DESCRIPTION
This project will accomplish three elements of the Middle
Nemah River Priority Watershed Restoration program. 1. Complete
restoration in the Phase 1 area in the lower river, placing engineered log jams
to improve habitat complexity and address an avulsion risk where the entire
river would enter a series of gravel extraction ponds which would trigger a
damaging head-cut and disconnect ½ mile of main channel. 2. Complete
Phase 2 restoration actions in the upper watershed placing Accumulations of
large wood by helicopter to improve habitat complexity. 3. Complete
designs for the Phase 3 reaches in the middle watershed.
This project will complete restoration in the Phase 1 area of the Middle Nemah River which is the Priority Watershed for the Willapa Bay Lead Entity. The restoration will focus in a high priority area in the lower river, placing engineered log jams to improve habitat complexity and addressing an avulsion risk where the entire river would otherwise enter a series of gravel extraction ponds which would trigger a damaging head-cut and disconnect 1/3 mile of main channel. And the project will improve floodplain connection in the pond area where the avulsion risk is low and elsewhere within the reach by removing segments of an abandoned road.
