Pike River, located in Tower, Minnesota, is a gravity dam completed in 1912 primarily for recreational purposes. With a height of 22 feet and a length of 250 feet, this dam has a significant hazard potential and is currently assessed to be in poor condition. Despite its age, Pike River continues to be regulated by the Minnesota Department of Natural Resources (MNDNR EWR), with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.

The dam has a storage capacity of 3,254 acre-feet and serves the surrounding area with a normal storage level of 2,049 acre-feet. The drainage area for Pike River is 185 square miles, with a maximum discharge capacity of 3,570 cubic feet per second. While the dam has not been modified in recent years, it remains a key feature in the region's water resource management. The last inspection in August 2019 highlighted the need for ongoing monitoring and maintenance to address safety concerns and prevent potential risks associated with its condition.

Overall, Pike River represents a historical and recreational landmark in St. Louis County, Minnesota, attracting water resource and climate enthusiasts alike. As efforts continue to ensure the dam's integrity and safety, it serves as a reminder of the importance of proactive management and maintenance of water infrastructure to safeguard communities and the environment for generations to come.
