Future of the Rapidan Dam
Project Overview
The Rapidan Dam was built over 100 years ago and has been managed by Blue Earth County for the last 46 years. Throughout the years, the dam has experienced regular flooding—the second-highest flood on record occurring as recently as 2019. These flood events and the toll of time have caused significant damage to the dam’s structure and usability.
In 2021, a study was conducted that identified two feasible solutions for the dam’s state of disrepair: repair or remove the dam. Both options have significant costs, and each has its opportunities, trade-offs, and timeframes. The purpose of the Future of Rapidan Dam project is to identify the community’s needs and concerns and use their input on the options to help the County make the best decision for all impacted by the Dam’s future.

The official Rapidan Dam survey period closed on June 30th, but we are still welcoming comments while the results are being analyzed. Your feedback is critical so the County Board can make the best decision for the future of the Rapidan Dam.
On Tuesday, August 16, 2022, Bolton & Menk presented a report on engagement efforts regarding the future of the Rapidan Dam.
