Hover over one of the small icons on the map below to find a continuous monitoring station, and click to go see the latest values. Click the link in the pop-up box to go to the station page. Choose a regional map to take a closer look.
Using River and Stream Flow Data has further information on how to use this map.
Also, the Washington State Streamflow Summary Map displays current water levels compared to reference conditions.
Descriptions of station types:
1. A telemetry station transmits data every three hours to the Department of Ecology Headquarters in Olympia, Washington. The data is logged every fifteen minutes and transmitted in three hour blocks to Ecology where it is automatically imported into the streamflow database and published to Ecology's website. The data is transmitted via either a GOES satellite transmitter or a standard dial-up modem.
2. A manual-stage-height station does not contain a continuous record. A manual-stage-height station consists of a series of periodic gage readings related to a series of instream flow measurements. Gage readings are from either a standard staff gage, wire weight gage (WWG) or from a reference point (RP). An RP is a point located somewhere over the wetted width of the station cross-section where a measurement can be made to the water surface. The correlation between these gage readings and the instream flow measurements is used to develop a rating table for the site.
