Did you get a soil analysis of your pond bottom? That would provide important info including how much lime to add . When applying lime the more of the pond bottom that you can apply it to the better. Some people have it done by barge or boat when the lake is full. There are pond management companies that offer this service. Others have it done by spreader truck when the lake is down and somtimes by the same method when full. If you are not going to have it done by boat then it is easier to cover a larger % of the bottom by spreader truck when the water is down. After you cover as much of the bottom as you can you may want to put more lime at the point where the water comes into the pond. The least effective way is to just dump it in the pond at one place when the pond is full.I hope this helps. ewest
