4. Palouse Creek Culvert

5. Fish Passage Improvements Culverts are usually barriers when: Culverts are usually barriers when: Perched Perched Higher sloped than the adjacent stream Higher sloped than the adjacent stream Significantly undersized Significantly undersized Blocked by a tidegate Blocked by a tidegate

6. Willanch East County Bridge Fish Passage Project Culvert was a fish barrier because: 6” outlet drop 9% gradient (no stream substrate for roughness) Undersized (4-foot diameter on a 14-foot wide channel)

7. Fall Creek Culvert Fish Barrier because: Perched 1-foot Undersized for stream Double culverts plug more easily

8. Tide Gates Tide gates cause fish passage problems: During high tide When culvert is undersized If gates cause high velocities when open If structure is failing

9. Large Stream Tide Gates Side-hinge designs Side-hinge designs Open with little head difference Open with little head difference Reduce velocities Reduce velocities Reduce period gates are open Reduce period gates are open

10. Roads and Sediment Road erosion is caused by: Road erosion is caused by: Undersized culverts that wash out Undersized culverts that wash out Undersized culverts that divert Undersized culverts that divert Excessively long ditches Excessively long ditches Side-cast roads that slide out Side-cast roads that slide out

11. Removing Abandoned Roads Improve fish passage Reduce risk of stream crossing failures Reduce chronic sediment inputs

12. Forest Road Decommissioning Reduce landslide risk Improve natural drainage (flood mitigation) Reduce unwanted trespassing

13. Rogers Tributary Channel Construction

16. Fall Creek Wood Placement Large wood benefits: Gravel deposition Gravel deposition Pool scour Pool scour Cover from predators Cover from predators

17. Willanch Creek Wood creates slack-water areas during high winter flows for juvenile salmon and other fish

18. Riparian Restoration Stream-side Planting Reasons for planting stream banks: Increase bank stability Replace unwanted weeds Improve habitat for birds and wildlife Shade streams

19. Packard Creek Riparian Planting Fencing excluded cattle from stream Fencing excluded cattle from stream Roots stabilized banks Roots stabilized banks Canopy helped shade stream Canopy helped shade stream

20. Packard Creek Riparian Planting Native vegetation planted in spring 2003 improved stream temperatures during the second year of growth.

21. Conservation Reserve Enhancement Program Pays rental money for stream buffer acres Pays rental money for stream buffer acres Cost-share money for planting, fencing, off-channel watering, and stream crossings Cost-share money for planting, fencing, off-channel watering, and stream crossings

22. Wetlands Appropriately managed wetlands can provide: Rearing habitat for juvenile salmon Floodwater storage and retention Bird and wildlife habitat Natural water purification systems
