A Grand Junction man drowned in Blue Mesa Reservoir on Tuesday, July 4th. Glen Shook, 77, had stayed overnight in his cabin cruiser on the West Elk arm of the reservoir. Around 6:30 a.m. on Tuesday, Shook was attempting to retrieve driftwood from the water when he fell overboard. A passenger on the boat failed in an attempt to throw a floatable cushion to him, then called for help on the boatâs marine band radio. The park was notified and rangers responded within the hour. Shookâs body was recovered by a park diver in about six feet of water.
