Conestoga Dam, also known as Conestoga Lake, is a federal-owned structure located in Lancaster County, Nebraska. Completed in 1964 by the US Army Corps of Engineers, this earth dam stands at a height of 65 feet along Holmes Creek, serving primarily for flood risk reduction. With a storage capacity of 15,000 acre-feet and a surface area of 230 acres, the dam plays a crucial role in managing water levels and mitigating potential risks associated with severe weather events.

Managed and funded by the US Army Corps of Engineers, Conestoga Dam is equipped with an uncontrolled spillway and operates under a high hazard potential classification. Regular inspections, emergency action plans, and risk management measures are in place to ensure the dam's structural integrity and the safety of surrounding communities. The dam also supports fish and wildlife habitats, along with recreational activities, making it a multifunctional resource for both humans and the environment. As climate change continues to impact water resources, Conestoga Dam remains a vital piece of infrastructure for safeguarding against flooding and maintaining sustainable water management practices in the region.
