The Animas river is a technical river. Its tough even for seasoned fisherman to catch fish every trip. I have had my share of bad days on the river, and been skunked many times. However I caught lots of fish this trip, but they were all very small. They were pretty little fish, just really small.
I was using a grasshopper pattern in the morning dropping to a nymph for most of the morning. Then switched to a slump buster streamer in the later afternoon. All of which were covered in moss at almost all casts. Just lots and lots of moss, all day long.
