Our pond was sprayed with Sonar last Wednesday. I note on the label that it is to be used in a body of water with no or very low water flow. Last Monday we had a major storm that lasted for hours. The rain was extremely heavy, and since the ground is already saturated it went as run off. We had floods all over.

The 6 inch discharge pipe on our .4 acre pond would have been running at near full capacity. Since the water was already near the top of that inlet it would have started running very quickly. It is still running now. What can be expected with the Sonar concentration?
