George H Sparks Reservoir is a 215-acre lake within Sweetwater Creek State Park, located minutes from downtown Atlanta. The reservoir offers a controlled paddling environment where gas-powered motors are not permitted, eliminating concerns about boat wakes.

Paddlers can access the reservoir through the state park's facilities, where canoes, kayaks, stand-up paddleboards, and pedal boats are available for rent during warmer months. Two public boat launches serve the lake. A seasonal bait shop near the water provides basic amenities.

The water appears somewhat turbid, though the park maintains clean shorelines. Swimming is not permitted in the reservoir. While exploring the rambling shoreline, paddlers can observe diverse wildlife including bald eagles, ospreys, great blue herons, ducks, and geese. Several beaver dams can be found along the quieter sections of the lake.

One notable paddling route includes passage through an underpass tunnel that leads to a distinct ecosystem characterized by calmer waters and taller grasses. This section offers some of the best wildlife viewing opportunities. The reservoir is occasionally drained for archaeological studies, which have revealed Native American artifacts.

The lake is surrounded by hiking trails and features ten yurts overlooking the water. The park offers guided paddling tours and introductory paddling classes for newcomers. More experienced paddlers can participate in the Park Paddlers Club, which incorporates this reservoir into a broader challenge of paddling at six Georgia state parks.

A daily parking fee of $5 applies to all visitors. The park is open from 7 a.m. until dark, with reduced hours for the office and bait shop. Annual passes are available for frequent visitors.
