Fished Gray Reef last year over Memorial Day Weekend. We rented a drift boat. Also one of the guys floated in his pontoon boat. If I remember correctly water was running about 3,000-4,000 CFS. Today it is running at 5400. Boat control is everything. We were rookies, and had few hookups, because of lousy boat control. I had the best luck right below the dam wading. Some good fish there. Caught fish on small zebra midges under a strike indicator.
