winter fly fishing

The San Juan River at Navajo Dam details
The San Juan is a fantastic tail-water fishery that flows cold out from the bottom of Navajo Reservoir. The Juan is the perfect river for full and 1/2 day float or wade trips for all angler abilities. Looking to learn a few of the San Juan secrets? Book an AVA guide to help you decode this technical fishery that is flat-out loaded with trout.

The Juan flows through a true desert canyon with high sandstone cliffs in bench form, each layer exposing millions of years of geology. On the river floor, the river runs slow over shallow riffles and deep pools, and is surrounded by willows, Broad-leaf cottonwoods, Russian Olives and Tamarisk.

Getting There
The San Juan is located about an hour south of Durango Colorado. The city of Albuquerque, Farmington and Pagosa Springs are also a short drive to the river. Albuquerque is about 3 hours, and Farmington is 40 minutes and Pagosa Springs is an hour and some change.

Fly Patterns QW
Midges
Midge pupa vary greatly on the Juan. Most are gray, black and olive. Size range from large #18 to micro #32. Adults are typically black, or black and gray in a # 24 to #30. Various times olive adult will dominate in the same size range. The key to fishing midges on the Juan is being very observant. That goes for size and color for both adults and midge pupa.

Beatis (BWO) BWOs are just important as midges on the Juan. Brown, tan, chocolate and gray wd40s, foam wings, RS2s and Juju beatis are common emergers and nymph patterns. Typical baetis emergers.

JUNK? When the water is clear or stained, various junk patterns can be very productive. Eggs and worms ranging from natural colors to bright reds and oranges will produce. With the water green to clear fish bright patterns above natural patterns.

Larva and red annelids in #18 to #24. Buggers and leeches will also take fish. Leeches in white, gray and black. Some scuds as well in #22 gray.

Lower River
BWOs ranging from #18 to #22 in brown, chocolate and gray. Caddis emergers and pupa in #16. Streamers in black, brown and olive. Vary the size of streamers and experiment your stripping speed.
Eggs and worms.

Predictions and forecast
River will stabilize over the next few weeks. Visibility will remain in the one to 3 foot range for awhile. Fishing should still be good though...just got to get out there.

Trophy Trout Quality Waters
The Quality Water section, located below Navajo Dam in the Navajo Lake State Park,
is one of the top tailwater fisheries here in the US. In the first few miles the San Juan is known for big trout and lots of them. The Juan is home to thousands of fish per mile. Packed full of trout; 10, 25 even 40 hookups per angler, per day is possible.
Fish size averages between 12 to 20 inches. A 16 inch bow seems to be the typical fish these day.

Lower River
The San Juan below the Quality Waters is know as the Lower River, and this section flows over numerous riffles, and is home to a large number of fish. Brown trout tend to out number the bows and they can be very aggressive to a dry or streamer. Fish size ranges between 10 and 15 inches the average seems to be 13 inch browns. But hold on, there are some monster bows and browns lurking about in the lower river. When the river is on, an angler can have a large number of fish to the fly.
