Abstract: At approximately 9:00 a.m. on May 21, 2024, six individuals, including Employee #1 (deceased), were performing underwater work to clean out lake weeds 10-15 feet below the surface of Lake Lavon in Apple Valley, MN. After several minutes, coworkers noticed they had not seen bubbles from the deceased and found him unresponsive 15-20 feet underwater. The employee was wearing a wetsuit, scuba mask, and weight belt, but the regulator was out of his mouth at the time of discovery. This was the employee's first time diving underwater and using scuba equipment, and he had received 10-15 minutes of training prior to the dive from a coworker who was not scuba certified. The employee was pronounced dead at the scene.
