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)
