I did look in the water several times and all I saw was sulphurs of varying color(orangish yellow, pale yellow, creamish, and even almost white) in size(16-20). I did see a few sparse cahills and small olives, but it seemed like a full blown sulphur hatch to me. I should have taken a closer look, I'm sure there was something going on that I wasn't seeing. As far as flies go, heres a short list. Sulphur Patterns used: pale yellow cdc and deer hair comparaduns(16-20), polywing thorax patterns (16-20), half and half emergers (16-20), pale yellow and orangish parachute (16), breakout emerger (16-20), cream spinner (18). Other patterns used: iso parachute (12), iso emerger (12), March brown emerger (12), March brown breakout(12), parachute olive (20). I threw some other stuff too, but that gives you an idea. Unless they were feeding on a different bug I wasnt seeing, I feel those patterns should have worked at least good enough. I think the biggest problem I had was how I had to position myself to present the fly. I had very little backcast room(had to wade out above my waist to have any), and I also had to position myself slightly downstream and across from the fish that were rising in a slower back eddy, which made it harder for me to achieve a long, drag free drift. These are all things that can usually be overcome, but it was far from an ideal casting/presentation scenario.
Dryflyguy, guestward ho is about 12 miles or so southwest(I think) of deposit. It's not an ideal location, but the campground is overall pretty decent with a fireplace, running water and an electric outlet at the campsite, and a bathroom and suitable bathhouse close to the primitive campsites. It was like 10 per night which is pretty cheap. My only real grievance is that they hit you over the head with a bat when it comes to buying firewood, 12 dollars for 2 handfulls of wood, which was wet and didn't burn well when we got it. It was about 10-15 mins from hale eddy, and about 15 mins from deposit.
