Lemhi River Salmon Habitat Restoration
· Relocated stream segments to utilize existing native vegetation to create immediate increases in shade conditions
· Created channel constrictions to allow the channel to scour pools and deepen the channel
· Utilized a diversity of treatment types to enable comparison and evaluation of best practices for future projects
Services Provided: Topo & Bathymetric Survey; Wetland & Native Vegetation Survey; Edge Treatment & Native Plant Revegetation Plans; 404 Permitting; Construction Management; Post-project Monitoring
Flow Range: 40 – 350 cfs
Design Approach: Intermountain Aquatics provided ecological design support to the RIO Applied Sciences & Engineering team for this project. Intermountain Aquatics developed innovative edge treatment designs to ensure that robust boundary conditions were established throughout the project area and assisted with channel pattern designs to utilize existing mature, native vegetation.
