Document Description
The project consists of implementing several modifications to the existing Cottage Creek Dam to prevent potential future public safety issues associated with aging infrastructure. The modifications consist of removing the existing corrugated metal pipe spillway and downstream culvert, excavating a portion of the dam down to a lower elevation and installing a large concrete box culvert sized to pass all Cottage Creek flows downstream past the Cottage Creek Dam and into New Bullards Bar Reservoir. This will result in the drainage of Cottage Creek Reservoir and conversion of the existing open water habitat into wetland and streambed. The portion of the dam embankment not impacted by the new box culvert will remain in place, as will the existing water treatment facilities.
