Mid-Columbia Regional Fisheries Enhancement Group reintroduced approximately one mile of lower Reecer Creek in Ellensburg, WA to its floodplain; increased stream channel length, complexity and habitat area; established native riparian and upland vegetation; and installed log structures to support natural channel forming processes, enhance habitat and improve water quality. Project objectives were to improve the floodplain ecosystem function of Reecer Creek within 58 acres of historic floodplain near its confluence with the Yakima River by: 1) relocating 3,700 ft of diked/channelized creek onto its re-contoured floodplain, recreating complex channel conditions mimicking those created by natural stream processes; 2) stabilizing the channel and floodplain with appropriate riparian and floodplain vegetation; 3) creating initial conditions of dynamic equilibrium (i.e., balanced sediment transport); and 4) increasing the quantity and quality of aquatic habitat by increasing channel length (from 3700 ft of straightened channel to 4800 ft of meandering channel), increasing channel complexity and improving width, depth, and velocity characteristics. The project created spawning, rearing, holding, and foraging habitat for resident and salmonid fish, including Chinook, Coho, and steelhead. The design was intended to dissipate flood flow energy, increase infiltration and water holding capacity, support ground-surface water interactions; and promote water quality (temperature, turbidity) and natural sediment management (deposition, suspension).
