Blowers Dam, located in Grasston, Minnesota, is a privately owned structure managed by the USDA NRCS. Built in 1967, this earth dam on the Ann River serves primarily as a Fish and Wildlife Pond, with a storage capacity of 619 acre-feet and a surface area of 69 acres. The dam stands at a height of 10 feet and stretches 600 feet in length, providing vital support for the surrounding ecosystem.

Managed by the Minnesota Department of Natural Resources, Blowers Dam is regulated, inspected, and enforced to ensure its safety and functionality. With a low hazard potential and a satisfactory condition assessment, the dam poses moderate risk and is equipped with uncontrolled spillways and outlet gates. Although last inspected in 2016, the dam continues to meet regulatory guidelines and plays a crucial role in water resource management in Kanabec County.

For water resource and climate enthusiasts, Blowers Dam is not just a structure but a key component of the local landscape. Its presence supports fish and wildlife habitats, regulates water flow on the Ann River, and contributes to the overall ecological health of the region. As efforts continue to maintain and monitor this essential dam, its significance in sustaining the natural environment remains paramount for both current and future generations.
