Data

Publicly Accessible

We are committed to providing data and information to the public.

Reliable

Our data are collected following rigorous quality control standards.

Unbiased

The USGS has a non-regulatory mission.

Long-standing

Our water monitoring network is over 100 years old in many parts of Washington State.

View our history

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 Water Information System (NWIS) database and the National Water Dashboard.

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

Topographic and bathymetric surveys of the Nooksack River completed 2015

Bathymetric and topographic data on the mainstem Nooksack River, Whatcom County, Washington were collected in the fall of 2015 as part of a study on sediment transport and channel change. Bathymetric data was collected from the river's mouth to river mile (RM) 28, near Nugent's Corner. Topographic data is available from RM 17, near the town of Lynden, to RM 37, near the confluence of the Middle Fo

Sediment chemistry and sediment toxicity in wadable streams across the Midwestern United States, 2013

These data present chemistry and toxicity results from freshwater stream sediments collected from 99 wadable stream sites across eleven states in the Midwestern U.S. as one component of a larger USGS study in the summer of 2013. This data presents a selected suite of chemistry collected at these sites (PAHs, Organochlorines, PCBs, Trace Elements, and current use pesticides) used in calculating a P

Trace elements concentrations in pore water and surface water near the sediment-water interface in the Upper Columbia River, Washington (2015)

Smelter slag containing copper and other trace elements is widespread in riverbed sediment of the upper Columbia River (UCR) of the United States. To evaluate potential risk to aquatic life concentrations of copper and other trace elements were measured in shallow pore-water and in river water samples collected near the sediment-water interface. Samples were collected using an in-situ pore-water p
