Although there are 46 different species of snakes in the state, rattlesnakes are the only venomous ones found. The majority of California snakes can be found in its desert areas, but many of them can be found in shallow water bodies such as lakes. According to World Atlas, there are about 3,000 named lakes and reservoirs in the state, of which one might wonder which are safe for a swim and which are not. This article contains some of the most snake-infested lakes in California.
Aquatic Snakes Found in Californian Lakes
California pales in comparison to Texas, the state with the largest number of snake species in America. However, the Golden State has more than its fair share of snakes, with about seven being venomous. California’s seven venomous snakes are rattlesnake species, which spend most of their lives outside water. None of the water snake species found in the United States is native to California. The water snakes found in California are invasive water snake species believed to have invaded the state from Florida. This, however, doesn’t mean that California’s lakes are void of snakes. The state is known to have aquatic garter snake species that are sometimes seen swimming expertly in Cali’s water bodies. Some other garter snakes found in Californian lakes are the Sierra, western terrestrial, and the checkered garter snake. Despite this, California’s lakes are free of venomous snakes as there is only one venomous aquatic snake species in the United States. That snake is the cottonmouth, which luckily, is not found in California.
6 Most Snake-Infested Lakes in California
Most sightings of aquatic snakes in California have been in Roseville and Sacramento. Here are six of the most snake-infested lakes in California:
1. Machado Lake, Harbor City
Machado Lake is located in Harbor City. According to reports, the lake has been associated with heavy pollution, bacteria, alligators, and black snakes in recent years. The 45-acre lake has been victim to illegal dumping, thus impairing the water quality of the lake. However, this has not reduced the presence of snakes in and around the lake. According to news reports, southern water snakes can be found in Machado Lake. The increased population of water snakes in the area was believed to be because of pet owners letting their pets go.
2. Lafayette Reservoir
Lafayette Reservoir is a storage reservoir for East Bay Municipal Utility District. The 1.4 billion-US-gallon lake is commonly used for boating and fishing. The reservoir is surrounded by hills and forests, drawing people who love dirt hiking. The landscapes around the large reservoir have several snake species. According to the Lafayette Reservoir Check List, some common snakes found in and around the reservoir are the gopher snake and the California kingsnake.
3. Bear Gulch Reservoir
Bear Gulch Reservoir is located in Woodside, California. According to Menlo Park, this lake, containing over 100 million gallons of water, provides water to over 50,000 people in the Bear Gulch District. The National Park Service states that the area has 14 diverse snake species. Some common snakes in the area are the common garter snake, the gopher snake, and the western rattlesnake. The area was named after a bear attack incident in 1850. Bear Gulch Reservoir is closed to the public, and swimming is prohibited. This was done to preserve the declining population of animal species in the lake, such as the endangered California red-legged frog.
4. Folsom Lake
Folsom Lake is a reservoir formed by Folsom Dam. It is located on the American River, touching Placer, Sacramento, and El Dorado Counties. People head to the lake and its recreational park, especially in summer, to cool off. The lake is also popular for its rainbow trout and bass. However, aquatic and semi-aquatic snakes can swim along the lake on warm afternoons at certain times of the year. According to reports, one factor that affects the population of aquatic snakes in Folsom Lake is the accumulation of debris in the lake. The debris reduces the lake’s depth and makes good hiding places for these aquatic snakes. They are only a few snakes that burrow their own holes, but none of them is a water snake. Instead, these snakes use holes dug by other animals.
5. Lake Natoma
Lake Natoma is a small lake between the Folsom and Nimbus Dams in Sacramento County, CA. Like Folsom Lake, the smaller lake occurs along the American River and has a length of 4 miles. Surrounding the lake are cliffs, plateaus, foothills, and canyons. The lake offers a fantastic location for recreational activities such as kayaking, fishing, and skiing, and is a good habitat for snakes. According to the California Department of Fish and Wildlife, aquatic snakes such as the southern water snake are found in and around Lake Natoma. These snakes reproduce fast and have various diets, including fish and amphibians.
6. Lake Tahoe
Lake Tahoe is the second largest and deepest lake in California, spanning a surface area of 191.58 square miles with an average depth of about 1,000 feet. This freshwater lake is famous for its crystal clear water with no sharks or alligators. However, Lake Tahoe is not completely safe, as it ranks as one of the most snake-infested lakes in the United States. Lake Tahoe has a large area of its banks surrounded by coniferous forests, which are suitable habitats for snakes. According to news reports, Lake Tahoe Basin has had a rise in the presence of rattlesnakes and other snake species in recent years due to climate change. While they are majorly land snakes, these rattlesnakes can swim in search of food, mates, or new habitats. Other snakes that have been sighted include the common water snake.
