High Water Fishing Report

San Juan River Fishing Report & News

Fisheads of the San Juan’s Fly Fishing Tip of the Week

The river is running at 4000cfs This is for channel maintenance and to rid the lake of excess water from all the snow in the Mtns. The water is getting clearer daily! We have 3 to 4 feet of visibility, and the fishing is getting very good! Time to come and fish. We are doing well in the guide boats! We are still catching fish using large attractor patterns and bright colored larvae. The water is going to 5000cfs by the end of the week. Wading the river will be just about impossible until the flows come back down in the middle of June. The fishing is historically very good as the water comes back down so try to get here after June 16th if you are looking to wade fish the river. The fishing in the boats during high water has been very good to excellent. The fish are eating like crazy on all the food that has been flooded. The water is very fishable during the release and often produces lots of large fish. Come if you can and experience the river like you have never seen it!

5-Day Outlook

The weather this week is looking partly cloudy to sunny with highs in the 80’s. The water is coming up due to all the snow we got in the Mtn’s this year. It will go to to 5000cfs by Friday. Fishing is great out of the boats but very limited wading access. It will start dropping back down in the middle of June. Fishing is very good during high water as the water is still clear.

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. The fish are eating lots of midges, fish short light rigs. 8-10 size weights with a strike indicator set at 2-3 ft. 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 mayfly 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 blue-gray 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.
