Below is the email response I received today from TVA concerning why the water levels on Wheeler and Guntersville have been higher than normal for this time of year recently.

Hello. It is always nice to hear from you again.
Wheeler and Guntersville Reservoirs are only slightly above the guide curve for this time of year, mainly due
to the heavy rainfall amounts received over the last 30 days. Guntersville should be operating very closely
to elevation 594, and the elevation this morning (October 22) was 594.3. Wheeler is usually between 552
and 553 in October. The elevation this morning was 554.2 -- not high enough to cause concern.
The previous 30-day rainfall total below Chattanooga was 8.9 inches, as compared to a normal total of
approximately three inches, 297 percent of normal. Runoff was 1.8 inches, compared to a normal 0.4
inches, 450 percent of normal. Therefore, we have seen significant rain in the western region. Not only do
we have to contend with the rainfall received in the immediate vicinity of a reservoir, we must also consider
the impacts of those reservoirs which are downstream. By holding some of the runoff in the reservoir, we
can possibly alleviate some potential downstream flooding and/or the need to spill. After the threat of
flooding has past, we optimize the release of the water to reap the most economic benefits, keeping in
mind the potential for future heavy rains.
If we can be of further assistance, please contact us.

The levels on both lakes are starting to fall back to normal levels. Hopefully, this will get the fish biting a little bit better!
Good luck and good fishin'
