The best thing to do is get a soil sample to determine how much lime you need. I put some lime in a pond where the only open area is the dam by using a boat and got two people who really wanted to fish help put in lime. I had one man on one side of the boat cut the bag open just enough for a small stream of lime to come out and the other man do the same on the other side of the boat and I drove around about 5000 times until the whole pond was covered.
