there is a limestone quarry in auburn al, which isn't too terribly far from you. i went there twice so far and picked up 4 or 5 tons on my dump trailer. you shouldn't need an awful lot for a 1 acre pond. can any type truck get to your pond? you might could get a local pasture fertilizing company to bring their spreader truck and sling it to one side. it would help. we usually just shovel it out of the trailer..lots of work.
