Notes:
Here's that small sinkhole that developed in the first storm. Didn't look too bad. Then came a second storm, and by April 2, we had a big problem. After the rains ended, as the water level dropped, it just got worse and worse. You can see, on April 5, what looked like little holes in the concrete spillway, but we sledgehammered the concrete veneer, and you get an idea of the depth of the cavern.
