Mack Pond, also known as Limestone 11, is a private water resource located in Taunton, Minnesota. Managed by AREA II and NRCS, this earth dam structure was completed in 1958 to primarily serve as a fire protection, stock, or small fish pond. The pond has a hydraulic height of 13 feet and a total height of 24 feet, with a storage capacity of 53 acre-feet and a drainage area of 1.3 square miles.

Owned and regulated by the state of Minnesota, Mack Pond is under the jurisdiction of the MNDNR EWR agency. With a low hazard potential and a satisfactory condition assessment, the dam has an uncontrolled spillway system and outlet gates. While the structure has not been modified in recent years, it underwent its last inspection in March 2016 and is scheduled for inspections every 8 years. The risk assessment for Mack Pond is moderate, indicating the need for continued monitoring and potential risk management measures in the future.

Overall, Mack Pond serves multiple purposes and provides essential services to the local community, including fire protection and water storage for livestock. Its location along the Yellow Medicine River-TR and its proximity to the city of Taunton make it a vital resource for the surrounding area. With a history dating back to the late 1950s, Mack Pond stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions.
