Rock did not produce anything for us, but remember we were in kayaks and not paddling more than a few miles or so from the launch. Amber was just great before we got there, ain't that the way it is. We decided to leave Rock about 10ish and drove to Amber. We tried every type of fly in our boxes even some real ugly ones that I tied for fun with hippy beads. Tried floating line, sinking line, trolling, drifting, sitting still and working one area, nothing.
One guy had some luck on a San Juan worm early in the AM! I looked in all my fly boxes as I know I had some as we used them a lot in Alaska as soon as the ice left the lakes, couldn't find one damn San Juan worm until I got home and found some other boxes I left home.
Talked with an elderly fella that said the fish were hitting like crazy before 10 and then it just ended.
Anyway had a great day lots of sun, lots of water fowl, fresh air and fun being out with my wife.
