Reasons To Take Caution

Lake Michigan is the second-largest Great Lake, but it is also the deadliest lake. The lake received this title due to the number of drowning each year, with an average of 38. [source]
Some of the below reasons deal directly with contamination or pollution, so the Indiana Department of Environmental Management (IDEM) has implemented the Lake Michigan Beach Monitoring and Notification Program. This program partners with beach managers and staff that collect and test water samples
Rip Currents
Due to the shape of Lake Michigan (eggplant) and the north to south orientation, there are deadly currents that could form. Authorities at times close off beaches and post warnings alerting swimmers not to enter the hazardous waters.
The rip currents develop from high winds coming across the lake’s surface. The winds are extremely fast as there are no obstacles in the water to slow them down.
Large amounts of water forced towards the shore escape by a rip current which forms a stream of water in the opposite direction. Swimmers getting caught in a rip current might be taken away from the shore. The rip currents are enough to proclaim the title from the San Francisco Bay and the Mississippi river of being the place where people have to think twice before swimming.
Presence Of Bacteria
Most of the beaches that border Lake Michigan monitor the levels of E. coli several times a week. Depending on their findings, the beaches are closed off, or posted signs warn beachgoers about the potential dangers.
E. coli can result in diarrhea, vomiting, and infection. Authorities also use this information as evidence of feces in the water. This presence means that other harmful bacteria or even pathogens are present.
Fecal matter is the host for E. coli and can enter the water via runoff or overflow from farms, waste management plants, or even pets on the beaches. But scientists have discovered that the main culprit is seagulls and other water birds.
Reduced Water Quality
Besides being a preferred recreational location, Lake Michigan is the source of drinking water for millions of individuals, including the origin of tap water for the residents of Chicago.
Unfortunately, toxic chemicals can pollute the waters and affect both uses. State authorities and the Environmental Protection Agency monitor the lake to ensure the water stays safe. However, there are reports of chemicals leaking into the lake.
Citations were issued to US Steel several times for dumping or leaking chromium in Lake Michigan. Residents on the southern section of the lake reported chemical smells and, on occasions, left the lake with infections and rashes.
Developing Hypothermia
The wind and the waves typically prevent the lake from freezing during the winter season. Although the water in Lake Michigan remains cold all year round, temperatures below 70 degrees Fahrenheit can result in hypothermia.
Swimmers might suck water into their lungs when they gasp after the surprising effect of the cold water. The body temperature decreases 25 times faster, possibly taking the swimmer’s strength. Once the body temperature of a human falls below 95 degrees Fahrenheit, hypothermia can develop.
Exposure To Parasites
Globally, Giardia and Cryptosporidium are parasites that result in waterborne illnesses. The parasites enter the water once it comes into contact with the feces of infected individuals or animals.
Waste management facility overflows, runoff from agriculture, or improperly functioning sewage systems can introduce these parasites into the lake.
What Is At The Bottom Of Lake Michigan?
The deepest section of Lake Michigan measures approximately 925 feet. Below these waters, scientists discovered a prehistoric carving of a mastodon, an ancestor of the modern-day elephant, plus a series of stones oriented in the shape of a ring, closely resembling the Stonehenge. [source]
There is also an eleven-foot statue holding a life-sized crucified Jesus Christ. The white marble statue lies beneath the waters of Lake Michigan as a memorial to those who have passed away while diving.
