Colorado Stream Update: The Juan is fishing well into winter
Current Conditions at San Juan:
Winter has arrived, and the Juan is a good choice for those looking to find some fish. The nights are getting pretty cold so expect fish to take a minute in the morning to get going. As the sun warms the water, look for trout to key in on small BWO emergers and midges. Nymph-rigs fished at the appropriate depth are going to find the most fish. There are plenty of opportunities to take fish on the surface still, with decent hatches of Baetis and Midges given the right conditions. Streamer action has been picking up slightly as well. The quality section of the San Juan sees a lot of pressure and after a whole season of fishing, trout are even more selective. Line management, depth and tippet size are all variables to consider. Tippet sizes upwards of 5x are most likely necessary.
The fishing is good. Clear skies and 32-35 degree weather. The water temperature was between 32-35 degrees and Crystal Clear.
