How to deal with a pond silting up I live in a town that has a sizable pond that is dammed with a concrete overfall spillway. Decades ago the state demanded that the dam be installed to guarantee that the surface height of the pond remain the same when a culvert was being built at the outfall of the pond.

This is a problem because the pond is slowly silting up, and as it silts up it is becoming larger and larger and shallower and shallower, basically it is slowly turning into a marsh which is infiltrating into people's backyards (not mine, but those of some neighbors).

How can this problem be solved?
That is what lakes and ponds do , fill with silt. Serious earth moving equipment is needed to slow Mother Nature. Our community has recently removed some silt with draglines, bulldozers , trucks , etc. I don't know the cost but certainly significant . They concentrated on certain areas to facilitate flow as we have a dammed stream that made roughly a 300 and 100 acre lake and the costs of general silt removal would be overwhelming.  On the upside , bushes on a new island have become a egret rookery,
