Jones Dam 1620, located in Nuckolls, Nebraska, is a privately owned earth dam designed by USDA NRCS with a primary purpose of irrigation. Completed in 1975, this dam stands at a height of 22 feet and has a storage capacity of 170 acre-feet. Despite its low hazard potential, the dam is currently in poor condition and requires attention to ensure its continued functionality and safety.

Managed by the Nebraska Department of Natural Resources, Jones Dam 1620 is regulated, permitted, inspected, and enforced by state authorities. Situated on the TR-Little Blue River, this dam plays a crucial role in water resource management for the region. With a drainage area of 1.2 square miles and a maximum discharge of 596 cubic feet per second, the dam provides essential irrigation water for agricultural activities in the area.

Although the dam has not been modified in recent years, its condition assessment in 2020 revealed poor maintenance status. With a regular inspection frequency of 5 years, it is imperative to address the dam's structural issues promptly to prevent any potential risks or hazards. As water resource and climate enthusiasts, ensuring the proper maintenance and functionality of dams like Jones Dam 1620 is essential for sustainable water management and environmental conservation efforts in the region.
