Iowa, a state celebrated for its picturesque landscapes and tranquil lakes, has an unexpected visitor lurking in the waters and along the shorelines—snakes. While these reptiles play an important role in the ecosystem, certain lakes in Iowa are notorious for being snake hotspots.

Whether you’re an avid swimmer, fisherman, or nature enthusiast, it’s crucial to know where the snake population is particularly dense to avoid dangerous encounters. Below are 11 Iowa lakes known for their snake infestations. If you’re planning a visit, proceed with caution or consider an alternative destination.

1. Lake Okoboji (Dickinson County)

Located in the heart of Iowa’s Great Lakes region, Lake Okoboji is one of the state’s most popular tourist destinations. However, this stunning lake is also home to a variety of snake species, including northern water snakes and eastern garter snakes. While these species are generally non-venomous, their numbers are high around the lake’s shoreline and marshy areas. Swimmers and boaters should be cautious around the lake’s shallows, where snakes tend to lurk.

2. Big Creek Lake (Polk County)

Big Creek Lake is a beautiful spot for fishing and boating, but it’s also home to a dense population of snakes, including the water moccasin and northern water snake. These reptiles thrive in the lake’s shallow, weed-filled areas, where they hunt for food and seek shelter. If you’re planning to visit Big Creek, be especially cautious in the water’s edge and along the marshy shorelines.

3. Clear Lake (Cerro Gordo County)

As one of Iowa’s most beloved lakes, Clear Lake attracts many visitors each year. However, it’s also home to a variety of snakes, including the common water snake and eastern garter snake.

A vast and scenic lake, Lake Red Rock offers countless opportunities for outdoor recreation, including hiking, camping, and water activities. However, it’s also known for having a high population of snakes. The shallow waters and densely vegetated areas around the lake provide the perfect habitat for water snakes, such as the northern water snake. While most of these snakes are non-venomous, their sudden appearance in the water or along the shoreline can be unsettling for many visitors.

5. Saylorville Lake (Polk County)

Another lake located near Des Moines, Saylorville Lake is popular for fishing, boating, and camping. Unfortunately, this lake is also notorious for its large population of northern water snakes. These snakes are often found along the water’s edge, particularly in the shallow, weedy areas. Though generally harmless, the large number of snakes can create an uncomfortable experience for anyone swimming or paddling close to the shore.

6. Lake Macbride (Johnson County)

Located in Lake Macbride State Park, this beautiful lake offers a peaceful retreat for outdoor lovers. However, it’s also home to a variety of snake species, including the northern water snake and the eastern garter snake. The lake’s marshy shorelines and submerged rocks provide ideal hiding spots for these snakes. If you’re visiting the area, be cautious when venturing near the shoreline, as the dense vegetation may conceal them.

7. Black Hawk Lake (Sac County)

Black Hawk Lake is another popular recreational spot for boating and fishing, but it is home to numerous snake species, including the water moccasin and common water snake. These snakes are most commonly found in the lake’s shallow, slow-moving waters, where they thrive. If you’re walking along the shoreline or fishing from the bank, stay alert—especially near areas with dense vegetation, where snakes tend to hide.

8. Lake Anita (Cass County)

While Lake Anita may seem like a peaceful, family-friendly spot, it also plays host to several species of snakes, including the northern water snake and garter snake. The shoreline is often lined with tall grasses and cattails, making it an ideal location for snakes to hide. If you’re planning to swim or fish here, it’s best to stay away from the water’s edge, especially in the early morning or late afternoon when snakes are more active.

9. Hickory Hills Lake (Linn County)

Hickory Hills Lake, nestled within Hickory Hills Park, is a serene and scenic spot for fishing and canoeing. However, this tranquil lake is also home to various snake species, including the harmless but numerous northern water snake. These snakes are often found in the shallow, weedy areas near the shoreline. While they generally avoid humans, their presence can be unsettling for those who are not expecting to see them.

10. Rathbun Lake (Appanoose County)

Rathbun Lake, one of the largest man-made lakes in Iowa, is a popular spot for fishing, boating, and camping. However, it is also known for its large snake population. Northern water snakes are commonly found near the lake’s shoreline, especially in areas with dense vegetation and shallow water. These snakes are not typically dangerous but can be aggressive when threatened. Visitors should exercise caution around the lake, particularly when swimming or fishing.

11. Lake Wapello (Davis County)

Located in Lake Wapello State Park, this scenic lake is surrounded by lush vegetation and marshlands, creating an ideal environment for snakes. Water moccasins and northern water snakes are commonly spotted along the shoreline, often resting on rocks or swimming through the water. Visitors to this lake should stay alert and be cautious when hiking or walking near the water, as snakes are known to blend into the environment and may not be immediately visible.

While Iowa’s lakes offer plenty of opportunities for outdoor recreation, they are also home to numerous snake species that can pose a danger to unsuspecting visitors. From non-venomous water snakes to more dangerous species like the water moccasin, these lakes are prime habitats for reptiles.

If you’re planning a trip to any of these popular lakes, it’s important to stay vigilant, particularly when near the water’s edge or in areas with dense vegetation. Always watch where you step, keep a safe distance from the shoreline, and educate yourself about the local wildlife to ensure a safe and enjoyable experience.
