Document Description
The Proposed Project consists 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 that would be sized to pass all Cottage Creek flows downstream past the Cottage Creek Dam and into New Bullards Bar Reservoir (approximately 1/4 mile downstream of the Cottage Creek Dam). These actions would result in the drainage of the existing Cottage Creek Reservoir. The existing Cottage Creek Reservoir would no longer capture water, but water would continue to move through the area and the former reservoir would function as a wetland.
