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.

Surface Water

Colville River - Station #12409000 - Kim Cesal

Streamflow measurements are vital to understanding stream conditions. We monitor rivers & streams throughout Washington.

Streamflow Data

Water Quality

Washington Water Quality

Monitoring water quality is important for protecting human and ecosystem health. We monitor rivers, streams, and lakes around the state.

Water-Quality Data

Groundwater

Artesian Well

The USGS monitors groundwater levels throughout Washington. The data are used to determine sustainable pumping rates for irrigation and domestic supplies.

A Baseline Assessment of Contaminant Concentrations in Sediment and Biota in Proximity to Coal Transport Tracks in the Pacific Northwest (2014)

This dataset provides baseline concentrations (from 2014) of polycyclic aromatic hydrocarbon (PAH), other aromatic organic compounds, mercury (Hg), and trace metal concentrations in sediment and biota collected from two sites along an existing rail line used for coal transport in the Columbia River Gorge, Washington. For this study, aquatic surface sediments, aquatic insects, and juvenile fish wer

Groundwater data for Washington

Data from wells, springs, test holes, tunnels, drains, and excavations in Washington; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Washington Water Science Center

Water-quality data for Washington

Chemical, physical, and biological properties of water, sediment, and tissue samples from Washington. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.

Surficial sediment data on the North Fork Stillaguamish River and State Route 530 landslide near Oso, Washington

These tables document grain-size distributions of sediment collected as part of a study on the geomorphic impacts of the March 2014 State Route 530 Landslide near Oso, Washington. This includes samples of material from the landslide deposit itself, covering a range of distinct facies present in the landslide, and samples of sand and gravel at various locations along the North Fork Stillaguamish Ri

Concentration of nitrate and other water-quality constituents in groundwater from the water table beneath forage fields receiving seasonal applications of dairy manure, Whatcom County, Washington (2015)

Application of dairy manure to cropland is intended to provide nutrients for crop growth and improve soil quality, the goal being to match the rate of nutrient application to that rate of nutrient removal by the crop. Nitrate contamination of groundwater is widespread and persistent in the shallow surficial aquifer of northwestern Whatcom County where dairy farming and forage production is a prima

Bathymetric Data in the Green River near Tukwila, Washington

The U.S. Army Corps of Engineers scheduled repair on parts of an 850-ft long levee located along the Green River near S. 180th St. and Highway 181 downstream of Kent, WA. There is a Muckleshoot Indian Tribe Usual and Accustomed treaty area fishing site immediately downstream from the proposed bank work area and the Tribe is concerned that the levee rehabilitation project may cause changes to this

Water-use data for Washington

Water-use data is collected by area type (state, county, watershed, or aquifer) and source (such as rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1985. The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report withdrawals.

Geospatial database of sampled sites and watershed and riparian characteristics of Puget Sound lowland ecoregion streams sampled for the 2015 Stormwater Action Monitoring status and trends study

Stormwater Action Monitoring (SAM) is a collaborative monitoring program between western Washington municipal stormwater permittees, state and federal agencies. SAMs role is to use the results of regional monitoring and focused studies to inform policy decisions and identify effective strategies to improve stormwater management in the Puget Sound region. The SAM program includes status and trend

Accelerometer scour monitor data on the Cedar River, Washington, 2013 - 2014

Accelerometer scour monitors were deployed on the Cedar River, Washington from 2013 to 2014 as part of a study on the timing of streambed scour at 73 locations in salmon-spawning habitat. This data release contains data of the three-dimensional orientation recorded at 20- to 30-minute intervals for the 46 accelerometer monitors that were recovered in 2014. Each accelerometer scour monitor was comp
