First, thanks for all the responses for far!

Let me give you a little more information. The pond is on 1.5 acres, and the only place I have to dump the silt would be .5 acres behind my house. Since silt takes years to dry, wouldn't I lose the ability to walk in my back yard for years?

Also, if I take the silt out (it's on the north side), I would need to move dirt from the south side so I can have a shelf for fish to spawn. Does that sound right?

I know everyone likes to have a deep pond (and so do I), but this pond is only 1/3 acre. I want to put a bream and bass in there. Is it a good idea to go deep all the way in the pond? How deep is good enough?

And, is the general consensus to always remove silt, even if it means moving "new" dirt around for shelves?

thanks!
