Well, I guess the limestone didn't do what I intended it to do. After 2 days of torrential rains ( that's the only kind we get here in La. ) the pond is full of debris. The whole surface of the water is covered. The rip-rap did solve the erosion problem on the end of the pond, but the #4(that's the size they put alond railroad tracks) didn't stop the debris. It rained so hard that it completely washed the limestone into the pond in some areas. So I guess I spent $ 1,300.00 for nothing, and I still have to go home and try to skim the debris off the pond. If anyone has any suggestions I sure would appreciate it.
