Bengal Dam, located in Sioux City, Iowa, is a privately owned earth dam constructed in 1973 by the USDA NRCS. The dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a height of 41 feet and a length of 288 feet, Bengal Dam has a storage capacity of 43 acre-feet and covers a surface area of 3.9 acres. It is regulated by the Iowa DNR and undergoes regular inspections to ensure its safety and functionality.

Despite being classified as a low hazard potential structure, Bengal Dam is considered to have moderate risk due to its location on TR-Broken Kettle Creek. The dam has an uncontrolled spillway and is designed to handle maximum discharges. It is situated in Plymouth County, Iowa, within the jurisdiction of the state regulatory agency. The dam's condition is currently not rated, and emergency action plans are not yet prepared, indicating a need for further risk management measures to be implemented to ensure the safety of the surrounding community and environment.

Bengal Dam stands as a vital water resource infrastructure in the region, providing essential functions for fire protection, agricultural activities, and wildlife habitat enhancement. As climate change continues to impact water resources, the management and maintenance of dams like Bengal Dam become increasingly important to ensure sustainable water supply and ecosystem health. With its rich history and multifaceted uses, Bengal Dam serves as a prime example of the intersection between water resource management, climate resilience, and community safety in the face of changing environmental conditions.
