Several earlier posts last year described the construction of my 1 acre pond. It is about full (down 1 foot from overflow pipe). I will be renting a miniexcavator for some work on the pier/beach area, and now I'm thinking about also adding a small pool above the pond. This image shows what I have in mind. It would be about 20 feet diameter with a small spillway at the end of the ditch as it enters the pond. The purpose of this pool would be to serve as a sort of 4 foot deep refuge for frogs, crawfish, etc where the large bass would not get to them. Not sure how to train the little critters to stay in the safety zone. smile This image shows what I have in mind. It is based on an aerial photo taken before the pond filled. The red outline is just where I am planting grass. The blue outline shows the wet weather branch and the proposed additional pool.

This shows the current view and proposed pool from the east side.

Does this seem like a reasonable idea. Or would it likely just become a mosquito-infested swamp? And is such a project too much for a miniexcavator (Gehl 383)? The Gehl rents for $210/day. The rental company does have a larger Hitachi 120, which rents for $400/day.
