Boulder Lake Dike Ee, located in St. Louis County, Minnesota, was completed in 1919 and serves as a vital structure for hydroelectric power generation and recreation. This earth dam stands at a height of 20 feet and has a storage capacity of 30,300 acre-feet, providing a surface area of 4,100 acres for various water activities. The dam is regulated by the Federal Energy Regulatory Commission and is subject to state inspections, permitting, and enforcement to ensure its safety and functionality.

The dam is situated along Otter Creek and is associated with two other structures, collectively serving the purpose of water management and power generation. Despite being classified as low hazard potential, Boulder Lake Dike Ee undergoes regular inspections, with the last one conducted in September 2018. The dam is not under the jurisdiction of the US Army Corps of Engineers and does not have specific risk assessment or emergency action plans in place, highlighting the need for continued monitoring and maintenance to safeguard the surrounding environment and communities.

As water resource and climate enthusiasts, understanding the significance of Boulder Lake Dike Ee in the local ecosystem and energy production is crucial. With its historical construction and ongoing regulatory oversight, this dam symbolizes the delicate balance between human development and environmental preservation. By acknowledging its role in hydroelectric power generation and recreational opportunities, we can appreciate the complex interplay between water resources, infrastructure, and sustainable practices in the face of changing climates and evolving water management strategies.
