Here's and overview of upper Limestone.
When the water is up it all looks the same, but when viewed at Winter pool with the water down five feet you'll quickly see the areas we discuss. I've marked the three main "pits", the Limestone Creek channel that always has some level of current and the old Limestone Creek channel that only has water moving when flow is high after a rain event. There are numerous other pits that only connect when the area is flooded that also have fish. This area always holds Crappie year-round except Dec - Feb when the water is at low pool and in the mid 40's and colder.
