If you have the vest type inflatable you can remove it. If you have the belt type you must wear it at all times. Or have regular jacket in the boat. Really don’t know size and number limits do think they changed a year or so ago.

The 12-inch length limit does not apply to the reservoir spillway, but the spillway, including Sardis Lower Lake, has a 15 crappie creel limit.
Just pulled this off the net.
