With a primary purpose of fire protection, stock, or small fish pond, the dam has a storage capacity of 40 acre-feet and a drainage area of 0.64 square miles.

Despite being unregulated by the state, the De Frang Pooling Agreement poses a low hazard potential and has a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 60 feet and outlet gates that are also uncontrolled. The structure has not been inspected recently, and its condition is currently listed as "Not Rated," indicating that further assessment may be needed to ensure its continued safety and functionality.

Located in Wabasha County, Minnesota, the De Frang Pooling Agreement serves as a vital resource for fire protection and water storage in the area.
