Also, the last ice age ended 11,000 years ago, which is a long time to us humans but just a blink of an eye in geologic times. There are still fluctuations relating to that.
One also hears about the Great Lakes' water level dropping, but one of the factors in that is that the area is still rebounding from being covered by the ice sheets--something like 1/2 inch a year or so. (But don't quote me on that, I'd have to go look it up again.)
