Understanding the Presence of Snakes in Wisconsin’s Lakes and Rivers
While many people view lakes and rivers as peaceful, tranquil places, they can also be home to a variety of wildlife. Among these creatures are snakes, which may not always be the first thing that comes to mind when thinking about freshwater environments. However, in states like Wisconsin, certain lakes and rivers are known for their snake populations, making it essential for visitors to be aware of what they might encounter.
Popular Waterways with Notable Snake Populations
Several rivers and lakes in Wisconsin are known for having significant numbers of snakes. The Mississippi River is one of the most notable, running through the state and attracting swimmers, fishermen, and boaters. Along this river, visitors might spot various species such as the common garter snake, common water snake, timber rattlesnake, DeKay’s brown snake, ring-necked snake, and eastern milk snake. While most of these snakes are non-venomous, two species stand out: the timber rattlesnake, which is highly venomous, and the ring-necked snake, which is only mildly venomous and generally harmless to humans.
Another key waterway is the Fox River, which flows through Lake Winnebago and extends toward Green Bay. Here, the eastern fox snake is one of the more commonly seen species. These snakes, although they may appear intimidating due to their coloration, are not venomous. Other snakes found along the Fox River include the northern water snake and the common garter snake, both of which are considered safe for humans.
Lakes Known for Their Snake Activity
Devil’s Lake, located within Devil’s Lake State Park, is another area where snake encounters are possible. Despite its name, the lake offers beautiful scenery and recreational opportunities. The most commonly seen snake in the area is the northern water snake, which is not considered dangerous. However, there have been rare reports of timber rattlesnakes in the region, which should be taken seriously due to their venomous nature.
Lake Winnebago, the largest lake entirely within Wisconsin, is also home to several snake species. The common garter snake and eastern garter snake are the most frequently encountered, and while they are mildly venomous, they do not pose a serious threat to humans. Similarly, Castle Rock Lake, a man-made body of water near Wisconsin Dells, is home to common garter snakes and occasionally common water snakes. Both of these species are non-threatening to humans.
Lake Michigan, one of the Great Lakes, also has its share of snakes. Visitors may come across garter snakes along the shore or in nearby wetlands, and water snakes can be found in shallow waters. While these snakes are not considered dangerous, they can still startle those who are not expecting them.
Tips for Safe Encounters
Even though most of the snakes found in Wisconsin’s lakes and rivers are not aggressive, it’s important to remain cautious. If you do come across a venomous snake, such as the timber rattlesnake, it’s crucial to seek medical attention immediately. Avoid using a tourniquet, ice compress, or trying to suck out the venom, as these methods can worsen the situation. Instead, keep the affected area below heart level and get professional help as soon as possible.
For those who enjoy exploring natural areas, being aware of local wildlife can enhance the experience. Whether you’re a snake enthusiast or simply looking to enjoy the outdoors, knowing what to expect can make your time in Wisconsin’s lakes and rivers more enjoyable and safer.
