Description
Scope/Content: Abstract: The U.S. Army Corps of Engineers, San Francisco District (Corps), and the City of St. Helena, California, the project's non-Federal sponsor, propose to remove or modify Upper York Creek Dam and appurtenances, remove accumulated sediment, and restore the local ecosystem structure. Removing or modifying the dam would improve fish passage for the federally listed steelhead (Oncorhynchus mykiss), would reduce the potential for future downstream sediment releases and fish kills, and would allow for the restoration of approximately 3 total acres of degraded riparian and riverine habitat surrounding Upper York Creek Dam. This report presents the findings of the alternatives analysis and the selection of a recommended plan for the Upper York Creek Ecosystem Restoration Project.
Scope/Content: Dam type: earthen
Scope/Content: Height: 50 feet. Length: 140 feet.
Scope/Content: Date constructed: 1902.
