A rescue operation was conducted in Lake Michigan near a Chicago beach. A boat had sunk in the lake, and Coast Guard crews were called to the scene. The cause of the sinking was attributed to heavy fog and rain, which overwhelmed the boat's pumps.

The Coast Guard crew used flotation devices to raise the sunken boat. These devices were attached to the boat and then inflated, allowing the vessel to be lifted above the water.

Further details about the incident are available from the source, including the events leading up to the rescue operation.
