About the Indian Rock Dam Master Plan Revision

Indian Rock Dam is located about three miles upstream from York, Pennsylvania. The dam is a part of the Indian Rock Dam/Codorus Creek Project, which includes channel improvements on Codorus Creek. The Indian Rock Dam/Codorus Creek project has prevented an estimated $54.6 million in flood damages for the local community.

The Indian Rock Dam project was authorized by the Flood Control Act of June 22, 1936, as amended by the Flood Control Act of June 28, 1938. The normally dry reservoir has a storage capacity of 28,000 acre-feet (9.1 billion gallons) at spillway crest and controls a drainage area of 94 square miles, equivalent to 41 percent of the watershed upstream from York. In conjunction with the Codorus Creek project, these projects reduce risk to the York community against flood discharges about 33 percent greater than the record flood of August 1933.

Master Plans are project-centered documents designed to provide a framework for consistent, responsible decision-making for the next 15 to 25 years for dam sites throughout the Corps.  The Indian Rock Dam Master Plan Revision is a part of a larger, Corps-wide effort to bring master plans up to date across the country. The primary goals of the Indian Rock Master Plan revision are to improve infrastructure and utilities, enhance existing recreation sites and amenities and invest in key operational and support facilities.

Master Plans have no set timeframe for revisions, but they are developed to have an effective lifespan of 15 to 25 years. The current Master Plan for Indian Rock Dam dates back to 1959.

The Master Plan revision will not change the technical operations of the dam related to its primary mission of flood risk management.
