Missouri is a paradise for nature lovers, offering breathtaking landscapes, diverse wildlife, and numerous outdoor activities. The state is home to several picturesque lakes, including Rocky Falls, Montauk Springs, and Table Rock Lake, which attract thousands of visitors each year. However, while these waterside locations are perfect for swimming, boating, and hiking, they are also home to various snake species.
With over 45 different types of snakes in Missouri—five of which are venomous—it’s essential to be cautious when visiting lakes that serve as breeding grounds for these reptiles. This article explores the most snake-infested lakes in Missouri to help you stay informed and safe while enjoying the state’s natural beauty.
1. Smithville Lake
Located in Clay County, Smithville Lake was created in the late 1970s with the construction of the Smithville Dam on the Platte River. This lake is not only a popular destination for fishing and camping but also one of the most snake-populated bodies of water in Missouri.
The most common snake species found here is DeKay’s brown snake, which can grow up to 19 inches (49 cm) in length. While non-venomous, this snake can become aggressive if disturbed, so it’s best to avoid close encounters. Other snake species in the area include:
- Common Watersnake – Non-venomous but often mistaken for a venomous snake due to its aggressive nature.
- Garter Snake – A harmless snake that plays an essential role in controlling insect populations.
- Eastern Copperhead – One of Missouri’s venomous snakes, recognized by its distinctive copper-colored head and hourglass-shaped markings.
Visitors are advised to stay alert, especially near the water’s edge and wooded areas.
2. Table Rock Lake
Table Rock Lake is one of the most famous tourist spots in Missouri, stretching into Arkansas. Known for its clear waters and stunning surroundings, this lake is also home to several snake species.
Commonly spotted snakes at Table Rock Lake include:
- Ring-Necked Snake – A small, harmless snake with a bright orange or yellow ring around its neck.
- Western Rat Snake – A large, non-venomous snake that helps control rodent populations.
- Pygmy Rattlesnake – A venomous snake with a small but potent rattle.
- Common Watersnake – An excellent swimmer with brown or reddish scales and dark crossbands.
The common watersnake is particularly notable here. While not venomous, it is often mistaken for a cottonmouth due to its aggressive behavior. Some can grow up to 4 feet 5 inches (135 cm) in length. Though they pose no significant threat, maintaining a safe distance is always advisable.
3. Harry S. Truman Reservoir
The Harry S. Truman Reservoir is another scenic location in Missouri where visitors enjoy fishing, hiking, and camping. However, it is also known for its snake population.
Among the frequently encountered species here are:
- Common Watersnake – Often found along the shoreline and shallow areas.
- Western Rat Snake – Frequently seen climbing trees near the water.
- Prairie Kingsnake – A medium-sized, non-venomous snake that emits a rattling sound when threatened.
Although none of these species are venomous, they can be alarming to unsuspecting visitors. If you’re camping near the reservoir, it’s essential to check your surroundings before settling in.
4. Lake of the Ozarks
Nicknamed “The Missouri Dragon” for its winding shape, Lake of the Ozarks is one of the most popular lakes in the state. Unfortunately, it is also home to numerous snakes.
Some of the most common species found here include:
- Common Watersnake – Abundant in the lake’s shallow waters.
- Western Rat Snake – Often seen swimming or climbing trees.
- Speckled King Snake – A non-venomous snake known for its black and yellow speckled pattern.
- DeKay’s Brown Snake – Prefers moist environments and is frequently found near the shoreline.
The western rat snake, in particular, is highly skilled in the water, making it one of the most frequently encountered species in this lake. These snakes can grow between 3 feet 6 inches to 6 feet (106.5 cm – 183 cm) in length. Although harmless, their presence can be unsettling for some visitors.
The eastern copperhead, a venomous snake, has also been spotted at Lake of the Ozarks. While not overly aggressive, this snake can deliver a painful bite if provoked. To stay safe, avoid walking through dense vegetation and keep an eye out while near the water.
How to Stay Safe Around Snakes in Missouri’s Lakes
While snakes are a natural part of Missouri’s ecosystem, taking precautions can help ensure a safe and enjoyable outdoor experience. Here are some essential safety tips:
- Stay on Designated Trails – Avoid venturing into dense vegetation where snakes may be hiding.
- Watch Where You Step – Always check the ground, especially near rocks and logs.
- Wear Protective Clothing – Boots and long pants can help prevent snake bites.
- Keep a Safe Distance – If you see a snake, back away slowly and avoid sudden movements.

Conclusion
Missouri’s lakes offer some of the most stunning outdoor experiences, but they also come with the presence of various snake species. Whether you’re swimming, boating, or camping, being aware of your surroundings is crucial.
From Smithville Lake’s DeKay’s brown snake to Table Rock Lake’s common watersnake and Lake of the Ozarks’ western rat snake, each lake has its own unique ecosystem. While most of these snakes are non-venomous, venomous species like the eastern copperhead and pygmy rattlesnake do exist in certain areas.
By staying alert and respecting wildlife, you can enjoy Missouri’s lakes safely while appreciating their natural beauty.
