Bennington Lake Basin 1, located in Douglas County, Nebraska, is a vital water resource managed by the local government. This Earth type dam, completed in 2000, serves multiple purposes including flood risk reduction and other water management functions. With a height of 28 feet and a storage capacity of 775 acre-feet, this reservoir plays a crucial role in regulating the flow of the Big Papio Creek and protecting the surrounding area from potential water hazards.

Managed by the Nebraska Department of Natural Resources, Bennington Lake Basin 1 has a significant hazard potential but is currently in satisfactory condition, according to the last inspection conducted in May 2018. The dam has a hydraulic height of 31 feet and a structural height of 33 feet, with a drainage area of 2.6 square miles. The reservoir covers an area of 43 acres and has a normal storage capacity of 311 acre-feet, providing essential water storage for the community and supporting the ecological health of the region.

Despite being a local project, Bennington Lake Basin 1 is regulated by the state and has undergone regular inspections and enforcement measures to ensure its safety and functionality. With a maximum discharge capacity of 5300 cubic feet per second, this dam is a key component of the water infrastructure in the area, contributing to the overall resilience of the region in the face of changing climate patterns and water resource management challenges.
