I did find this on the MDC webiste
A: The Gasconade River is not ideal for Asian carp, nor for common carp, at any time of the year due to its fast flow rate, low fertility and clear water. The carps’ lower metabolism in the winter makes faster currents even less attractive. Several studies have shown that carp tend to move downstream in the fall and overwinter in deeper holes like the ones you find behind dikes or at the mouths of larger tributaries to the Missouri River. Carp in the lower Gasconade may leave that river each fall and become less active in deep holes in the Missouri River. Asian carp will remain more active during the winter than common carp.
