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.

Topographic survey sheets from Chittenden's 1907 flood report, lower White, Duwamish and Puyallup Rivers

Hiram Chittenden was an army engineer tasked with studying flood control issues in the White River watershed in 1907, following the major 1906 avulsion of the White River. As part of that work, he conducted a series of detailed topographic surveys of the lower White, Puyallup and Duwamish Rivers in 1907, including regular river cross sections and notations of water surface heights, both

Supporting Data for Sediment Studies in the White River Watershed

The White River is a dynamic gravel-bedded system in western Washington, with headwaters on Mount Rainier. Chronic aggradation in the lower river has reduced flood conveyance to a point where modest discharges are increasingly causing substantial flood damage. In order to better understand the dynamics governing this aggradation, and how aggradation rates may be influenced by forecasted chang...

Groundwater Watch

Groundwater Watch displays maps, graphs, and tables describing real-time, recent, and historical groundwater data from wells and springs across the United States. Groundwater Watch groups related wells and data from active well networks and provides basic statistics about the water-level data collected by the USGS and from data supplied to us from partners through cooperative agreements.

Accelerometer scour monitor data on the South Fork Tolt River, Washington, Water Year 2016 - 2017

Accelerometer scour monitors were deployed on the South Fork Tolt River, Washington from Water Year 2016 to 2017 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 two individual...

2018 Longitudinal Water Temperature Profiles of the Yakima River, Washington

Longitudinal profiles of near-streambed water temperature were measured at ambient river velocity using the method of Vacarro and Maloy (2006) within nine reaches of the Yakima River between Sunnyside Diversion Dam near Parker, WA and the confluence of the Yakima River with the Columbia River near Richland, WA. In eight reaches, near-streambed water temperature was measured along three
