Description    


The Beyeler Ranch Upper Lemhi Habitat Enhancement Project will enhance habitat on 2.4 river miles of the Lemhi River. Sections of this reach are entrenched and straightened with minimal riparian habitat. High velocity flow with little instream habitat prematurely flushes juvenile salmonids downriver. The proposed project will improve habitat forms and processes for juvenile spring Chinook salmon and summer steelhead in an area identified as high-priority by the Upper Salmon Integrated Rehabilitation Assessment (OSC 2017). Juvenile salmonid habitat enhancement will be accomplished through increasing channel length by reactivating meanders that have been cut off due to willow removal; narrowing the channel through treatments such as island formation, bank building, and creating bank deposition areas; providing low velocity habitats by adding small woody debris and wood structures, barbs/deflectors and willow weaves; and planting and protecting (fencing) willows in key areas. Streambank stabilization using logs, log barbs, revetments, and vegetation will occur on 1.43 miles of streambank. Project actions will provide overwintering and summer habitat for juvenile fish and address limiting factors for salmonid production in the Lemhi River such as reduced stream complexity and channel structure, excessive fine sediment, and degraded riparian conditions (NOAA Fisheries 2019). The project will be implemented in three phases; this request is for Phases I and II, occurring from 2020-2022 on 1.6 miles of the Lemhi River.

Project Benefit    


Additional channel length with slower water, access to floodplain, woody instream habitat, and overhanging riparian habitat are some of the key benefits to juvenile salmonids that will be realized by the project. Increased channel length will provide additional habitat area, decrease channel slope, and decrease instream velocity. Channel narrowing will increase channel depth for increased vertical (bank) habitat, decreased solar input, and increased fish cover. Woody habitat will create complex assemblages to provide feeding areas, cover, and velocity refuge during the summer and concealment habitat during the winter for juvenile salmonids. Woody instream habitat will also provide substrate scour and sorting which will benefit adults during migration, staging, and spawning.



Willow planting and protection will be conducted in areas where channel migration is occurring at an unnaturally high rate due to historic willow removal actions. In these areas, excessive channel migration, facilitated by willow removal, has been the mechanism for formation of overly wide channels that cut off meanders, thus becoming wider, shallower, and steeper, with higher water velocities and reduced habitat complexity. Willow planting and protection in these areas will ultimately reverse these trends.
