The Dells is about 20 minutes away from me, that was a pretty crazy time for this area. We had 10-12 inches of rain in 2 days and there was some pretty good flooding almost everywhere. Our basement even got flooded and because we weren't in a "flood basin" we couldn't get anything from our homeowner's insurance. But the system does work once in a while and FEMA covered our new water heater and funace.
Anyway, back to the Dells dam. I guess that they didn't open it up an more than normal throughout the weekend that we had all that rain. The ground was so saturated that it finally gave at the weakest point and washed a road and some houses out, the dam never gave. I have some pictures of the area and the empty lake around somewhere, I'll see if I can dig them up.
