Booking a boat on this lake is not like booking one on the coast. A few things are specific to here.
Ask for the current lake elevation. It determines whether the shallow arms are worth exploring and how much stump hazard there is. Staff will tell you plainly.
Ask what is included. Fuel is usually not. Neither, often, are tubes, skis or a cooler. Budget for fuel separately and expect to settle it on return.
Ask about the safety certificate. Georgia requires a boating education certificate for operators born on or after a certain date to run a powered vessel, and rental operators handle this in different ways, including temporary certification. Sort it before the morning of, not at the counter.
Book ahead for summer weekends and for October. The rental fleet on a lake this size is finite, and a single warm Saturday clears it.
Take more than you think. There is nowhere to buy anything on the water. No shop, no fuel dock in the far arms, no ice. Load in town.
Life jackets are not optional for children, and the rules are set by the state. The operator will supply them; make sure they fit before you leave the dock rather than a mile out.
