Constructed in 1937, this Earth dam stands at a height of 13 feet and has a hydraulic height of 10 feet, serving primarily for purposes other than flood control or water supply. With a storage capacity of 3,183 acre-feet and a drainage area of 44.8 square miles, the dam has a low hazard potential but a poor condition assessment as of the last inspection in July 2018.
Despite its poor condition, the dam continues to be regulated and inspected by the Michigan Department of Environment, Great Lakes, and Energy (DEGLE). The structure has undergone modifications in 1963 to improve its structural integrity. The risk assessment categorizes the dam as having very high risk, with measures in place to manage potential hazards. With its controlled spillway and outlet gates, Seney A-1 Pool Dam plays a crucial role in water management and conservation efforts in the region, making it a notable site for water resource and climate enthusiasts to explore and study.
