You'll need somebody you can really trust if you aren't able to be there the entire process.
What type of overflow/spillway? Of all the types i've seen, I like the siphon drain the best. It doesn't go thru the bottom of the dam. Seems like most ponds end up having troubles with their pipe years down the road. If it isn't at the bottom, you won't lose the whole pond fixing it.
Start planning out all your habitat, docks, spawning structure, etc. Its alot easier to place before the water is in. It takes a suprising amount of time/work to have that stuff ready to go. Does this dirt mover get into doing different things with the pond bottom like trenches, mounds, etc.
