STREAM PROJECTS

 

Project: Wood's Creek Restoration
Location: Teton Valley, ID
Date: 2004
Goal:
Restore degraded habitat for native Yellowstone cutthroat trout on two reaches of a local spring creek.

Description:
Wood's Creek is a small spring creek tributary to the Teton River and is located just west of Driggs, Idaho. Past agricultural practices have resulted in degraded banks, increased sedimentation, a lack of spawning riffles, loss of riparian vegetation and therefore limited in-stream cover and available trout habitat. Previously installed culverts in several locations were causing further bank instability and erosion as a result of having been improperly sized and placed. Electrofishing conducted prior to the restoration work identified a limited number of relatively small trout, and no trout over 10' in length. The project addressed these issues by excavating pools to provide holding water for adult fish, creating spawning riffles and re-sloping the severely eroded banks. The pools were complimented by a mix of point bar constrictions and logs to provide the scour to maintain their depths. Transplanted willows were placed along the bank to provide additional cover and stability. The failing culverts were removed and two bridges which span the entire creek were installed. Several large trout (>12') were observed utilizing pools within the first week after construction. Intermountain Aquatics completed the revegetation of the re-sloped banks in the summer and continue to monitor the success of the project.
