Just joined this forum and you all have some great answers to diferent problems. I just bought a new home on 3 acres of land and my wife and I want ot put in a 50' x 50'(might be able to go 60' x 60') fishing pond. The soil is half dirt and half clay and holds water in a 3 ft hole I dug for about 3 hrs. I cannot go bigger than what I listed because of wooded property. I have a corn field from a farm about 150' from where I want to put the pond in and don't know if runoff from manure will hurt the pond water. Would like to stock the pond with smb and perch but is the pond big enough to do so?
