Description    


The objective of the project is to prepare a 100% design, analysis, and basis of design report for the 190-acre Bobcat Flat Phase III site.



Design objectives include:



1. Lower 64 acres of river adjacent surfaces to restore floodplain connectivity.



2. Replenish mainstem in-channel coarse sediment supply to restore geomorphic function.



3. Construct new off-channel habitats.



4. Restore mainstem salmonid habitat quantity and quality.



5. Restore natural riparian function.



6. Add 64,000 cubic yards of spawning gravel replenishment

Project Benefit    


The restoration design for the project will restore mainstem pool-riffle sequences and eliminate the disconnected off-channel habitat features. Restoration will reduce warm predatory habitat and increase coldwater habitat that is desirable for target salmonid and other special-status species.The Project design will also include wetland (0.18 acre), pond (0.33 acre), and side channel features (1.1 miles). These features will increase habitat diversity over a range of flows, connect with new, lowered floodplain surfaces, support riparian habitats, and increase groundwater recharge in and adjacent to the project area.The project will restore up to 64 acres of native, riparian vegetation.
