Greogory Dam, located in Iowa, was completed in 1959 by the USDA NRCS and is privately owned. This earth dam stands at a height of 21 feet and has a length of 598 feet, providing fire protection, stock, and small fish pond purposes. With a normal storage capacity of 64 acre-feet and a maximum storage of 100 acre-feet, the dam covers a surface area of 8.6 acres and drains an area of 0.37 square miles.

Managed by the Iowa DNR, Greogory Dam is regulated, permitted, inspected, and enforced by the state. Despite being rated as "Low" hazard potential and "Not Rated" in condition assessment, the dam poses a moderate risk. With a spillway type of "Uncontrolled" and no outlet gates, modifications or improvements have not been conducted since its last inspection in 1965. Overall, Greogory Dam serves as a vital resource for fire protection, stock, and small fish pond purposes in the Taylor County area.

Under the jurisdiction of the Kansas City District, Greogory Dam is situated on the TR-PLATTE RANCH river or stream. With Cindy Axne (D) as the local representative, the dam's risk is considered moderate and additional risk management measures may be necessary to ensure the safety and integrity of the structure. As a valuable water resource in the region, Greogory Dam plays a crucial role in providing essential services to the local community while also offering recreational opportunities for enthusiasts and climate advocates alike.
