San Juan River, New Mexico Fly Fishing Reports & Conditions
My tips of the week
The San Juan River is flowing at about 700 CFS. Midge fishing has been doing well through out the whole day. Midge larvae in grey, cream, olive, rusty brown and olive brown are working. UFO's, Big Macs, Sidewinders and other similar patterns are doing good. Adult baetis are starting hatch in the later part of the day, but emerger patterns are still doing very well. Use emergers as a to fly and midge larva patterns as a bottom fly. Juju Baetis patterns in black and other darker colors are fishing. Sidewinder patterns are another good bug imitation. Stick to sizes 22-26 right now, even for dry flies. There are some PMD and other adult hatches occurring so keep an eye out for bugs coming off the water. If you want to fish dries, use patterns like mayflies, parachute adams, bwos, etc. Look for what color the bugs on the surface or flying around might be to help determine what you need to tie on. Hoppers are occasionally catching fish, try darker colors first.

Techniques & Tips

Fish fluorocarbon tippets at the end of your mono-filament leader when nymph fishing. 5X to the first fly and 6X to the dropper. This will produce more strikes as the fish can't see the fluorocarbon. Fishing 22 to 24 midges in the slower waters has been great, Fish slightly heavier weight ( a number 4 or 3 ) since the river is a bit higher, with your strike indicator 3 to 5 feet above the weight. We are finding lots of baetis, especially on cloudy afternoons. Baetis live in fast water so look for them in the riffles at the top of holes and at the bottom of holes in the tail out. Fish are eating gray, red, olive and brown nymphs in these places, it just depends on the day so have them all. You may have the chance to see fish on top during this time. A parachute Adams or comparadun should do the job. The may flies are green and are about size 22. Use dark colored wings as the fish are turning away from white wings. If you can't see this try a marker fly about 12 inches above the baetis. You should fish mono-filament tippets when fishing on the surface as fluorocarbon sinks. Change back to midges when the fish stop eating your may flies. Try some bunny leaches if all else fails. Dead drift them like the rest of your nymphs. Fish are eating them for moss! They will shake the drifting moss to get the bugs out. All this goes out the door when fishing streamers. Get them on the bottom and fish 1X fluorocarbon.
