Indian Rock Dam is a popular recreational area located in York County, Pennsylvania. The dam was built in the early 1900s to control flooding along the Codorus Creek. The Indian Rock Dam provides water to the nearby city of York and is an important source of hydroelectric power. The dam's hydrology is influenced by specific surface flow and snowpack providers. The Codorus Creek is the primary provider of surface flow, while snowpack accumulation in the surrounding mountains contributes to the dam's water levels during the spring and summer months. The Indian Rock Dam is also used for agricultural purposes, providing irrigation to nearby farms. The area is a popular destination for outdoor enthusiasts, offering hiking trails, picnic areas, and fishing opportunities.
