The Most Snake Infested Lakes in Michigan

Michigan is home to 18 species of snakes across its vast wildlands. Notably, only one of these species is venomous, the Eastern massasauga rattlesnake, making snake-related fatalities very rare in this state. While most of Michigan's snakes also live primarily on land, we will focus on the lakes (of which there are many in the region of the United States) with notable populations of aquatic or semi-aquatic species. Read on to learn about where specifically to look for these reptiles, their natural behaviors, and how to best ensure both your and their safety to help maintain healthy local ecosystems.

Lake St. Clair

Lake St. Clair sits on the border between Michigan and Ontario and is one of the state's largest bodies of water, but also one of its shallowest, with an average depth of only around 12 feet. The relatively warm, shallow waters and abundant vegetation of Lake St. Clair notably support a thriving ecosystem, attracting snakes in significant numbers, especially during the warmer months.

Its extensive shoreline and wetlands create a perfect habitat for various species of snakes, including the northern water snake and the eastern garter snake, two snakes that are commonly found all across Michigan and will come up several times on this list. These non-venomous species are common sights on the lake’s shorelines, marshes, and reed beds, where they hunt for prey such as small amphibians and fish. The dense vegetation and marshy areas around the lake provide cover for them, making encounters more likely for those exploring the shoreline by boat or foot.

On a more mythical note, Lake St. Claire is also said to be inhabited by a giant serpent of some kind, a creature that has been described as a fast moving snake or eel. The cryptid allegedly dragged a horse into the water, although this was reported in 1897. Thankfully, few sightings have been recorded since!

Lake Orion

Lake Orion, located in Oakland County, Michigan, is known for its clear waters and scenic views, but it also hosts a notable snake population. The lake's surrounding wetlands and shoreline provide a suitable habitat for various species of snakes, particularly water snakes like the northern water snake.

These harmless snakes are often seen in the shallow parts of the lake, where they prey on fish and amphibians. Although non-venomous, the northern water snake's size and aggressive response when threatened can be intimidating for those unfamiliar with it.

Though generally not dangerous to humans, it’s wise to maintain a respectful distance from the snakes and be aware of their presence while enjoying activities such as boating or fishing. Orion Lake remains one of the lakes in Michigan where snake sightings are relatively frequent, particularly during the warmer months of the year when the snakes are active.

Long Lake

Long Lake, located in the northern part of Michigan's Lower Peninsula near Traverse City. Beside being a popular spot to spend some time in the summer, it is known among locals for its significant population of snakes.

The lake’s wetlands and surrounding areas are mainly home to water snakes, such as the northern water snake, which is often seen basking on rocks or swimming near the shoreline. Long Lake's warm, shallow waters create an ideal environment for this species to thrive, as the lake provides plenty of prey, including small fish and amphibians. The lake's natural features also include dense aquatic vegetation and calm waters, making it a thriving habitat for these reptiles. Although northern water snakes are generally harmless, you should still stay cautious and respectful of their habitats for both your safety and theirs.

Houghton Lake

Houghton Lake, one of the biggest natural lakes in the United States and Michigan's largest inland lake, is home to more than just fish and summer vacationers. The lake's surrounding wetlands, marshes, and grassy shallows, make it an idyllic environment for a variety of snakes as well.

At Houghton Lake, species such as the queen snake, northern water snake, and eastern garter snake are commonly observed. None of these snakes are venomous or pose a threat to humans, though their presence in the lake's vegetated zones can occasionally startle boaters or anglers. Visitors and cottagers should stay aware of the snake population when exploring the shoreline or enjoying water activities, always keeping a safe distance from these reptiles.

Lake Fenton

Lake Fenton sits in southeastern Michigan, a short drive north of Detroit, and is quite shallow, with surrounding wetlands to match. Typical Michigan species of snakes that like to live in the water, like the Northern Water Snake, are abundant here. These non-venomous snakes mainly survive by eating fish, frogs, and other small aquatic creatures like crayfish in Lake Fenton.

During summer, snake activity increases, making sightings near the shoreline or in the water common. Fenton Lake is also abundant with fish and popular among anglers in Michigan. Fish there for small and largemouth bass, northern pike, bluegills, pan fish, and more.
