Mid-spencer Island Restoration
The dikes of Mid-spencer island breached (in the 1960's), resulting in restoration of tidal flow but poor connectivity. Snohomish County is developing designs to remove additional dikes to support more complex channel formation, and improve fish access. Work will be completed as part of the Smith Island Restoration
- Unclear how construction will be phased in relation to the two-year Smith Island work.
- ESRP Contract in PRISM
- Conceptual Design
- NWFSC has completed some initial monitoring of fish composition and density within the island, however the high tidal channel connectivity has made strong sampling methods like fyke netting difficult.
