Cottonwood Creek Dam, Idaho, Project
Cottonwood Creek project is to provide local flood protection to the eastern portion of the city of Boise, Idaho. The project planned would require 192 acres of land and would consist of a dam located approximately 200 feet below the confluence of Cottonwood and Freestone Creeks at the northeast city limits. The dam would be an earth and rockfill structure 117 feet high at crest elevation 2889. Streamflow is not dependable enough to create a good permanent lake behind the dam. The dam would become a major visual element extending across the foothill canyon. A small amount of wildlife would be displaced from habitat eliminated from lands occupied by the dam, spillway, and parts of the impoundment area. Sediment periodically trapped behind the dam would cover the existing canyon bottom and eliminate existing vegetative ground cover. No major adverse impact is foreseen.
