San Juan River

Flows are falling quickly, and the river is clearing up. Fishing should be pretty good with caddis and stoneflies coming off. Nymph rigs will still be the best bet, but its about time to start throwing dries too. Dry/dropper setups with a stonefly dry and nymph or caddis pupa/emerger will be a fun time.

Patterns/Bugs:
Pats Rubberlegs in 4-8. Jigged Pats Rubberlegs #8-12, 20 Incher Stone #8-12, Epoxyback Golden Stone Nymph #8-12.
Black Buggers 2-6, Mini Sculpin Black and Natural #6-10.
Stonefly Dries: Stimulators #6-12, Rogue Foam Stone #4-8, Sofa Pillow #4-10.
Caddis #14-16: Barrs Graphic Caddis, Prarie Dog Pupa, RIOs Big Boned Caddis, Elk Hair Caddis, Parachute Caddis

Flows have been steady and the water is clear, but fish are feeding good.
Bugs are on the menu. Midge and baetis nymph rigs are a good setup to start. However, you can expect midge and BWO hatches to come of late morning through the afternoon.
The ant fall happened early June already, so it would never hurt to have a few ant dries all summer.

Patterns/Bugs:
Midges 20-26: Black Flash Midge Pupa, Tavs Big Mac, Bling Midge, Grey and Olive Midge Pupa.
Midge Dries: Griffith Gnat 18-22, Bunny Midge 20-24.
BWO Nymphs: Foam Wing RS-2s 20-24, Killer May 20-24, Juans Sniper Baetis 22-24, Juans Jedi Master 22-24, All Flavors of WD-40s #20-24.
BWO Dries 20-24: Parachute Adams, CDC Comparadun, Vis A Dun, Baetis Parachute.
Flying Ants 12-16: Para Ant, CFO Ant, Black Big Boned Caddis.

It seems the flows are rising again after a few days of cooling down. Fishing may be good, and float fishing is an option but wont last long.
Dark streamers and stonefly nymphs are the go-to, but possibly stonefly dries will be about.

Patterns/Bugs:
Pats Rubberlegs in 4-8. Jigged Pats Rubberlegs #8-12, 20 Incher Stone #8-12, Epoxyback Golden Stone Nymph #8-12.
Black Buggers 2-6, Mini Sculpin Black and Natural #6-10.
Stonefly Dries: Stimulators #6-12, Rogue Foam Stone #4-8, Sofa Pillow #4-10.

So, I dont want to alarm you, but if you were to float the upper San Juan, right now would be a good time. Its dropping quick and the flows will only hold a few days. Dark streamers and stonefly nymphs are the go-to, but possibly stonefly dries will be about.

Patterns/Bugs:
Pats Rubberlegs in 4-8. Jigged Pats Rubberlegs #8-12, 20 Incher Stone #8-12, Epoxyback Golden Stone Nymph #8-12.
Black Buggers 2-6, Mini Sculpin Black and Natural #6-10.
Stonefly Dries: Stimulators #6-12, Rogue Foam Stone #4-8, Sofa Pillow #4-10.

Clear water right now means spookier fish. Spookier fish means you must dial your flies, depth, and rigging just right.
Bugs are on the menu. Midge and baetis nymph rigs will be the number one right now. Expect some midges to hatch late morning, and a few BWOs around noon.
Summer rains seem to come earlier each year, so be prepared with a few flying ant patterns in June

Patterns/Bugs:
Midges 20-26: Black Flash Midge Pupa, Tavs Big Mac, Bling Midge, Grey and Olive Midge Pupa.
