Lake Retaining Wall

I've never used one before but excavata was told he would be the best way to dredge the mud at the edge of my dock area.I was also told that if I did it myself owner that the lac mgmt do not ask me to stop even if I was "caught" without lawful to make mgmt it.Lake also told me it would cost over 10k and costs of waiting 6 months to get the same permit. Im not trying to dig too far or too deep. Property is 30 years and had not a retaining wall before I there.You can imagine how much mud is in him (3 or 4 feet deep) as this is only of approximately 20 feet of waterfront. The dilemma is that I built a bridge over the retaining wall which is about 10 feet in width and length of the seafront So whatever excavata I use to be able to reach more than 10 feet before starting to dig down, maybe 6-8 feet under the bridge and as far as possible. possibly a smaller machine and a small bucket (less attention in this way, and easy to use

Forgive me Mac, but did you ever see that one of them can do things in the kitchen of a rabbit. It is not pretty Doc.

If I were you, I would take the phone to call a landscape design, or a crew of sanitation yard and let them do. You would not have to worry about not having work the way you want it that way. Just tell them what you want and let them do it. Some have done things that way before.
Good luck!
