You go to the doctor to get a health checkup, but the fish in our lakes can't. That's why the Tennessee Valley Authority went on Lake Guntersville to give those fish a checkup.

On Tuesday, TVA fisheries biologists hit Lake Guntersville near the dam checking for two things. One is the overall health of the fish population. The second is the health of the invertebrates living on the bottom of the lake.

One big question revolves around the bass population. For the first time in many years, Bassmasters has ranked Lake Guntersville out of the top five at number six.

In 2012, the lake was ranked third.

Some suggest that the popularity of the lake has caused a stressed population. But some TVA fisheries biologists feel fish populations cycle and Mother Nature can resolve it with a good spawning season.

“Had a little bit of a bump in 2011 with a pretty big recruitment there. Hopefully, this year bass tend to do well in real hot dry weather so hopefully next spring we'll see the results of the spawn and recruitment to age one from this summer,” said TVA fisheries biologist Kurt Lakin.

TVA officials say they'll take the data they find back where they can do trending analysis.
