Millions of Tons of Rocks, Gravel and Silt Carried by the Sauk River
TACOMA, Wash. — The U.S. Geological Survey recently published the results of a new five-year suspended-sediment and water temperature study from the Sauk River. The purpose of this study is to improve understanding of the magnitude and timing of suspended sediment from the Sauk River and its tributaries to the Skagit River.
New USGS Field Method is a Breakthrough for Contaminant Analysis in Water Samples
The U.S. Geological Survey published a new report highlighting a portable continuous-flow centrifuge which aims to save time and money on contaminant analysis of particles suspended in water samples.

Naturally occurring uranium in groundwater in northeastern Washington State
Uranium is a radioactive element (radionuclide) that occurs naturally in rock, soil, and water, usually in low concentrations. Radionuclides are unstable atoms with excess energy and as radionuclides decay, they emit radiation. The uranium decay sequence also includes other radionuclides of concern such as radium and radon. This fact sheet...

A conceptual framework for the identification and characterization of lacustrine spawning habitats for native lake charr Salvelinus namaycush
Lake charr Salvelinus namaycush are endemic to the formerly glaciated regions of North America and spawn primarily in lakes, unlike most other Salmoninae. Spawning habitats for lake charr are thought to be characterized by relatively large substrate particle sizes which provide sufficient interstitial spaces for egg incubation, but...

Jewel Cave National Monument and Wind Cave National Park in South Dakota contain two of the six longest caves worldwide. These caves contain subterranean lakes that are important points of intersection between the water table of the Madison aquifer and the caves. During 2015 to 2017, several subterranean lakes were discovered in Jewel Cave, which...
