I live near a city lake that is approximately 600 acres. The lake was becoming too shallow and something had to be done to make it deeper. They found a land owner that was willing to be paid for having his land covered in the sludge. He didn't live nearby, so pipes were laid for transportation of the unwanted earth. I haven't heard what effect the action has had on his land, but you may want to consider that aspect of it. Will the pond mud change the make up of soil that you combine it with? Will it affect plant life, trees, etc. adversly?

I really think you are looking at a very expensive process to dredge an 8 acre pond. Check your topo map and see if you can build a new lake somewhere else on the property. Make it the deep lake for ice fishing.
