The small town of Lanesboro, located in the heart of Bluff Country, is requesting $3 million in bonding to repair the Lanesboro Stone Dam. The dam sits on the popular Root River and was built in 1868 using a now obsolete method of un-mortared limestone – one of only six structures like it in the U.S.
This aging infrastructure is considered a ‘high hazard dam’ by the DNR, which means it does not meet the required factors of safety for stability, and its failure could cause the loss of human life.
The DNR is requesting $3 million to repair the dam – which sits on the National Register of Historic Places. It is because of this very designation that makes repairing the dam more difficult, because different techniques must be used to preserve its historic significance.
