The Rapidan Dam in Blue Earth County, Minnesota, is currently in an imminent failure condition, causing concern among residents as water levels rise. Blue Earth County Emergency Management officials have issued alerts to notify individuals in the vicinity of the potential danger posed by the dam.
As of the latest update, the dam remains intact, and there is no evacuation order in place for Blue Earth County residents. The situation is being closely monitored by BEC Public Works, Emergency Management, and the Sheriff’s Office to ensure the safety of the community.
While the exact outcome is uncertain, officials have deemed it necessary to inform residents downstream of the dam about the situation. The water level at the dam currently stands at 28 feet, with the levee system designed to withstand river capacities up to 39.5 feet.
In the event of a dam failure, officials estimate a potential 2-foot surge in the river level. However, the City of Mankato reassures residents that the levee system is expected to hold, and there are no evacuation orders in place for any areas within the city.
Additional precautions are being taken, with Xcel Energy mobilizing resources to protect a nearby substation. Minnesota Governor Tim Walz, along with state emergency response officials, are actively monitoring the situation and coordinating with local authorities to ensure public safety.
Despite the ongoing concerns, the integrity of the dam remains intact at present. The National Weather Service has issued a Flash Flood Warning for Blue Earth County until 4:30 p.m. on Monday, prompting the closure of exit and entrance ramps on Highway 169 for the construction of an earthen dike to manage runoff effectively.
Efforts are underway to address the situation and safeguard the community from any potential risks associated with the dam's condition. Residents are advised to stay informed and follow guidance from local authorities as the situation continues to evolve.
