Two men were fishing on the Occoquan River in northern Virginia when the motor on their boat failed. The boat began drifting toward the downstream Occoquan River Dam, which has a 72-foot drop, so the men abandoned it before it was swept over, grabbing onto a pole affixed to the top of the dam. The Prince William County Fire Department asked the Park Police for assistance with a hoist rescue, and Eagle 1 responded with a crew of four â pilot Kevin Chittick, co-pilot Ken Burchell, and rescue technicians Mark Varanelli and David Hurley. One fisherman was pulled to the shore by a Fairfax Police Department helicopter; the second fisherman was only a few feet from being swept over the dam when the USPP officers hoisted him onboard Eagle 1. According to rescuers familiar with the dam, a plunge down the dam face would have been âdefinitely fatal.â
