Eagle Creek Reservoir Dam in Marion, Indiana, stands as a critical structure designed for flood risk reduction and water supply purposes. Completed in 1967, this earth dam towers at a height of 85 feet, with a hydraulic height matching that figure. The dam's structural height reaches 92 feet, with a length of 5,100 feet and a storage capacity of 110,000 acre-feet.

With a normal storage capacity of 24,000 acre-feet and a surface area spanning 1,350 acres, Eagle Creek Reservoir Dam plays a vital role in managing water resources in the region. The dam's spillway, controlled and 240 feet wide, serves as a key component in regulating water discharge during high flow events. Despite its high hazard potential and poor condition assessment as of December 2006, the dam undergoes regular inspections, with the last one conducted in June 2018.

Located along the Eagle Creek river, this dam's strategic placement and design ensure the protection of surrounding communities from flooding while also providing a reliable source of water supply. As climate change intensifies and water resources become increasingly scarce, Eagle Creek Reservoir Dam serves as a crucial infrastructure safeguarding against the impacts of a changing climate on water availability and flood risk in the region.
