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.

Soil Water Balance Model of Upper Chehalis River Basin, Southwestern Washington

This archive documents a Soil Water Balance (SWB) model of the 895-square mile upper Chehalis River Basin upstream of Grand Mound, Washington. The SWB model used to estimate a water budget (including precipitation, interception, groundwater recharge, surface runoff, and groundwater pumping) for the upper Chehalis River Basin during October 2001–September 2015.

Groundwater data for Washington

Data from wells, springs, test holes, tunnels, drains, and excavations in Washington; well location data includes information such as latitude and longitude, well depth, and aquifer. Groundwater level data are collected and stored as either discrete field-water-level measurements or as continuous time-series data from automated recorders.

Water-quality data for Washington

Chemical, physical, and biological properties of water, sediment, and tissue samples from Washington. Water-quality data are collected as either discrete field measurements or as continuous time-series data from automated recorders that continuously record physical and chemical characteristics including pH, specific conductance, temperature, and dissolved oxygen.

Water-use data for Washington

Water-use data is collected by area type (state, county, watershed, or aquifer) and source (such as rivers or groundwater), and category (such as public supply or irrigation). Water-use data has been reported every five years since 1985. The USGS works in cooperation with local, State, and Federal agencies as well as academic and private organizations to collect and report withdrawals.
