I-Bass – 12 Mile Lake

Twelve Mile is a straight-up BIG BASS playground, and it’s built for anglers who love flipping wood one minute and dragging deeper structure the next. This Union County reservoir has a “tournament lake” feel from end to end—because it’s packed with cover, has legit depth, and it’s famous for putting out quality fish year after year.

What makes 12 Mile special is how much of it screams ambush water. The lake is loaded with trees/wood cover and shoreline targets that let bass set up and eat—perfect for anglers hunting that one violent bite that changes the whole day. Then, if you want to swing for a true kicker, Twelve Mile also offers deep-water opportunities with creek-channel breaks, points, and depth changes that set up perfectly for bigger fish when conditions line up.

And the best part for tournament energy? It’s a no-wake lake (no size limit at no-wake)—so instead of a “run fast, fish fast” event, it becomes a precision hunt for giants, where the anglers who manage their water, rotate the best trees, and time the deeper bite are the ones most likely to hoist a bag with a true BIG BASS in it.
