Middle Fork Porter Creek Reach Phase 1 Restoration Project
TRI_0085
The Lummi Nation will design and construct 11 engineered log jams (ELJs) in the mainstem Middle North Fork Nooksack River. Endangered early spring Chinook salmon and bull trout will benefit from 11 new primary pools; more pools may develop indirectly as increased roughness causes dynamic equilibrium. Scour pools provide thermal refugia (holding pools) from elevated Middle Fork water temperatures during summer spawning months in addition to pools for juvenile overwintering (rearing pools). In addition, juveniles will benefit from 1.23 miles of off channel rearing habitat by increasing connectivity with the floodplain and side channels. All features are focused on enhancement of endangered Spring Chinook (Oncorhynchus tshawytscha) habitat by maximizing natural habitat-forming processes inherent in this reach of river.
