Fishing Season: Year Round

Chris Taylor, Fisheads of the San Juan's Tip of the Week

The San Juan is going to have excellent flows and cold water throughout the season. The lake and river are in great shape. Times of drought are what this reservoir is made for! The river is running at 940cfs. The river will remain at this flow for a couple of weeks as there is a release of water scheduled. The water is still slightly turbid from all the rainwater that entered the lake last fall and normal winter lake turnover. The river has been clearing quickly. Fishing has been excellent! Fish worm imitations and egg patterns. Bright colored larvae should also work well. As you start to see midges or baetis later in the day fish more natural patterns like dark gray midges and dark brown RS2's. We are starting to see caddis and PMD's on the lower river. The ant fall usually happens sometime between June and the end of July. Dry fly season is upon us!

5-Day Outlook as of 6/8/26

The weather this week is mostly sunny. It is going to be in the high 80's to low 90's this week. Back to Summer conditions. Any cloudier days will produce some big hatches. Don't be afraid to throw some realistic insect imitations, the fish will be looking for them. It is cool in the mornings and warm in the afternoon so wear layers you can take off. This weather is producing some great blue winged olive hatches in the afternoons. I have seen some great midge hatches lately with a few fish finding clusters of them on top. Streamer fishing has been good in the quality water. The CFS will be changing throughout the year trying to keep at least 500cfs in Shiprock NM.

Techniques & Tips as of 6/8/26

Fish fluorocarbon tippets at the end of your mono-filament leader when nymph fishing. 4X to the first fly and 5X to the dropper. This will produce more strikes as the fish can't see the fluorocarbon. Fish an attractor fly like a bunny leach or an egg pattern to a colored larvae or a fly with flash on it. 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.

Description: About San Juan River

Located in the northwest corner of New Mexico, 40 miles South of Durango, Colorado and 30 miles Northeast of Farmington, New Mexico. The San Juan River is world renowned for providing some of the most rewarding trout fishing you will ever experience. The San Juan is a consistent producer of both rainbows and browns averaging 16 to 18 inches, with many reaching much larger proportions. Recent studies have suggested that there are 15,000 fish per mile. Since the completion of the Navajo Dam in the early 60's, the river below the dam has provided a perfect environment for the growth of trophy sized trout. Brown trout naturally reproduce in the river and the rainbow fingerlings that are stocked yearly are essentially wild by the time they reach maturity. Catching them is an experience you will never forget! The San Juan has developed a far reaching reputation for Gold Medal trout fishing throughout the year. With comfortable temperatures all four seasons, you can be assured of enjoyable fishing whenever you come. The San Juan provides something for everyone, year round. Clothing should be layered so you can adapt to the widely varying temperatures. Afternoon rain showers are common also. Rain is common in the summer. Bring a rain jacket even if the sky is cloudless in the morning. Sun block (SPF 30+), sun gloves, hats, neck protection, polarized sunglasses and sun protective clothing are highly recommended.
