Teanaway Restoration Project

The Teanaway Basin currently experiences high stream temperatures detrimental to threatened salmonids (steelhead and bull trout) as well as to spring chinook and resident trout. There are eight waterbodies in this basin that have been identified on Washington State’s latest list of impaired waterbodies (the 1998 303(d) list) as being impaired for temperature (Ecology, 1998). Ecology verified these listings in 1998, when data showed that the middle and lower basin exceeded the 18ºC water quality standard in over 75% of the days monitored (Stohr, 2000). Additionally, the lower portion of the Teanaway mainstem has been identified as impaired for in-stream flows (Ecology, 1998). Stream temperature is increased by lack of riparian shade, excessive sediment load, and low stream flow. Land management activities, such as forest management, grazing, and agriculture, may affect temperature adversely where they damage vegetation adjacent to streams, cause excessive erosion of stream banks, add sediment to streams, reduce instream flow, or return warmed waters to the stream.
