GOES satellite telemetry data transmissions from a subset of our network are experiencing an interruption in service. This outage is impacting multiple channels on the GOES East and West satellites nationwide. Station websites will resume reporting when service is restored nationally.

This station records lake level only. Adjudicated Lake level = 86.33 ft on the graph (NAVD 88 Datum)
Warning: station may be affected by ice during periods of extreme cold weather.
During extreme cold weather, river stage may be affected by ice. As a result of the changing channel characteristics, incorrect discharge data will be computed from the stage data. Please review associated water and air temperature data where available.

Station description

In June 2006, the Washington State Department of Ecology, in cooperation with the Stevens County Public Utility District installed a real-time lake level gage in Loon Lake. This gage is used by Ecology, Stevens County Public Utility District, and Loon Lake Sewer District No. 4 to manage the lake level and estimate needed discharge from the lake during spring and summer months. The maximum lake level of 2381.25ft (NGVD 1929) was fixed by order of the Stevens County Superior Court in February 24th 1950. This is equal to 2386.33 ft (NGVD 88). The Ecology gage references the lake surface elevation based on the Granite Point bench mark of 2388.73 ft. (NGVD 88). This gage provides water resource managers and the public an avenue to observe real time lake level conditions. Having this information will help prevent property damage, help estimate water availability, and help determine lake outlet discharges.
