Same problem here in WNY, went from too much rain to nothing since mid-August. If it is going to be really dry, I would rather it be this time of year since the growing season is over, and like RAH says, a great time to build a pond. The winter is usually pretty good at coming along and filling things up after construction.

It is not good for fall colors though, the leaves are just drying up and falling off as soon as they turn. It has been quite hot up until today and it has backed the colored leaves to a crisp.

My pond is down 6" after being in overflow from January up to August. I was liking that nice full pool.

Have hope, the long-term weather models are predicting a "monsoon gyre" in the center of the Gulf, and those have a tendency of getting sucked up into the CONUS and wrung out. There is a decent chance you will be complaining about an overflow issue soon enough.
