Located in Keya Paha, Nebraska, Peterson Dam 1 is a privately owned earth dam completed in 1965 primarily for recreational purposes. With a height of 24 feet and a length of 340 feet, the dam holds a storage capacity of 98 acre-feet and serves as a popular spot for water enthusiasts to enjoy activities such as fishing and boating on the South Branch Coon Creek.

Despite its low hazard potential, a poor condition assessment in 2016 raises concerns about the dam's long-term integrity. The dam is regulated by the Nebraska Department of Natural Resources and undergoes regular inspections, with the last one conducted in March 2016. While the dam's emergency action plan status and risk assessment measures remain unknown, the dam continues to be a key feature in the local landscape and water resource management.

With a drainage area of 0.8 square miles and a maximum discharge of 545 cubic feet per second, Peterson Dam 1 plays a crucial role in managing water flow in the area. As climate change continues to impact water resources, it is essential for stakeholders to prioritize maintenance and upgrades to ensure the dam's safety and sustainability for future generations of water and climate enthusiasts.
