Description    


The Lower Tryon Creek Passage and Off-Channel Habitat Design Project successfully developed 100% designs to restore salmonid habitat by improving fish passage and off-channel habitat at and adjacent to two road stream crossings known to limit fish passage on Tryon Creek. Once implemented, the project will ensure access to the lower 4.13 miles of habitat in the subbasin. The project will improve the floodplain connectivity and reduce potential fish stranding, enhance riparian habitat and provide seasonal livestock exclusion.

Project Benefit    


The specific objective of the Project is to restore salmonid habitat by improving fish passage and off-channel habitat at and adjacent to two road-stream

crossings known to limit fish passage on lower Tryon Creek. The Project will develop restoration designs that will lead to implementation projects to address

fish passage and off channel habitat.

          Description and scope of the plan implemented
          The project will address a recovery task from the Southern Oregon and Northern California Coast Coho Salmon recovery plan SONCC-SmiR.5.1.14.2: Remove barriers, based on evaluation. Barriers to fish passage are listed as a high threat to the juvenile and smolt life stages for coho salmon in the Smith River (NMFS 2014). Removing barriers is identified as one of the highest priority recovery actions for the Smith River coho salmon population (CDFW 2004, NMFS 2014). The project successfully developed 100% designs restore salmonid habitat by improving fish passage and off-channel habitat at and adjacent to two road stream crossings known to limit fish passage on Tryon Creek. The project designs identified the best means to create refugia habitat (SONCC.SmiR.2.2.3.1) adjacent to crossing #1. Smith River Alliance and Stillwater Sciences completed a series of studies to inform the development of 100% designs to improve fish passage and off-channel habitat. The design approach utilized existing data sets, hydrologic and hydraulic assessments, topographic, geomorphic, and riparian assessments to collectively inform restoration planning and conceptual design development. Existing and new data, subsequent analyses, and input from a Technical Advisory Committee were used to inform all design phases, including 30%, 65%, 90%, and final 100% designs.
