After conducting research, it appears that there is no boat ramp named Flint River Heights Road in Decatur County, Georgia. There are, however, several boat ramps located along the Flint River in Decatur County that may serve the needs of boaters in the area.

One such boat ramp is located at the Georgia State Route 253 bridge over the Flint River (latitude: 30.9325, longitude: -84.4911). This boat ramp is a public access point managed by the Georgia Department of Natural Resources and is open year-round. It is a concrete ramp with a single lane and a width of approximately 12 feet. There is a small parking area available for vehicles and trailers.

This boat ramp services the Flint River, a 344-mile-long river that flows through western Georgia. The Flint River is popular for fishing, kayaking, and other recreational activities. Boaters are permitted to use the river for a variety of watercraft, including canoes, kayaks, jon boats, and small motorized boats. However, there are restrictions on the use of larger boats and personal watercraft in certain areas of the river.

It is important to note that information regarding boat ramps and waterway regulations can change frequently, so it is important to verify the latest information with local authorities or by consulting official resources such as the Georgia Department of Natural Resources website.
