Lake Michigan — it’s a beautiful lake, but it can be deadly.

As of June 19, there had been 28 drownings in the Great Lakes so far this year.

Ten of them occurred in Lake Michigan.

Dave Benjamin, the co-founder and co-executive director of the Greater Lakes Surf Rescue project, said the “basic dynamics” of the lake make it the deadliest of the Great Lakes in terms of drownings.

“There’s a high population density along the shoreline,” Benjamin said, “and it’s a tourist destination. … It’s 300 miles long from the north to the south, and from east to west, it’s 118 miles wide, and wind over water creates dangerous currents. So it’s the winds that are creating the dangerous currents.”

The current statistics could be even higher because of underreported, misreported and nonreported drownings, Benjamin said.

The dangerous currents in the Great Lakes are caused by the winds and are often difficult to spot. The rip current channels open and close creating what is called a flash rip.
