I'm new here and this is my first post. I hope I'm in the right area. I am inquiring here about the cost to repair an old spillway on a 50 acre lake. This lake was formed by a dammed up creek many years ago and the cost of construction was paid for by a group of local outdoor enthusiasts. Unfortunately the contractor that build the dam made a mistake when building the spillway. Long story short the spillway is about 10 feet to low. The lake only fills to a level that essentially makes it a big swamp. The local group of sportsman that funded the project lost their investment when the contractor left them high and dry. I would like to raise money to rebuild this spillway and finally make this lake what those sportsman had dreamed of. Several of them are still around and I fish with them often. There are still hard feelings about the fiasco and they don't like to even talk about it. So I guess the question is approximately how much do you guys think it would cost to have a spillway raised?
