Pool level The "normal" band shows this lake's operating pool. Summer full pool 606′ and winter full pool 604′ are the operator's (USACE) published values. The low mark (602′) is a LakeStatus-defined "typical operating low," not a surveyed or official limit — it's our estimate of where shallow ramps start to get risky. The current level is live from the operator. This is context, not a guarantee; always confirm conditions before you launch.
Lake is 3.3 ft below full pool, within the normal operating band. "Below normal" means the lake is under our estimated typical operating low — a LakeStatus threshold, not an official or surveyed limit. We can't verify any individual ramp's depth from lake level alone, and usability depends on your boat's draft. Treat this as a prompt to confirm conditions, not a statement that a ramp is closed.
