This used to be a very, very small stream. Flat land.
Then we had 3.5 inches in Ivins where I live.
This little stream, turned into a raging river. Filled up a pond that had a dam in front of it. The dam broke and well, it flooded homes, businesses and caused a lot of damage. I took Tiah down there to explore and I couldn't believe how much the little stream changed.
