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.

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.

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...

Analysis of groundwater response to tidal fluctuations, Operable Unit 1, Naval Base Kitsap, Keyport, Washington

Chlorinated volatile organic compounds have affected groundwater beneath a former 9-acre landfill at Operable Unit 1 (OU 1) of Naval Base Kitsap (NBK) Keyport, in Keyport, Washington. The landfill was the primary disposal area for domestic and industrial waste generated by NBK Keyport from the 1930s through 1973. Naval Facilities Engineering...
