I have 3 ponds that are divided by dams. They are fed by 90 acres of runoff. These ponds were built by my grandfather 60 years ago, and have filled with this pudding like sludge. The sludge is as deep as 6 feet in some spots. There is no real way of getting heavy equipment in to get it out of the biggest pond (4 acre ). Is there anything that I can do to remove this stuff? It is taking up to much volume that could be used for water.
