As it turns out it was even more difficult than I expected. There were only a couple of trails and the undergrowth was thick and composed almost entirely out of thorn bushes. But I eventually crawled, climbed, jumped, and bled my way to the stream. It was a perfect, classic brook trout stream. From my first couple of looks I expected it to be loaded with 3 to 5 inch brook trout. The first thing I do when I fish a new stream is quickly walk a long stretch to spook fish. When I did that this evening I spooked hundreds of brook trout, but they were not 3 to 5 inchers... they were 6 to 12 inchers! There was at least one big fish in every pool and glide, and often two or three. When I spotted a perfect undercut bend pool I decided it would be the first place I would catch a fish. It was. I put the Ausable Ugly past the big boulder and It got eaten. I set the hook and briefly battled the fish. What I landed was an incredibly stunning specimen, a chunky male with kype, blue in the mouth, hump on the back, and spots that could make other brookies jealous.
As I continued downstream I saw more big brook trout. Then I came to a classic spot. The current hit a big rock, forming a deep pocket in front of it with a ripple on the surface, and a glide going around the rock. I made my cast into the glide, than twitched the Ugly into the pocket. The second cast got eaten. The third I hooked up, and a huge brook trout splashed at the surface. A few more missed takes and it gave up on the Ugly. I changed to a fly I had with me that is just not in my brook trout stream arsenal: a size 6 2x long olive Woolly Bugger. The big fish slammed it on the first cast. I missed again and this time it didn't come back at all. But I do know where it lives know, and better yet I know a stream with brookies big enough and aggressive enough to go after a sizable streamer.
