Location: The project site is on private property in the Lemhi Valley, approximately 40 miles south of Salmon, Idaho and 6 miles north of Leadore, Idaho.

General Overview, Purpose of Proposal:
This project will improve bank, channel and riparian conditions to address shade and habitat in areas where existing channel geometry and riparian vegetation is impaired. It will maximize short-term and long-term riparian and shade conditions to address established shade targets, reduce the channel width to a more appropriate geometry, and improve thermal refuge by increasing the frequency and magnitude of self-maintaining pools. The work shall include, but not be limited to, the following activities as shown on the plans: preparation of construction access routes; installation and removal of temporary cofferdams and channel diversion structures; dewatering; creation of constrictions to allow the channel to scour pools and to narrow and deepen the channel; earthwork within the existing active channel zone to force flow against adjacent mature riparian vegetation; relocation of three stream segments to increase sinuosity; installation of multiple woody debris structures to prevent erosion; installation of a variety of edge treatments using FESL where the channel is narrowed; transplanting wetland sod; re-vegetation and seeding; reclaiming and restoring all construction access areas; fencing; irrigation. All work shall be completed in accordance with the contract provisions, the technical specifications, and Drawings.
Project Timeline:Bid Awarded on or before July 28, 2017. Project should begin work by September 1, 2017 and completed by January 31st, 2018.
