Beattle Dam, located in Union County, Iowa, was completed in 1969 and is owned by a private entity. Designed by the USDA NRCS, this earth dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 32 feet and a length of 315 feet, the dam has a storage capacity of 34 acre-feet and covers a surface area of 2.6 acres. Situated on TR-Sugar Creek, the dam is regulated by the Iowa DNR and undergoes regular inspections and enforcement to ensure its safety and compliance with state regulations.

Despite being classified as having a low hazard potential, Beattle Dam poses moderate risks according to a risk assessment rating of 3. While the dam's condition assessment is currently listed as "Not Rated," it remains under the jurisdiction of the Iowa DNR for permitting, inspection, and enforcement purposes. The dam's spillway type is uncontrolled, and it does not have outlet gates or associated structures. Though lacking certain risk management measures and emergency action plans, Beattle Dam continues to play a crucial role in water resource management and ecosystem conservation efforts in the region, benefiting local wildlife and agriculture.
