Data

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

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.

Lithologic classifications of river gravels in the Sauk River watershed

The rock type, or lithology, of river gravels provides information about the bedrock source area of that material, and can act as a tracer to help assess relative gravel contributions from tributaries or distinct valley deposits. Between July 2020 and August 2021, gravels at 29 sites in the Sauk, Suiattle and White Chuck rivers were collected and sorted into simple lithologic categories. The data

Accelerometer scour monitor data on the Sauk River, Washington, Water Year 2018

Accelerometer scour monitors were deployed on the Sauk River, Washington during Water Year 2018 as part of a study on the timing of streambed scour in salmon-spawning habitat. This data release contains data of the three-dimensional orientation recorded at 15-minute intervals for the accelerometer monitors. Each accelerometer scour monitor was comprised of one to two individual accelerometers that

Suspended Sediment and Water Temperature Data in the Suiattle River and the Downey Creek Tributary, Washington for select time periods over 2013 - 2017

This data release provides suspended-sediment (concentration and load) and water temperature data for two locations along the Suiattle River (USGS 1217900 and 12188380) and a tributary, Downey Creek (USGS 1217985) in Washington State for partial periods over 2013-2017. Suspended-sediment and water temperature data were collected over two summer seasons from May through September 2016 and 2017 at U

Supporting Datasets for Proglacial Topographic Change Analyses on Mount Rainier, 1960 to 2017

This data release is a repository for data presented in Anderson and Shean (2021), a publication looking at topographic change in proglacial and glacier-marginal areas on Mount Rainier between 1960 and 2017. Datasets include all newly derived digital elevation models, shapefiles defining various areas of analysis, and tabular summaries of data presented in figures. See individual child items and o

Sediment chemistry and characteristics of samples collected in 2019 from the Similkameen River above Enloe Dam, Okanogan County, Washington

This data release provides information on the chemistry and character of bed sediments accumulated in the 1.6-mile long impoundment behind Enloe Dam on the Similkameen River in Okanogan County, WA. Sediment samples were collected during four weeks in October - December 2019. The sampling locations were distributed among 10 transects that ranged from 0.1-0.2 miles apart along the length of the rese

Counts, Fish Weights, and Spectral Data from a Juvenile Chinook Salmon Polyester Microplastic Fiber Exposure Study

This release includes all data collected in support of a juvenile Chinook salmon exposure study designed to understand the retention of microplastic clothing fibers (hereon referred to as "microfibers") after feeding. To understand the potential impacts of microfiber ingestion to fish, we ran a feeding experiment with juvenile Chinook salmon to determine if ingested fibers are retained and/or dige

Water temperature and riparian vegetation survey data for the lower Quinault River, WA for select periods in 2018 and 2019

This data release includes hourly water temperature data at 12 locations in the main stem of the Quinault River and its major tributaries, and data from a riparian vegetation survey conducted in the lower Quinault River, Washington. Water temperature data was collected during the summer of 2018 and 2019 at most locations. Variable collection periods by site are described within the dataset. Ripari

Non-linear baseflow separation model with parameters and results

This data release provides source code and an R workspace with functions comprising a non-linear baseflow separation model, calibrated values of parameters and estimates of the baseflow component of daily streamflow at selected streamflow gages. Parameter values were determined by calibration of the model. Estimates of the baseflow component include daily values and the total baseflow as a fractio

Water quality and seepage estimates collected at Lake Spokane, WA, 2016-2019

Shallow nearshore groundwater chemistry and estimates of groundwater seepage were collected across 21 locations along Lake Spokane, WA, beginning in October 2016 and ending in October 2019. Groundwater chemistry was collected using temporary mini-piezometers and seepage rates from Lee-type seepage meters. Sample locations are divided into two distinct types: Core sites, where seepage data and grou

Bathymetry of the Similkameen River Above Enloe Dam Near Oroville, Washington

This data release provides the results of the bathymetric survey of the Similkameen River directly above Enloe Dam which took place over three days in late September 2020. The bathymetric survey was completed to enable an instrument-based estimate of the volume of legacy sediment impounded behind Enloe Dam. A shoreline water level survey collected points at the river?s edge using Trimble R8 GNSS
