The CCCD, on behalf of the Entiat WRIA Planning Unit (EWPU), will implement Phase I of a full ~1.2 RM reach restoration in the lower mainstem Entiat River. The "Bridge-to-Bridge" (B-to-B) reach (~RM 3.2 to RM 4.4) is the highest priority restoration area in WRIA 46. Past activities that have altered the lower Entiat River include logging, dams, stream clearing; channelization, filling & flood control protection works. Riparian vegetation has been removed by fire & development. The B-to-B effort addresses lack of off-channel rearing habitat, temperature extremes & habitat simplicity. It will restore geomorphology, floodplain function, habitat complexity/diversity, off-channel habitat, and shading, benefiting adult & juvenile Chinook, steelhead & coho. At the end of Phase 3, the reach will be restored to its geomorphic potential (e.g. now 0.3 pools/mi, restored to 9 pools/mi). The EWPU supports this 3-phase project, developed via 10 years of planning. Actions proposed are based on geomorphic, biologic, hydrologic & thermal analyses. Funding for Phase 1 will be used to: (a) restore ~1000 contiguous ft. of riparian vegetation to improve stream temperatures, bank condition, cover, nutrient inputs; (b) provide juvenile off-channel rearing habitat via rock/LWD placement in ~700 ft. irrigation ditch; (c) install 2 instream structures to direct flow to the off-channel habitat and restore resting pools in the lowest portion of the reach. A ditch outfall structure will also be added.
