Description

This project was located on Thirtymile Creek, a tributary to the John Day River. Completed activities consist of channel structure placement, specifically placement of PALS and BDAs in order to create pool habitat and extend perennial flow.

Project Benefit

The project will facilitate floodplain expansion to enhance riparian community (improves, shading, provides cover, increases allochthonous nutrient input, etc.) and channel complexity.

The project will also facilitate incision recovery, improve stream health and restore ecological function to the stream. The increased physical complexity within the channel will be utilized by juvenile steelhead for habitat requirements (zones for feeding, energy conservation, predator refugia) and improve spawning conditions for adult steelhead.
The increased wetted extent of the channel during low flow conditions will increase the quantity of habitat available to juvenile steelhead during low summer flow as much of the stream flows intermittently.
