I just found the site yesterday and it looks very informative. I live in a developement in Mesa,AZ. We have 8 lakes/ponds. I live across the street from the largest, 36 acres. The max depth is 8'. There is approx. a 18" wall all around it,the lake is surrounded by homes. It contains Bass, Carp, Catfish, Crappie, Bluegill and Tilapia. The Bass are 1-2lb primarily, but I did catch a 4+. Rarely do I see or catch bluegill or Crappie, but the Crappie are 9-10" There is virtually no structure, except for a few areas of concrete from original construction. Very little habitat, we are installing some. Has docks with pontoon boats for cover. Grass, slop bottom. I think it would make a fantastic fishery. I would like to know how many fish we currently have per acre, species, how to improve growth rates and numbers etc. How would you "experienced ponders" approach this problem?
