Willowfly Anglers's Tip of the Week

The Gunnison River is currently reading 300 CFS in Gunnison. With the water crystal clear, eyes and heads are coming to the surface! That means Dry Flies, and Dry Droppers. Hopper patterns or Chubby Chernobyl with a dropper behind are working great! keep the heavy flies short, and those with lighter weight looong. Float fishing is still going on, and we are getting some nice fish on the drift, so book those float trips while we still have availability and water to float! Also the wade fishing has been fantastic this season. We are also seeing some of our late summer hatches already happening. We have had some reports of Trico's already popping off on the Gunnison Streamers in the morning has also been a fun and productive way to start the day! Double Gonga in Black, kreelex, Cousin It, and Micro Peanut Envys in black have been fun to throw! With the low water please keep an eye on the afternoon temperatures, especially down low on the Gunnison River towards Blue Mesa. We recommend pulling lines in and calling it a day once water temps get to 66F. Give us a call for the most up-to-date report. Tight lines everyone!

Description: About Upper Gunnison River

The Gunnison River begins at Almont, Colorado, where the Taylor River and East River merge to form its headwaters. The river grows in size as it flows down through the Gunnison Valley and into Blue Mesa Reservoir. This is the first of several dams as the Gunnison continues its flow through the Black Canyon and eventually into the Colorado River. Our section of the Gunnison River, the upper Gunnison, is from the headwaters in Almont to Blue Mesa Reservoir. The East River is a freestone river which drains out of Emerald Lake, which is located at 10,500 feet in the Rockies near Crested Butte. So the upper Gunnison is impacted by both snow-melt and the controlled releases from Taylor Reservoir. The Gunnison is best fished from a boat in the early season during high water. There are also plenty of public access points for wading the river during summer and fall. The Gunnison River contains a very high density of trout, including browns, rainbows, and cutthroat. There are long riffles and runs, and deep pools which hold large trout. There are good hatches of stoneflies, caddis, and mayflies during the season. The peak season is from mid June to late September, and fall fishing can be spectacular on the Gunnison. The fall kokanee salmon run brings hard-fighting kokanee salmon up the Gunnison River from Blue Mesa as they run to the Roaring Judy fish hatchery on the East River. There is a catch-and-release season for kokanee from August 1 to October 31. Big trout will follow the salmon up to feed on their eggs. A 9-foot 5-weight fly rod is a good all purpose choice for the Gunnison River. A 6-weight rod can also be used for heavier nymph rigs and/or for streamers.
