America is known to have a lot of lakes. Many of the 240 freshwater lakes in the United States were formed by glacial processes during the last Ice Age. These lakes are filled with marine life and many wildlife, such as gray wolves, moose, and Canadian lynxes.

It’s no shocker that Americans love water sports and activities. Since there are so many water activities loved by Americans, a lot of these lakes get visited frequently. While a lot of them are great spots for swimming, fishing, kayaking, boating, and waterboarding, there are several lakes that are marked as danger zones.

Here are 5 of the deadliest lakes in the country.

1. Lake Michigan

Lake Michigan is one of the five Great Lakes and is located near the border between the USA and Canada. It has an area of 22,406 miles² and a length of 307 miles. Due to its size, the lake is quite a popular spot for sailing, fishing, and boating.

Despite its strong attraction, there’s a bleaker side to Lake Michigan. It has very strong undercurrents that lead to many deaths each year. Many swimmers have lost their lives at the sudden change in the waters. Lake Michigan is no stranger to boating accidents, either. In the fall, Lake Michigan is even more dangerous as changes in water and temperatures occur. The lake is considered to be the deadliest in the United States.

To many, it is shocking that the lake is still visited year-round, despite its dangers. However, since there are no laws against it, swimmers and boaters still visit. Many find it hard to resist the lake’s beauty as well as the many species of fish that live in it.

Lake Michigan is known to have trout, salmon, and bass, making it perfect for fishing trips. In 2020, 53 people drowned in Lake Michigan, setting a record for yearly drowning deaths.

2. Lake of the Ozarks, Missouri

Although many people refer to Lake Michigan as the deadliest, a lot of people would argue that the Lake of the Ozarks, Missouri, deserves the title- and it’s quite easy to see why. According to the Missouri Highway State Patrol, there were 14 fatal drowning incidents in the lake. Although swimming is not allowed in many parts of this lake, it hasn’t stopped people from trying, and many have died.

The lake also has a high record of boating accidents and even attacks by some of the deadly animals. Even the waters in this lake are deadly. The Lake of the Ozarks has been found to have high levels of E.coli. It is also home to a large array of venomous snakes, which include massasauga, copperhead, pygmy rattlesnake, timber rattlesnake, and cottonmouth. These snakes are venomous and are known to fatally attack humans. What’s more? Alligators have also been sighted in these lakes.

This isn’t to say that the lake is totally off-limits. The Lake of Ozarks has various safe beach areas. They have been opened to the public for fishing and other activities. However, visitors to these parks must obey all the rules that they are given. Some other animals you can find in the Lake of the Ozarks are bobcats, bald eagles, coyotes, elks, eastern chipmunks, and even black bears.

3. Lake Mead

Known as one of the best lakes for scuba diving, Lake Mead is on the main stem of the Colorado River.

Scuba divers all around America have heard of lake Mead. The lake, which is ranked as one of the top freshwater lakes, is perfect for scuba diving. Its waters are inhabited by striped bass, channel catfish, and even bluegills. Lake Mead is also known as the reservoir of Hoover Dam. It is one of the largest man-made bodies of water.
Sadly, it is also one of the deadliest lakes in the USA. According to Wilk Jeffery’s “Wilks Journal of Travel Medicine”, the highest number of international visitor fatalities was recorded at Lake Mead. From 2006 to 2016, 275 people were recorded to have died on the lake. Some of the most common causes of deaths on the lake are drowning and car crashes. Lake Mead is also home to several dangerous reptiles and amphibians.

4. Mono Lake

Mono Lake is beautiful. In the right weather, the skies are a brilliant blue and there is a light breeze in the air. At sunset, the sky and lake are stunningly colored with various types of birds such as parasitic jaegers, black terns, and Sabine’s gulls. Unlike some of the other lakes on this list, Mono Lake isn’t plagued by boating or drowning incidents nor is it filled with dangerous predators. Mono Lake is dangerous because of the lack of water.

The Lake is an old saline lake. Located in California, it is set towards the east and at the edge of Sierra Nevada. However, the lake isn’t connected to any other body of water. So, when chemicals get into the lake, they do not flow out but stay there and pollute the water. Sadly, the lake has built up an alarming concentration of arsenic. The water is now poisonous and toxic to humans and animals.

In addition, the lake is slowly shrinking. According to the Mono Lake Organization, the lake dropped by 45 feet in 40 years. Due to its state, Mono Lake has no fish. However, it is filled to its bream with alkali flies and brine shrimp. These marine creatures are prey for the various types of birds the lake has.

The Mono Lake Organization was established to save the lake. The organization states that although water is beginning to flow back down the streams and into Mono Lake, there is still much to be done as the lake is still in a dire situation.

5. Lake Erie

Lake Erie spans an area of 9,940 mi² and is the fourth largest of the five Great Lakes.


Lake Erie is not enjoyed by swimmers for much of the year. Agricultural and urban runoff of nutrients such as nitrogen and phosphorus has spurred annual algal blooming since the 1960s.

Sadly, algae are not the only problems the lake faces. Lake Erie is also known for its sudden drowning currents. In 2021, six drowning incidents were reported in the lake. According to the Great Lakes Surf Rescue Project, several other fatal incidents have been reported on the lake. Since swimming is not prohibited in these lakes, it is common to find daring swimmers in these waters. However, medical experts have advised children, pregnant women, and those with certain underlying conditions to stay out of the lake.

Some of the marine life found in Lake Erie include Northern pike, steelheads, walleyes, and smallmouth bass.
