Had an icy afternoon yesterday on the Clark Fork. I fished an access about 20 miles upstream of Missoula, hoping that there would not be as much ice compared to the lower river. Turns out there was just as much ice. I had a pretty tough time getting a vertical drift with my nymphs.
I fished for a while and couldn't manage to hook up with any fish. I spent the next half hour sitting on the bank. It was a nice day on the stream, even though I could barely fish.
