  1. Resident Fish Mitigation • RESIDENT FISH LOSS ASSESSMENT • Fish and Wildlife Program provides for • resident fish mitigation (through the • acquisition of property) where construction and • inundation losses have been assessed and • quantified • Primary purpose is to preserve, enhance, restore, and/or create habitat equal to the quantity and quality of habitat lost.

  2. Resident Fish Mitigation • LACK OF LOSS ASSESSMENTS ACROSS THE BASIN • Loss assessments required to purchase property • Examples of Existing Habitat Loss Assessments • MFWP – Hungry Horse Reservoir • IDFG – Upper Snake River reservoirs

  3. Resident Fish Mitigation • LACK OF STANDARD METHOD • Program does not prescribe specific methodology for assessing quantity of habitat lost (i.e., inundated) • RFAC - need a standardized method for assessment due to ledger accounting

  4. Resident Fish Mitigation • PROPOSED METHOD • Length or area (at discretion of entity) calculated using GIS (1:12,000 scale) and stream order • Waterway length or area measured to full pool elevation • If bridges or culverts (associated with construction) function as barriers length of stream above should be included
