Washington Water Science Center

Data and Tools

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 Database called the National Water Information System (NWIS). Many of the links below access this database.

Surface Water

Surface Water

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

Streamflow Data

Water Quality

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

Groundwater

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

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.

Water temperature and depth data for the lower Quinault River during summer baseflow, Washington, August 2016 and 2017

Water temperature and the availability of cold-water refugia are important parameters during summer baseflows when stream water temperatures are at their maximum. The U.S. Geological Survey measured near-streambed and surface water temperatures along the lower Quinault River, on the Olympic Peninsula, Washington between August 9-12, 2016, during summer baseflow conditions. The survey occurred...

Suspended sediment concentration and loads for the South Fork Nooksack River at Saxon Road, Washington, 2010-2016 water years

Suspended-sediment samples were collected by USGS and NIT at the USGS streamgage South Fork Nooksack River at Saxon Road (12210000) from July 2010 to February 2016 over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; <0.0625 mm) using...

Suspended sediment concentration and loads for the Nooksack River at North Cedarville, Washington, June 4, 2011 to September 30, 2016

Suspended-sediment samples were collected by USGS and NIT at the USGS streamgage Nooksack River at North Cedarville (12210700) from December 2010 to January 2017 over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; <0.0625 mm) using turbidity...

Suspended sediment concentration and loads for the Middle Fork Nooksack River near Deming, Washington, 2014-2017 water years

Turbidity was continuously monitored at the USGS streamgage Middle Fork Nooksack River near Deming (12208000) from November 2, 2013 to September 30, 2017. A DTS-12 turbidity sensor (Forest Technology Systems) at the streamgage measured turbidity at 15-minute intervals. Suspended-sediment samples were collected at the streamgage over a range of discharge and turbidity conditions. Regression...

Suspended sediment concentration and loads for the North Fork Nooksack River below Cascade Creek near Glacier, Washington, June 26, 2015 to October 31, 2016

Suspended-sediment samples were collected by NIT and USGS at the USGS streamgage North Fork Nooksack River below Cascade Creek near Glacier (12205000) from June 2015 to October 2016 over a range of discharge and turbidity conditions. Regression equations were developed to estimate the suspended-sediment concentration (SSC) and the concentration of fine suspended-sediment (fSSC; <0.0625...

Turbidity was continuously monitored at the USGS streamgage Nooksack River at Ferndale (12213100) from October 29, 2011 to September 30, 2017. A DTS-12 turbidity sensor (Forest Technology Systems) at the streamgage measured turbidity at 15-minute intervals. Suspended-sediment samples were collected at the streamgage over a range of discharge and turbidity conditions. Regression equations were...

Turbidity, Discharge, Suspended Sediment Concentration, Suspended Sediment Load in Duwamish River, Tukwila, Washington

The Green/Duwamish River transports watershed-derived sediment to the Lower Duwamish Waterway Superfund site near Seattle, Washington. Understanding the amount of sediment transported by the river is essential information to the bed sediment cleanup process. Turbidity, discharge, suspended-sediment concentration (SSC) and particle-size data were collected by the U.S. Geological Survey (USGS)...

Biological metrics used in a USGS National Water Quality Project assessing nutrients in agricultural streams

This dataset includes algal and invertebrate metrics used to assess water quality conditions in agricultural streams of the Midwest. Data was collected in wadable streams from 2003 to 2008. Data includes two benthic algal metrics (percent eutrophic taxa and observed taxa/expected taxa) and two benthic invertebrate metrics (EPT taxa and observed taxa/expected taxa).
