The Minnesota DNR calls the proposed dam a “high hazard dam,” where failure is likely to cause loss of life. So, now the plan is to dig clay out of a diversion channel, and build a 15-foot-high dam from Comstock to Horace, and expect to provide protection for the metro area. But the problem is the clay under our black topsoil is expansive clay, which means it’s capable of absorbing large amounts of water. The more water it absorbs, the weaker it becomes. When it dries, it contracts and shrinks in size.
