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

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

NEET Circular Data

The NEET Circular report summarizes findings on processes that influence nutrients and how nutrient enrichment can alter biological communities in agricultural streams. These findings are relevant to local, state, regional, and national decision-makers involved in efforts to (1) better understand the influence of nutrients on agricultural streams, (2) develop nutrient criteria for streams and rive

Data on Midwest stream diatom and stressors, 2013

The objective of this study was to assess the comparative influence of multiple stressors on benthic diatoms at 98 sites that spanned a range of stressors that occurred in an agricultural dominated region in the upper Midwest, USA. The primary stressors of interest included: nutrients, herbicides and fungicides, sediment, and streamflow; though the influence of physical habitat was incorporated in

Influence of urbanization on the health of juvenile salmonids in Pacific Northwest perennial streams

Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch),

Surface-Water for Washington

Real-time, daily, peak-flow, field measurements, and statistics of current and historical data that describe stream levels, streamflow (discharge), reservoir and lake levels, surface-water quality, and rainfall in Washington. Surface-water data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

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

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.
