Upper San Juan
The upper Juan flows down from the Continental Divide and heads south through
Pagosa Springs Colorado. South of Pagosa the river tumbles for 12 miles through
the incredible Mesa Canyon before flowing into the mellow valley made up of wide
canyon walls and ranch land. Another 20 plus miles down river the upper Juan
grinds to a halt in Navajo Reservoir.
access for wade fishing
can be found through
Pagosa Springs. Most
of the water located
north and south of Pagosa
is private, so float
fishing is the best way
to experience this river.
|San Juan (Pagosa Springs)
The upper Juan, as we call it, is like a mini Green River. Big spring and early summer hatches make for fat fish and fun fishing. There is a float season in June, but fantastic wade fishing at other times. The fish respond to large and small fly patterns depending on the conditions and season.
Upper San Juan (near Pagosa Springs) Guide Report, Flows and Hatches
The Upper Juan typically gets low and very cold with marginal fishing opportunities in the winter. From time to time you will find open water in town and a maybe a willing fish. Before it ices and becomes snowed over a few fish will grab eggs, worms, midges, BWOs and buggers.
The upper Juan is very low and iced over. We will not see increased flows till early spring.

Fall can be great, as long as flows are stable and not muddied by late season monsoon rains. Like the Piedra, it is very easy to muddy with wet weather. When it has been clear plenty of fish are being fooled by short nymph rigs, hoppers and streamers.
