When the dam broke and drained Mirror Pond, we all looked at the dry riverbed. The pond drained and the solution appeared. Dry dredge Mirror Pond. Drain it, dredge it dry and then fix the dam. Dry dredge is cheap, easy and fast. We were thinking we could only wet dredge, which is expensive and takes lots of time. I say this winter, we drain Mirror Pond, do the dry dredge and then fill it back up in the summer.
