I can't hardly believe a 650 acre lake would have any "stunted" bass in only 3 years. One of the best fishing lakes in Missouri was "stocked" by adding fish to farm ponds that would be flooded a couple years before the dam was completed.
I would make darn sure you get WRITTEN permission to release anything into public waters or the golf course ponds, or you'll almost certainly get a very unwanted education of the legal system.
If I'm going to take the effort, time and money all my ducks will be in a line before releasing anything into any body of water that I do not own.
As for the "stunted" bass, I'm going to be fishing the lake soon, so hopefully I can get a grasp on the fish size & numbers. I'm jumping to the conclusion that it's stunted because every person that fishes the golf course & lake has said the same thing.. No bass and very high crappie & chain pickerel numbers. Even one of my buddies that fishes the collegiate B.A.S.S tour and has won several large tournaments has been skunked 3/3 trips. Is that an accurate way to determine bass numbers? Of course not, but it definitely says something.
Unfortunately I do not have the time or resources to gather up an electro-fishing boat nor do I have any "pull" to convince our city council to do so..
