Current Conditions

December 16, 2024

Flows have stayed consistent out of Paco and fishing has continued to be solid. Clarity has been great and water temps are keeping the fish feeding actively. No need to hit the water early in the morning as it has been fishing the best from 11-2PM. Nymphing has proven to be the most productive either under an indicator or tightline. Focus your time on the slower and deeper water with the recent drop in temperatures. Fish have been feeding on baetis, midge, and caddis nymphs in sizes 16-20. On the warmer blue bird days we have been seeing lots of midges and mayflies hatching creating some fun dry fly fishing. Leading your rig with a larger pattern such as stonefly, leech, egg, worm, etc. has been finding fish. Streamers are also never a bad idea on this stretch this time of the year!

Be aware of new regulations on the Northern section of the river, flys and lures only, as well as catch and release. 

FLY RECOMMENDATIONS: #18 Frenchie, #16 Walts Worm, #12 San Juan Worm, #14 Mayers Mini Leech, #18 Zebra Midge, #20 Mole Fly, #16 Two Bit Hooker - Black, #18 Drowned Spinner, #8 Baby Gonga - Black

River Information

The Uncompahgre River, or the “Unc” as it is locally known, births high in the windswept San Juan Mountains and slogs northward through the towns of Ouray, Ridgway, and Montrose as it makes its 75 mile voyage toward a marriage with the Gunnison River in Delta.  The premiere stretch of the Unc is the tailwater below Ridgway Dam in Ridgway State Park known as Pa-Co-Chu-Puk or “Paco.”  Paco is a tremendous year-round trout stream which boasts wild brown trout, a hodgepodge of wild and stocked rainbow trout, and Snake River cutthroat trout brood fish.  This tailrace easily exceeds the qualifications for Gold Medal Water and excels in the winter when other fly waters are hibernating and during runoff when other trout streams are roiling with high, chocolaty water.

     Further downstream, the Uncompahgre River runs through the town of Montrose and may be the best kept fly fishing secret on the western slope of Colorado.  The town stretch of the Unc offers great fly angling for browns, rainbows, and cutbows, especially during fall, winter, and early spring.  A couple of the best locales within Montrose are behind Home Depot and Riverbottom Park, but there is quality fly fishing throughout the town stretch.  Although the average fish size is much smaller, 20-plus inch trout are not uncommon.  Surprisingly, despite having high numbers of brown trout, and some hefty ones, the Unc is not regarded as an overly productive streamer fishery.

Seasonal Conditions

Spring

Spring

The early season is a good time to angle both Pa-co-chu-puk and the Montrose stretch of the Unc due to relatively uncrowded conditions, increasing bug activity, and increasingly active trout. High water typically sullies the town stretch from late April throughout the first half of June, while Paco remains fishable. Nymphing with midges, BWOs, or caddisflies is a productive tactic and you might even experience a heavy BWO hatch on overcast, drizzly days.

Summer

Summer

Pa-co-chu-puk can be busy in the summer as there are over 200 campsites within a spey cast of the river, but the Montrose town stretch of the Unc can provide you a respite from the hordes of wader-clad humanity. Paco's most interesting summertime hatches are PMDs and green drakes and big fish can be duped on dries. Downriver, green drakes don't play much of a role but blanket caddis hatches and golden stoneflies give anglers options for both nymphing and dry fly fishing. Trout in the town stretch are notoriously easy to capture with nymphs.

Autumn

Autumn

Dam releases out of Ridgway diminish substantially in autumn allowing for excellent sight fishing for big fish at Paco. PMDs and BWOs keep trout looking up until mid-October, but leeches possibly bring more quality fish to hand than any other offering. This is a fantastic time to catch your biggest brown trout of the year throughout the Uncompahgre River. In the town stretch, trout will still rise to small hoppers though nymphing with a big stonefly followed by a small mayfly imitation will likely produce more consistent results.

Winter

Winter

The Uncompahgre River, from Paco downstream through Montrose, remains mostly ice-free throughout winter. Late season is possibly the best timeframe to enjoy this river’s piscine pleasures. To find success with low, clear water you need to avoid cavalier wading, make gentle and accurate casts, and possibly reduce the size of your flies down to a size 20-24. Target the slow, deep pools which will often require blind casting. Wintertime provides you an opportunity to catch your best ‘bow of the year on the Unc.
