The upstream boat barrier at the Rapidan Dam failed due to high water flow and passing debris on Saturday.

Blue Earth County officials say because the boat barrier is removed in the in the fall in preparation for winter it may not be repaired and back in place until spring.

The absence of the boat barrier creates an enhanced risk to anyone accessing the Blue Earth River upstream of the dam, and Sheriff’s Captain Paul Barta is asking people to avoid the upstream area of the dam for their own safety.
