Alligator,
Take it from me, the very best way to lime is to call the local feed store or coop that does pasture liming and schedule them out to spread the lime in and around the drainage of the pond. This way is completely easy, totally effective and long lasting. Do not fool with the expensive barges and jury rigged methods of spreading lime into your water...it is a waste of time and money. Get a lime truck out and spread whatever number of tons you need and then forget about it for many years. Do it now, while your water level is down. You won't regret it.
