The Piney Run Reservoir is the focal point for Piney Run Park in Carroll County, Maryland. Used by citizens throughout the summer for boating and fishing, the reservoir is also an important resource to the county for flood control and future water supply.  Many don’t realize that the water is held back by a 74-foot-tall earthen dam, the largest dam owned by Carroll County. Due to the dam's size and the risk, if something were to happen to it, the dam is classified by the Maryland Department of the Environment (MDE) as a “High Hazard Dam.” This means that the County and MDE take extra precautions to ensure that it is inspected annually and well-maintained.
