Here’s someone’s drone footage of some of the flooding in Garland:
Garland Shooting Range Flooding 3:30pm on 11/27/2015
At about :32 seconds, on the right side of the road, where there’s a thin gap between the trees, is a creek. The creek is only about a third of the width separating the trees.
At about :40, on the left, is the blue roof of a gun range. On the right is a field. There’s no lake or pond or any kind of water behind the gun range. It’s just all flooding.
