With over a foot of snow this past week, the snowpack continues to build nicely pushing the accumulation to 155% of the median at this time of year. We are nicely ahead of last years accumulation as well so the progress for this year is good so far. The conditions have been relatively mild for winter offering the opportunity to get out onto the river without too much ice buildup. The forecast for the current week is that it will clear in a few days days and as a result the overnight temperatures will drop 20 degrees from where they have been. But the temperatures during the day will be in the mid 30's. This will cause a little more ice buildup along the edges so take care wading.
The snow arrived over the past 3 weeks but the relatively mild temperatures have kept the river clear of ice. However later in the week it will clear and the overnight temperatures will drop towards zero so take care of a possible ice buildup along the edges.
Recommended Flies:Use midges, bwos, and egg patterns.
For mysis at the dam use Mike's Mysis. epoxy mysis, and BDV mysis.
The midges will come off during the day, particularly if it is sunny. So try Wilson's Reverse Candy Cane #20, red and black chironocones #20, nick's larva in miracle pink, olive, and purple back, brassies #18 - #22, midge larva patterns #18 - #22, copper johns #18 - #22, rainbow warriors, black polywings #18 - #22 and bling midges # 18 - #22.
In addition try dry patterns such as the z-wing real midge, black cdc midge and any similar dry black and gray patterns in sizes from #20 through to #26.
The fish are taking generic nymphs such as pheasant tails and caddis larva patterns. The BWO's are coming off as well. Try emerger patterns such as rs2's and WD-50's.
For BWO naturals use standard BWO's, parachute BWO's, parachute Adams, and Thorax patterns.
Current Flow: near Emma - 278cfs (if you want more uptodate figures check out current readings on our "Links" page).
The river has frozen in some places along the edges and the snow has made access more difficult higher up. We are now in winter conditions. Concentrate where the sun is shining. Concentrate on smaller flies, worms and egg patterns.
The Colorado is now in winter conditions. It was frozen over with enough ice during the week to prevent boats launching but with day lkight tempearatures above freezing it is clear where the sun shines longest. Generally head for the wider areas where the sun is shining. Try small flies, streamers and egg patterns.
