4 Most Snake-Infested Lakes in Alabama
Water snakes are common in Alabama lakes.

Alabama Lakes and Alabama Snakes:

  • Snake populations are difficult to track for numerous reasons. Their nocturnal and avoidant nature has only recently earned them the status of priority species for protection.
  • Many lakes in Alabama were formed as the result of a dam forming a reservoir. Therefore, habitats and ecosystems where many snakes lived were all condensed into edges of the reservoir, forming dense populations!
  • Water snakes call many lakes in Alabama home, and these aquatic serpents can often be more venomous than their land-dwelling relatives!

1. Lake Martin

The grand Lake Martin, formed by the construction of Martin Dam on the Tallapoosa River, stands as one of the largest man-made lakes in the United States. The lake’s varied ecosystem offers a suitable habitat for numerous snake species. Among the snakes found in and around Lake Martin are water snakes such as the cottonmouth (water moccasin), copperheads, and non-venomous water snakes. Furthermore, observers can also spot land snakes such as rat snakes and garter snakes. The cottonmouth, recognized by its venomous bite and distinctive white mouth lining, is the most common venomous snake in the area. While exploring Lake Martin’s picturesque shorelines, visitors may encounter these intriguing reptiles, contributing to a memorable experience in the heart of Alabama.
