Whether you’re cruising for fun, heading out to fish, or just enjoying a relaxing day on the water, understanding Lake Hartwell’s buoy system is essential for safe and confident boating. Lake Hartwell is a vast and beautiful reservoir, and its network of buoys and channel markers acts like road signs on the water, guiding you through channels, warning of hazards, and helping you stay oriented.
Here’s a quick guide to what the different colors and symbols mean:
Red & Green Channel Markers
Navigating upstream (generally northward on Lake Hartwell) means following a simple rule:
- Red buoys with even numbers mark the right side of the channel.
- Green buoys with odd numbers mark the left side of the channel.
TIP: Stay between the red and green buoys when navigating—areas between the buoys and the shoreline are often more shallow and may contain hidden hazards like stumps or rocks.
White Buoys with Red Vertical Bars
These mark the center of creek channels and the headwater areas of the Tugaloo and Seneca Rivers. They’re great indicators for staying centered in narrower areas.
Red & Green Junction Markers
When you reach the junction of a creek with the main channel, you’ll see red and green buoys stacked. The top color indicates the direction of the main channel, guiding your decision on which way to turn.
“S” and “T” Buoy Numbers
If you’re navigating up the Seneca River, the buoys are labeled with an “S”, and those on the Tugaloo River have a “T”. The numbers increase as you head upstream, helping you track your location and direction.
Special Buoys & What They Mean
- Orange Diamonds with Horizontal Orange Stripes: These hazard markers warn of potential dangers like shoals, rocks, or submerged trees. Navigate with extra care around these.
- No Wake Buoys: Located near boat ramps, marinas, and bridges, these indicate areas where you must operate at idle speed only.
- Boats Keep Out Buoys: Marked with an orange diamond and a plus sign (+), these designate restricted zones, such as areas near the dam or swimming areas.
Channel Marker Codes: A Quick Reference for Lake Hartwell
Each creek or branch on the lake is associated with a two- to four-letter code. These help identify specific areas, especially when used on maps or by local agencies:
| Creek Name | Code |
These channel marker codes, more formally known as Aids to Navigation, help boaters locate themselves and stay on safe paths, especially in less familiar areas.
