I didn't end up fishing Coffee Creek as I had originally planned, rather sticking to the Upper Trinity River as our campground was right on it. It was a lot of fun, really nice small pocket water type of stream, although they said it was a low water year. The water was pretty warm as well and made me wonder how the rainbows managed to live through the scorching summer heat in that stream. If I was going to go back, I think I would target late May or early June. The river ranged from 20-45 feet wide and had a pretty good variety of water on it. There was a really long, wide riffle that went past most of the campground, but the deepest spot was probably 9-10 inches. I didn't fish that area at all. At the bottom end of that, the river narrowed and the gradient increased producing a very nice 150 yard series of drop pool pocket water with depths up to 3 feet. Past that was a nice run against a cut bank where the river turned, followed by a 1.5 foot deep stretch of riffle water which dumped into a long slow pool of 10 feet deep. I fished the entire length of that over 2 days, maybe 7-8 total hours of fishing. i didn't fish hard as I wanted to hang out with the GF and our puppy too, but did have some success. Despite trying at all times of day, I never did raise a fish to a dry fly. I saw no adult aquatic insects in 2 days and despite turning over a bunch of rocks only managed to see a few large cased caddis and nothing else. I fished hoppers and flying ant patterns on top. I tried streamers at first and last light in the deep areas to no success although I did get one 8" fish on a size 14 sparkle bugger against the cut bank. High stick nymphing the drop pool water was most successful. I fished a prince nymph followed by a soft hackle most of the time. A size 14 amber and partridge soft hackle was the most productive fly. I caught 17 fish in the 2 days, ranging from 4"-14" with the average somewhere around 8". All great fun on my 3 weight CT. I did hook one fish that I wish I could have landed. It happened to be my third cast of the trip, nymphing a 2.5 foot deep pool directly behind a smart car sized boulder. I hooked it and it took of downstream, going airborne near the end of that pool. Then it turned and headed back upstream and leapt over that front boulder and landed in the next pool upstream, where it tossed my hook. It was incredible, I guess the was in the 16-17" range and shocked the hell out of me. I had to sit there for the next 5 minutes trying to figure out what just happened! All fish were native rainbows and very pretty. I didn't take any pictures as the water was warm and didn't want to stress them anymore than I already had. The rocks in the area are lighter in color than here in Washington and as such, these fish were almost platinum in color without a ton of spots and green-gray on their backs. Much lighter in color than rainbows I'm familiar with. I did hear report of a 21.5" fish getting hauled out of that deep pool the first weekend in June, but I don't know if I buy it. There are large fish in that system though. I didn't see another angler on the roughly half mile of stream I fished in 2 days and the campground only had 1 other site occupied on the Fourth of July so I don't think it gets much pressure. I would like to spend a week there in June camping and fishing, I hear that the alpine lake in the area fish really well too, 7 days of camping and fishing split between alpine lakes and gorgeous productive small streams, what's not to love!
