National Dam Inspection Program. Colver Dam (NDI I.D. PA-0437, DER I.D. 11-20), Ohio River Basin, North Branch Blacklick Creek, Cambria County, Pennsylvania. Phase I Inspection Report
The dam is classified as a small dam in the significant hazard category. In view of the size of the dam which is closer to the lower limit of the small size classification, the 100-year flood was selected as the spillway design flood. The 100-year flood peak was determined according to the recommended procedure and was found to be in excess of the spillway capacity. Therefore, the capacity of the spillway is classified as inadequate. The following recommendations should be implemented immediately on continuing basis: (1) The owner should determine the nature and extent of modifications needed and implement these measures to provide adequate spillway capacity; (2) Around-the-clock surveillance should be provided during unusally heavy rainfall and/or runoff. In addition, a formal warning system should be developed to alert downstream residents in the event of an emergency; and (3) The owner should develop and follow a formal operating and maintenance plan and should inspect the dam regularly.
