Banded Watersnake

Snapshot

The banded (southern) watersnake is a medium, heavy-bodied Coastal Plain watersnake with dark crossbands that are broad on the back and narrower on the sides — rectangular, not copperhead hourglasses. Older adults may darken until the pattern nearly vanishes. Common in nearly all freshwater habitats of the Georgia Coastal Plain. Non-venomous and protected; often misidentified as cottonmouth or copperhead.

Description and identification

SREL: about 24–48 inches. Color variable — light brown, reddish, or nearly black — with darker crossbands broad across the back and narrower on the sides. Unlike copperhead hourglasses, bands are more rectangular. Older snakes often darken; some look nearly uniform. Squarish belly spots; dark facial stripe from eye to corner of jaw. Keeled scales; divided anal plate.

Look-alikes

Copperheads have hourglass / Hershey-Kiss bands widest on the sides; banded watersnakes’ crossbands are more rectangular and widest on the back. Cottonmouths (Agkistrodon) share thick bodies and waterside habits but are pit vipers: heat-sensing pits between eye and nostril, generally more triangular heads, elliptical pupils in bright light, and (in adults) a different banding habit than Nerodia rectangles. Banded watersnakes lack pits, often climb onto logs and brush over water, and may darken with age until pattern nearly vanishes — dark older adults are the ones most often labeled “moccasin” at a glance. Northern watersnake replaces this species inland (Piedmont/mountains). When unsure near Coastal Plain water, leave alone either way — calm distance protects both people and harmless Nerodia.

Range in Georgia

U.S. Coastal Plain from southwest Alabama to North Carolina. In Georgia/South Carolina: Coastal Plain only, replaced inland by northern watersnake (N. sipedon). Full native range follows the southeastern Coastal Plain — broader than Georgia alone.

Habitat preferences

Nearly all freshwater habitats: ponds, lakes, rivers, streams, swamps, wetlands, and marshes.

Natural history

Active day and night; bask on logs or overhanging branches; forage in shallows. Viviparous; litters about 15–20 in late July or August. Like other watersnakes, they may flatten the body and strike if cornered, and can musk — defensive theater, not venom.

Food preferences

Primarily fish and amphibians.

Temperament and encounters

Frequently seen near water on the Coastal Plain. Non-venomous but will defend if grabbed. Leave alone; enjoy from a dock or trail. Dark older adults with faded bands are still watersnakes — pattern loss with age is normal, not proof of a pit viper.

Conservation and legal notes

Common through much of its Coastal Plain range; legally protected across Georgia.

In Georgia, non-venomous snakes are protected nongame wildlife. Per Georgia DNR materials summarizing O.C.G.A. §27-1-28, it is illegal (a misdemeanor punishable by up to a $1,000 fine and a year in jail) to possess or kill many nongame wildlife species, including non-venomous snakes. It is also illegal to disturb or destroy dens, holes, or homes of wildlife (O.C.G.A. §27-1-30). DNR emphasizes ecological value; needless killing of watersnakes mistaken for cottonmouths remains a serious problem. Report what DNR states; do not invent statutes or exceptions.

Georgia DNR’s georgiasnakes overview notes that among native snakes discussed there, only the eastern indigo and southern hognose are state-listed as threatened (indigo is also federally threatened). Educational ID — especially watersnakes vs cottonmouths — is conservation work.

If you meet one

Give the snake room. Identify from a distance; do not handle, poke, or try to kill it. Most encounters end when people simply step back. If relocation is truly needed, Georgia DNR points residents to private wildlife-removal specialists. Local educators — including community resources around Cartersville such as Etowah Valley Exotics when appropriate — can help with distant photo ID and outreach.

This species is not venomous. A defensive bite can still be painful — clean the wound and seek medical advice if needed — but it is not a pit-viper or coral-snake emergency. Leave wild snakes alone. Never pour gasoline or chemicals into holes (illegal under Georgia wildlife den-protection rules).
