The Upper Dolores is a cool river, but the best fishing will be around the town of Dolores with streamers and nymphs. As you move upriver towards Rico, access will become more difficult with snow, but it will start to open up with spring. Watch for flows to bump with runoff.
Patterns/Bugs:
Nymphs: Prince Nymphs 14-18, Pats Rubberlegs 8-12, Duracell 12-16, Rainbow Warrior 18-22, Pheasant Tail 16-20, Zebra Midge 18-22.
Buggers and streamers in olive, black, white.
Wadeable flows at about 75 cfs out of the dam still and going strong.
Fishing will be picking up, you will need to hike to get close to the dam and better fishing. The flows are better then they have been in years past, so fish may spread out.
Early season is midge and mayfly world, which can be good. Watch for Baetis hatches midday. It wouldnt be a bad idea to bring your streamers either.
