Data

Publicly Accessible

We are committed to providing data and information to the public.

Reliable

Our data are collected following rigorous quality control standards.

Unbiased

The USGS has a non-regulatory mission.

Long-standing

Our water monitoring network is over 100 years old in many parts of Washington State.

View our history

The USGS Washington Water Science Center currently operates over 380 data-collection sites in Washington.  The sites collect surface water, groundwater, water quality and meteorological data that are available in real time.  Current and historic data can be retrieved from the National Water Information System (NWIS) database and the National Water Dashboard.

Water Temperature Dynamics in the Quillayute River Basin, Washington, 2021 - 2023

The Quillayute River Basin in northwestern Washington consists of the Quillayute River and the river systems of its major tributaries, the Dickey, Sol Duc, and Bogachiel Rivers. With a drainage area of 629 square miles, the Quillayute River Basin provides important habitat for 23 distinct runs of anadromous steelhead and salmon, representing one of the largest and most productive watersheds on the

Channel Cross Sections of the Nooksack River near North Cedarville, WA, 2017-2021

This data release contains channel cross sections of the Nooksack River near North Cedarville, WA, collected during routine streamgaging and discharge measurement efforts at USGS streamgage 12210700. All cross sections were collected using an acoustic doppler current profiler (ADCP) from the downstream side of the Highway 542 bridge. Raw ADCP measurement data were processed using a combination of

Stream heat budget model input and scripts for simulating groundwater and thermal equilibrium controls on annual paired air-water temperature signal transport in headwater streams

We investigated the relative importance of groundwater (GW) and other local heat budget processes on downstream annual stream temperature signal characteristics using deterministic heat budget model (HFLUX) scenarios within an idealized stream reach representative of mountainous forested conditions. The purpose of this data release is to provide additional supplemental information for a published

High and average water table estimates for Clover Creek watershed, Pierce County, Washington

The depths to a high and average water table below the land surface were estimated across the Clover Creek watershed in Pierce County, Washington. Groundwater model simulations provided initial estimates of water-table depths for the analysis. To provide optimized, data-driven estimates of these depths, a continuous bias correction surface was applied to model output according to differences betwe

Identifying post-reservoir construction periods for monotonic trend analysis at streamgages in the United States

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 nati

MODFLOW-NWT model to simulate the groundwater flow system at Puget Sound Naval Shipyard, Naval Base Kitsap, Bremerton, Washington

A three-dimensional groundwater flow model was developed in 1997 to evaluate the groundwater flow system at Puget Sound Naval Shipyard, Naval Base Kitsap, Bremerton, Washington (https://pubs.er.usgs.gov/publication/wri964147). In 2016, a regional groundwater flow model for the greater Kitsap Peninsula was developed (https://pubs.er.usgs.gov/publication/sir20165052). Using information from the 2016

Water Temperature Mapping of the Skykomish, Snoqualmie, and Middle Fork Snoqualmie Rivers, Washington—Longitudinal Stream Temperature Profiles, Significant Thermal Features, and Airborne Thermal Infrared and RGB Imagery Mosaics

The Skykomish, Snoqualmie, and Middle Fork Snoqualmie River Basins have historically provided critical spawning, rearing, and core habitat for several salmonid species. These salmonid species include natural populations of Chinook salmon (O. tshawytscha), steelhead trout (O. mykiss), and bull trout (Salvelinus confluentus)—listed as “Threatened” under the Endangered Species Act—as well as coho sal

Temperature data collected from the Lower Yakima River from October 2018 to October 2020

A total of 27 temperature sensors were deployed along the lower 90 miles of the Yakima River at 7 locations where cold water had been previously observed. These 7 cold-water areas had 3 to 6 temperature sensors installed to document the extent and duration of these cold-water areas and their impacts on mainstem temperatures of the Lower Yakima River. Cold-water areas included the mouths of tributa
