During the dinner hour, tones dropped for Rescue 21 to assist crews operating on a swift water rescue in the Schuylkill River at the Flat Rock Dam. Gladwyne Fire Company was in service with their swift water rescue team to rescue two jet skiers who went over the dam and were stranded on the rocks below. Members stood by down river with throw bags and assisted with rigging lines for rescuer safety. The company was in service for two hours. Excellent job to all responders navigating sometimes treacherous waters.
