San Juan River Fishing is great, there are midges everywhere and they are hatching up and down the whole quality water section. The fall BWO hatch is also coming on strong. Start looking for them around noon. Fishing the midge hatch in the morning with olive, gray or black midges is very good. . The afternoon has been my favorite with lots of fish looking for baetis. Chocolate, olive or gray have been best. The slowest time of day seems to be around 11:00 to 12:00. Cloudy days are the best. As always a large part of your success will be your in ability to move around to where the hatches are coming off the best. Fish near the dam in the best midging waters to start,most of the midges are very small. I have been doing well with a black larvae or pupa to a gray or olive larvae. Around 12:30 move down to where the baetis are hatching, anywhere from lower Texas hole down to the end of bait water. The afternoon baetis hatch is coming on strong. Dry fly fishing is still good. The whole river is fishing well,. Watch out for moss on your flies, you have to keep them clean. There are both brown and rainbow trout spawning in the river and salmon at the lake so egg patterns are working well.

The hatch is best on cloudy days. Dark or light gray, brown and olive have been the best colors in a size 20 and 22. Both dry and wet patterns.

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 light weight ( a number 6 or smaller ) with your strike indicator 2 or 3 feet above the weight. You don’t want to be on the bottom when you are midge fishing. 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, 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.
