Welcome Travis! Got your PM, email me sometime happy to help phone is much easier. Starters: Need to know age of pond, species present, eutrophication level [muck buildup, water quality issues, etc.], species of vegetation present...anything invasive, trees on dam, muskrat/beaver issues, maximum depth and average depth of pond. Spend some time and map it all out and keep detailed records of all these items. Renovation may not be necessary, might be the best course of action, or instead invest the capital into building a new pond up or downstream. Lot's of options on 35 acres.
