Well, figured I would jump in here again.
With the ground as dry as it was, all that rain went straight to the ditches, into the creeks, and into the lake. So just a little rain brought our lake up a bunch!
On a positive note, they finally opened our boat launches up again yesterday.
Here is the site the keeps track of our water depth.

Note that each time it rains, even if only a 1/4", 1/2" or a full inch, the water comes up for about 3 or 5 days straight afterwards as it makes its way to the lake. The last rain we got was on 11/27, and look at how much the water has come up since then (7/10 of a FOOT!) and that was with .93" of rain.
We have only had about 4" of rain since the summer, and yet the lake has come up 4.9 FEET, just over the past month and a half or so.
Here is a pic from mid-september compared to day before yesterday...
