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.

Accelerometer scour monitor data on the Cedar River, Washington, 2013 - 2014

Accelerometer scour monitors were deployed on the Cedar River, Washington from 2013 to 2014 as part of a study on the timing of streambed scour at 73 locations in salmon-spawning habitat. This data release contains data of the three-dimensional orientation recorded at 20- to 30-minute intervals for the 46 accelerometer monitors that were recovered in 2014.

Bathymetric DEM of the lower Nooksack River, August 2015

Bathymetric data for the mainstem of the Nooksack River during low flow conditions from 24 to 27 August 2015. Depth data were collected with boat-mounted single-beam echo sounder downstream of Ferndale, Washington and a boat-mounted acoustic doppler current profiler (ADCP) upstream of Ferndale.

Lower Cedar River Side Channels 2013

Side channels are small channels located parallel to the main channel of river that have a surface connection to the river at the upstream and/or downstream end. Connectivity may depend on river stage. Side channels are an important type of off-channel habitat for rearing of juvenile salmon and spawning by adults.
