DESCRIPTION
The North Fork/Middle Fork early Chinook population is considered essential for ESU recovery, but population productivity is substantially less than that needed to sustain and recover the population. A recent assessment and restoration planning report identified limiting habitat factors and causes of habitat degradation and recommended specific restoration strategies by reach. The Farmhouse reach of the North Fork Nooksack River (RM 46.4-49.4) is one of two project reaches among 14 reaches that scored highest in terms of restoration potential in the North Fork Nooksack River. This project advanced the design of restoration throughout the Farmhouse Reach that will restore historic channel planform, habitat diversity, and habitat functions, including stable spawning and rearing habitats for NF/MF Nooksack early chinook.
Specific tasks included: (1) feasibility study, including refinement of limiting factors and reach-specific objectives, identification and evaluation of various alternatives, landowner outreach, and selection and staging of the preferred alternative; (2) preliminary (30%) design and phasing for the reach-scale, six-phase preferred alternative, including hydraulic modeling, geomorphic assessment, and cost estimates; and (3) final design, permits, and flood risk assessment for Phase 1 of construction. The final Phase 1 design is being constructed in the funded NF Farmhouse Restoration Phase 1 project (RCO-SRFB #13-1276).
