Dehart, also known as Clarks Valley Reservoir, is a local government-owned water supply dam located in Rush Township, Dauphin County, Pennsylvania. Managed by the Pennsylvania Department of Environmental Protection, this earth-type dam stands at a height of 105 feet and was completed in 1940. With a storage capacity of 30,800 acre-feet and a surface area of 592 acres, Dehart plays a crucial role in providing water to the surrounding areas.

Despite its important function, Dehart has a high hazard potential and is currently assessed to be in poor condition. The dam has a history of modifications in 2009 and 2010, indicating ongoing efforts to maintain and improve its structural integrity. The last inspection was conducted in December 2020, with a frequency of one inspection per year. It is imperative for water resource and climate enthusiasts to monitor the condition of Dehart and support necessary risk management measures to ensure the safety and reliability of this vital water supply infrastructure.

As a key component of the water supply system in the region, Dehart serves as a critical resource for water management and flood control along Clarks Creek. With its significant storage capacity and strategic location, the dam not only supports the water needs of the community but also helps mitigate potential risks associated with flooding and water scarcity. As discussions around climate change and sustainable water resource management continue to evolve, the importance of maintaining and enhancing infrastructure like Dehart becomes increasingly evident for ensuring a resilient and secure water future.
