6 most snake-filled water bodies in South Carolina: From the Savannah River to the ACE Basin

South Carolina is a state built around water. From its coastal lowlands with their beaches and wetlands to the rivers and lakes spread throughout its forested landscape, the state abounds with bodies of water that offer opportunities such as fishing, boating, swimming, and camping. But along with the wildlife most visitors welcome, these waters also attract something far more divisive.South Carolina keeps many species of snakes, ranging from harmless non-venomous ones like the common water snake to the dangerous eastern copperhead.

South Carolina’s most snake-filled waters

Snake-filled rivers and lakes in South Carolina

1. Savannah River

The Savannah River is one of South Carolina’s major rivers, flowing from the Blue Ridge Mountains all the way to the Atlantic Ocean. It spans around 300 miles through South Carolina and Georgia, with multiple tributaries including the Seneca River.Among all the wildlife, snakes are very much present. The most common species in the adjacent Savannah National Wildlife Refuge are the timber rattlesnake, green water snakes.

2. Great Pee Dee River

The Great Pee Dee River flows through South Carolina. Stretching across forested wetlands and farmland, it has long been an essential waterway for trade, recreation, and wildlife.The banded water snake is the most notable species along the Pee Dee. The banded water snake is active during the day and night in aquatic habitats. However, they mostly rely on fish as their primary food source, diving into the water to hunt.

3. Congaree River

The Congaree River flows through the heart of the Congaree River and is the defining waterway of Congaree National Park. The park protects the largest intact expanse of old-growth bottomland hardwood forest remaining in the southeastern United States.The swampy floodplain shaped by the Congaree and Wateree Rivers creates the saturated soils, lakes, and sloughs that support high concentrations of water-based snakes. Species of snakes found are: black rat snake, rough green snake, red-bellied watersnake, black racer, Northern brown snake, and the Eastern cottonmouth.

4. Lake Murray

Lake Murray sits in central South Carolina and makes it one of the largest reservoirs in the region. The lake is also home to numerous islands, which offer undisturbed nesting sites, fewer predators, and plentiful birds and their eggs for snakes to feed on. Non-venomous species here include the eastern king snake, scarlet kingsnake, Southern black racer, scarlet snake , eastern coachwhip , rough green snake, eastern corn snake, eastern ribbon snake, and eastern garter snake.Venomous snake also found around Lake Murray, including the pygmy rattlesnake, timber rattlesnake, northern copperhead, and eastern cottonmouth.

5. Lake Hartwell

Lake Hartwell sits on the border between South Carolina and Georgia. It is one of the most well-known recreational lakes in the region. Most of the species here are venomous. Brown water snakes and northern water snakes are the most abundant. Watersnake, rat snake, Dekays brown snake, and ring neck snake are also commonly seen.

6. ACE Basin

It is located near the atlantic coast. These include the cottonmouth, red-bellied watersnake, banded watersnake, and brown watersnake. Eastern diamondbacks are strong swimmers in this region and are also known to enter saltwater to move between barrier islands along with the swamps.

Why South Carolina’s waters are so attractive to snakes

Snakes are cold-blooded animals that thrive in warm environments. South Carolina’s combination of warm rivers, extensive wetlands, sheltered shorelines, and abundant prey makes it one of the most snake-friendly states in the country. Most of the state’s native snake species are mostly harmless and genuinely beneficial to the ecosystems they live in.They serve as prey for birds while also being skilled predators themselves. Snakes also help reduce the spread of disease to humans by managing those same populations. The species that require real caution are the venomous ones: primarily the cottonmouth, the copperhead, and the rattlesnake, all of which can cause serious harm if disturbed.
