Seiad Creek at Panther Gulch Coho Habitat Enhancement Project

This project will improve spawning and rearing conditions for Coho Salmon by: 1) constructing a minimum of 26 wood structures to encourage braiding, channel aggradation, and floodplain connectivity, 2) constructing 3 side channels for 950 ft of new channel, 3) creating 2 off-channel ponds for 6,900 square feet of new low velocity habitat, and 4) widening the channel at 4 areas to reduce stream velocities and to increase floodplain inundation. There will be ≈ 1.65 acres of increased inundation during the 2-year flow event. The project is shown and described in the 100% Design Plan and associated Basis of Design Report, uploaded to the Supplementary Documents section of this proposal.

This project is expected to benefit salmonids by increasing the amount of spawning gravel, and will provide juvenile Coho Salmon with year-round rearing habitat.
