Crappie are such prolific spawners that you shouldn't worry. For the longest time there were just too many in there resulting in a small overall size. It's been probably 7 years or more since I've fished Taylorsville, but when I did fish it there was no shortage of crappie under 9", there were some days I'd run out of minnows long before I had a limit of keepers.

KDFWR fisheries biologists know what they're doing, they've spent many years learning and studying fisheries management long before getting the job. With their continued monitoring and adjustments of minimum size length and creel limits based on what the fishery can support, you shouldn't worry.
