Hahaha. Both are good thoughts.
OK just to clarify, Spring fed streams with no snow melt temperature in the low to mid 20sF
Interesting. Are the springs underground… thus geo thermal? Just weird the banks seem melted and no signs of ice. What were the water temps? Considering those air temps, I would expect that the ice would start closing up that river considering the flow.
I have fished those temps but usually by accident or during days that will eventually crest freezing. I find below freezing a challeng and success more of a mystery on how and when fish will be active.
