Because the water in the stream I fished was low this fall and we got a foot of snow Sunday, it was iced up worse than I'd ever seen. While normally just the edges freeze, there were massive, thick ice sheets on the banks I had to chop through to reach the open water. There was, in my opinion, enough open water in normally productive spots that I figured I'd still catch a few fish. In fact, I was thinking at mid-day they might even gravitate to the open water because it would be a tad warmer in the sun. Keep in mind it was not just the fast water that was open. There were some slower pools that hadn't completely iced over.
