My part of the world has had a similar shortage of rainfall. One of the big lakes southeast of me (Cumberland) had to be drawn down for repairs to the dam earlier this year, and between that and less water entering it, they are finding all sorts of stuff that had been thought lost...

I've had to stay away from my nearby lake--too depressing to try to kayak with the water level down 18" from the usual.

The climate is changing--that much is certain (to me, at least). Whether humans accelerated the change is less certain. In any case, we are in for some rough times.
