Fishing is picking up with the warming weather, but so are the flows. Discolored water can cause fish to move to bigger nymphs.
Patterns/Bugs:
Nymphs: Prince nymphs 12-16, Pats Rubberlegs 6-12 or Jigged Pats 8-14, Black and Copper Copper Johns 12-16, 20 Incher 10-14, Pheasant Tails 18-22, RS-2 18-20, Rainbow Warrior 18-22, RS-2 18-20, San Juan Worms. Zebra Midge or Poison Tung 18-22
Dries: Vis-a-Dun Baetis 18-22, Smoke Jumper Baetis 18-22, Parachute Adams 16-22.
Flows are steady on the old Juan at just over 500 cfs. Fishing has been decent with annelids, midges, and leeches. A Mayers Mini leach with a bling midge, or annelid/RS2 good go-to right now. Water is a little off-color, attractors and junk flies may be necessary. Of course, streamer fishing is better than you may expect earlier in the morning
