I am guessing the survey will cost at least $1,000. I talked with survey company and they have the capabilities in get in the water and measure these channels. They were never told about the channels being under the water by the contractors.

We love our pond. Its big and deep. We believe that they are ripping us off on dirt quantities that they took. The pond is almost 6 acres and approx 15ft deep to the floor and the channels are another 8+ft deep. I do not know how to do the math on that:)
