One of the lakes I visit frequently has dropped drastically. The foot bridge in this first photo crosses one end of the lake. The water is normally within a foot or less of the bridge deck. You can see old water lines on the pillars. Right now you can skip the bridge and just walk across the lake bed.

The water line on this cypress tree is obvious and you can see just how much the lake level has dropped. Normally, you wouldn't be able to walk out to the tree.
