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.

Groundwater and Tidal Time Series Data, Operable Unit 2, Area 8, Naval Base Kitsap, Keyport, Washington

This Data release includes time series data collected at Operable Unit 2, Area 8, at Naval Base Kitsap, Keyport, WA. Groundwater elevations and water quality parameters in five monitoring wells, along with tide levels in Port Orchard Bay, were monitored every 15 minutes during a 3-week duration. Time series data were collected from October 24, 2017, to November 16, 2017, a period that included nea

MODFLOW-NWT model used to simulate groundwater storage changes in the Quincy Basin, Washington

A three-dimensional, groundwater flow model (MODFLOW-NWT) was developed to examine groundwater storage changes in the Quincy Basin, Washington. The model was calibrated to conditions from 1920 to 2013. The model was used to (1) determine the change in groundwater storage from 1920 to 2013 , and (2) simulate the potential effects of increases in pumping.

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.
