Document Description
The purpose of the project is to initiate restoration of natural processes that self-sustain healthy valley bottoms and riparian habitats. Four (4) rock check structures, three (3) post-assisted beaver dam analogues (BDAs), three (3) rock rundowns, and six (6) one-rock dams crossing Elysian Creek will be installed. Rock check dams and beaver dam analogs in Elysian Creek are expected to provide protection against excessive runoff by trapping sediment during times of excessive water flow rate. Long-term effects will include reduction in bank erosion, head cutting, and channel incision. Beaver dam analogues are low-tech woody structures designed to facilitate process-based restoration of stream and riparian areas. These structures are built with natural vegetation and sod woven around untreated wood posts. Structure lifespan is short, but promotes the natural accumulation of sediment and natural debris to replace itself with more long-lived materials. The consequent slowing of water flow through the valley is expected to recharge the groundwater and supply the valley floor with enough water to improve wildlife habitat.
