Approach

Decrease fragmentation of stream network so fish can access similar habitats.

Tactics

  • Identify stream crossings that impede fish movements and prioritize culvert replacement.
  • Use stream simulation design (e.g., bottomless arches, bridges), adjusting designs to provide low-flow thalweg.
  • Rebuild stream bottoms by increasing floodplain connectivity, riparian vegetation, and water tables; decrease road connectivity.
  • Restore beaver habitat and beaver colonies.
  • Maintain minimum streamflows (buy and lease water rights, install modern flow structures, monitor water use).
