With a storage capacity of 54 acre-feet and a surface area of 2.9 acres, the dam serves to control water flow and prevent erosion in the Tr- East Fork Grand River.

Managed by the local government and regulated by the Iowa DNR, East Fork Grand River Watershed Site A-64 is characterized by a low hazard potential and a moderate risk assessment. While the dam's condition assessment is currently listed as "Not Rated," its risk management measures and emergency action plan status are not specified. Despite its relatively small drainage area of 0.16 square miles, the dam plays a crucial role in maintaining the stability of the East Fork Grand River watershed and mitigating potential flood risks in the region.
