Boller Pool, located in Minnesota City, Minnesota, is a privately owned earth dam designed by the USDA NRCS in 1970 for flood risk reduction along Rollingstone Creek. Standing at 30 feet tall and 537 feet long, this dam has a storage capacity of 125 acre-feet and a drainage area of 1.1 square miles. With a maximum discharge of 250 cubic feet per second and a low hazard potential, Boller Pool plays a crucial role in managing water flow and mitigating flood risks in the area.

Managed by the Minnesota Department of Natural Resources, Boller Pool is subject to state regulation, inspection, and enforcement to ensure its structural integrity and functionality. The dam, primarily designed for flood risk reduction, is classified as a buttress earth dam with uncontrolled spillways and outlet gates. A fair condition assessment in 2010 and moderate risk assessment indicate the need for ongoing monitoring and maintenance to uphold the dam's effectiveness in protecting the surrounding area from potential flooding events.

In the event of an emergency, the dam's emergency action plan and inundation maps are essential tools for risk management and coordination with relevant authorities. With a history of regular inspections and a designated inspection frequency of 8 years, Boller Pool remains a vital component of the local water resource infrastructure, demonstrating its importance in safeguarding the community against the impacts of climate variability and extreme weather events.
