The predicted cold weather arrived and caused a buildup of some anchor ice in the wider, shallower sections of the rivers. The cold weather seems to have passed with the prediction of temperatures back up to the mid 40's during the day and some cloud cover arriving to keep overnight temperatures a little less cold. Generally it is predicted to be a mild week with little snow. Another 20" of snow this week, has added nicely to the snow pack.
It will be a good week for fishing with the temperatures relatively mild for this time of year so if you get a chance to get out onto the river it should be excellent.
The cold over the past week added some anchor ice in the slower wider sections and some ice on the edges. So take care wading. With a relatively mild week predicted, the fishing should be good during the middle of the day.
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 well into 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 light temperatures above freezing it is clear where the sun shines longest. So generally head for the wider areas where the sun is shining. Try small flies, streamers and egg patterns.
