I used James Robertson custom dozing out of Knob Noster Mo. They did a fantastic job and he was very reasonably priced,you are more than welcome to come out and check his work here in Holden if you like. He keeps you well informed with the project. He built my pond which is 22 ft deep at the basin, and I had them cut a 10 ft wide 5 ft deep channel down the middle, 1 1/4 acre, cost was $12600.
