C. Alex Harvin III Landing is a public Lake Marion boat-launch and fishing-access site on SC-260 near Manning, South Carolina. SCDNR’s official access data identifies the landing, and the agency scheduled a courtesy safety inspection there on July 4, 2026—current confirmation that the public landing remains in active use. This guide covers the verified approach, parking and accessibility information, Lake Marion hazards, fishing rules and the checks worth making before towing a boat to the ramp.

Getting there from SC-260

The landing’s listed address is 10421 SC-260, Manning, SC 29102. Navigation services may shorten the name to Alex Harvin Landing. Search for the full name or use the address rather than following an unverified lakeshore pin.

SC-260 is a two-lane state highway near the lake. Slow before the entrance, signal early and keep the travel lane clear while checking the turn. The final map is centered on the destination address, but current entrance signs and on-site traffic patterns take priority over the map.

Parking, accessibility and ramp checks

The Santee Cooper Country destination directory marks the site with accessible parking and an accessible entrance. It does not provide measured grades, cross-slopes, transfer systems or an accessibility assessment for the water’s edge. Visitors who need a specific accommodation should verify the current route from the parking area to the launch or fishing access before traveling.

Official sources reviewed for this guide do not confirm a restroom, drinking water, lighting, launch fee, overnight-parking policy, number of ramp lanes, courtesy-dock condition or current trailer capacity. Arrive self-contained and read every posted notice. Before backing down:

• Walk the launch and inspect for algae, mud, debris, damage and changing water depth.
• Prepare plugs, straps, lines and required safety equipment away from the active lane.
• Use a spotter and keep passengers clear of the vehicle path.
• Secure the vehicle in a marked space without blocking turnaround room or emergency access.
• Do not assume an empty lot means overnight parking is permitted.

Lake Marion conditions shape every launch

SCDNR publishes two acreage figures on the same Lake Marion page: its description calls the lake 110,600 acres, while the general-information table lists 90,000 acres of surface water. That table also reports 511 miles of shoreline, an average depth of 13.12 feet and a maximum depth of approximately 76.77 feet. The agency’s own acreage difference is worth recognizing, but either figure describes an expansive reservoir where shallow water makes route planning more important than the simple distance visible across the lake.

Much of the original woody debris remains valuable fish habitat, but it is also a navigation concern. SCDNR says navigational aids have been installed and specifically urges caution when traveling on Lake Marion. Santee Cooper warns that changing water levels can hide objects even in familiar areas.

• Follow marked navigation routes and never treat open-looking water as obstruction-free.
• Reduce speed near shore, timber, vegetation, shallow flats and unfamiliar coves.
• Check wind and thunderstorms before leaving the ramp; a long fetch can build rough water quickly.
• Review current lake and stream data or call 800-92-LAKES before a low-water or high-water trip.
• Carry a paper or offline lake map, a charged phone and enough fuel to return without relying on a shortcut.

Fishing around the landing

Lake Marion’s woody cover supports crappie, bream and catfish, while native aquatic vegetation provides habitat for largemouth bass, pickerel and other species. The Santee Cooper system also has striped bass and blue and flathead catfish fisheries. Those lake-wide facts do not guarantee a catch at the landing; water temperature, level, current, weather and angling pressure all matter.

Anglers age 16 or older generally need a valid South Carolina freshwater fishing license. Youth exemptions do not cover commercial activity or the use of regulated nongame-fish devices. Check the 2026–2027 South Carolina regulations before fishing because species limits, methods and device permits can differ. The safest approach is to identify the fish before keeping it and use the current rule, not an older Lake Marion summary.

SCDNR’s public-access map identifies this location as both a boat launch and fishing access. Stay within the designated public area, keep the launch lane clear, and do not cast across active boat traffic. If a pier, bank section or part of the shoreline is posted closed, use another legal access point.

Boat-safety rules to check before arrival

South Carolina requires appropriate safety equipment and boat registration. SCDNR’s June 29, 2026 notice scheduled a courtesy inspection at Alex Harvin Landing for July 4, covering required safety equipment and proper boat and motor registrations. The inspection date has passed, but the checklist remains a useful pre-launch standard.

• Carry a properly sized, U.S. Coast Guard-approved personal flotation device for everyone aboard.
• Confirm the throwable flotation device, sound device, fire extinguisher, navigation lights and visual distress signals required for your vessel and operating area.
• Anyone born after July 1, 2007, must complete an approved boating-safety course before operating a motorboat or personal watercraft of 10 horsepower or more, unless an exemption applies.
• File a float plan and tell someone your launch, route and expected return time.
• Use a sober operator and stay within the boat’s capacity limits.

Seasonal planning and aquatic plants

Late summer around Lake Marion can bring heat, intense sun, sudden thunderstorms and tropical-weather impacts. Launch early when conditions support it, carry more drinking water than expected, and leave the lake before lightning or strong winds reach the area. Recheck forecasts immediately before departure.

Santee Cooper manages invasive and nuisance aquatic plants including hydrilla, water hyacinth, giant salvinia and crested floating heart. Vegetation can collect near shallow access points and change quickly. Inspect the propeller, trailer, bunks, axle, livewell and fishing gear before leaving; remove visible plants and drain water where legal. Report significant nuisance vegetation through Santee Cooper’s aquatic-plant program.

What to verify on the day of your trip

• Landing entrance and parking availability
• Posted hours, fees and any temporary closures
• Ramp surface, water depth and dock or pier condition
• Lake level, wind, thunderstorms and tropical advisories
• Required boating equipment and registration
• Current fishing license, size, creel and method rules
• Any algae, aquatic-plant or water-quality notices

Nearby Lake Marion alternatives

• Santee State Park is a useful next option when developed park facilities, multiple ramps and a fishing pier matter more than a single public landing.
• Pack’s Landing can help boaters planning around on-site bait, fuel, food and access to the Lake Marion Passage.
