The department’s fire chief described the operation and how difficult it was to complete it.

“This was a very complex water rescue given the location of the boat on the lake and that it was nighttime. We had to maneuver the rescue boat through shallow water to reach the victims and then free their boat so we could tow it in,” Fire Chief Joseph Lindaman said. “I want to complement our Police Dispatcher who did an excellent job of helping pinpoint the location of the boat. She also stayed on the line with the caller until rescue personnel arrived on scene assuring the victims help was on the way, while dispatching all of the responding units.”
