Description    


Idaho Department of Fish and Game (IDFG) used contracted engineering consultants for habitat project development activities, prior to obtaining project-specific funding. This funding was used in the development and early design of restoration projects that directly address limiting factors of wild salmon and steelhead in tributary habitats in both the Clearwater and Salmon River basins. This funding played a crucial role in allowing habitat biologists to engage with engineers in initial site assessments, topographic surveys, feasibility analyses and evaluation of restoration treatment alternatives, as well as the development of design and construction cost estimates. This information is crucial for habitat biologists in the development and justification for project-specific funding requests. IDFG judiciously used these funds on high-priority projects addressing fish passage, in-stream habitat, and in-stream flow projects, with high likelihood of implementation.



Funds were used to pay for habitat project designs, contracting, and construction oversight in the Lemhi River, the Pahsimeroi River, the North Fork of the Salmon River, SQ Creek, and the Potlatch River. RivHab LLC, Quadrant Consulting Inc., and Tetra Tech Inc. were contracted for all projects funded in this grant.

Project Benefit    


IDFG has been involved in stream habitat restoration projects in tributaries to the Salmon and Clearwater River subbasins for some time. Those efforts have focused on improving spawning, rearing, and overwinter habitats in tributaries occupied or historically occupied by anadromous fish. Successful design and implementation of restoration projects requires applied science and engineering. Aside from fish-related information, stream habitat projects require careful surveys and intimate knowledge of hydrology, geomorphology, sediment transport, structural and civil engineering practices, and construction management. IDFG’s ability to include engineering consultation during initial project design has been influential in the success of the IDFG fish habitat program.

Addressing limiting factors of survival and production of Sp/Su Chinook Salmon and steelhead in Idaho tributary habitats requires restoration of physical habitat, natural processes, and hydrological functions (NMFS 2017). Restoration efforts will focus on improving spawning and rearing habitats, access to existing habitats (i.e., barrier removal), flow, riparian and floodplain habitats, channel complexity, and lateral habitat. The use of engineering techniques and materials to achieve and restore these processes requires careful and skilled river engineering to achieve goals such as spawning gravel recruitment or reconnection of a side channel (Louhi et al. 2016; Palmer et al. 2005; Pess et al. 2011).

          Description and scope of the plan implemented
          This funding was used to develop restoration projects that directly address factors limiting the production and survival of the ESA-listed Snake River Spring/Summer Chinook Salmon and steelhead populations in the Potlatch, Lemhi, NFSR, and Pahsimeroir river drainages. These basins has been heavily impacted by land practices such as agriculture, timber harvest, mining, and road construction. Restoration efforts will focus on improving spawning and rearing habitats, overwintering habitat, riparian and floodplain habitats, channel complexity and lateral habitat. This project supports the NMFS (2017) and NPCC (2014) recovery plans.
