The Colorado River is the main watershed for much of the American Southwest. It runs 1450 miles from high in Colorado’s Rocky Mountain National Park to its delta in the Gulf of California near Sonora, Mexico. The upper portion of the river from Granby, Colorado to below the town of Rifle is an excellent trout fishery that holds a healthy population of brown, rainbow, and native cutthroat trout. Most of our fishing trips to the Colorado are with either a drift boat or raft because it is a large, deep waterway with roaring rapids, steep canyon walls, and treacherous, rocky banks. The rugged beauty of the Colorado River is unmatched, and is sure to inspire and captivate even the most seasoned fly fishermen.

If they don't seem to be fully rising to your dry, try throwing and emerger like an RS2 or remote control behind your dry.  Let it swing too!

Keep Em Wet: If you must take a photo, leave the fish in the water.

The Colorado is flowing just above 400 cfs on the Kremmling gauge due to recent rainstorms.  This is causing clarity to be an issue up and down the river. This weekend we should see an increase in clarity, but may see a drop in flows.

On the Upper Colorado, streamers and deeper nymph rigs have been more productive than anything.  We are seeing BWOs on cloudy days, midges, and tricos as well.  Streamers have been very productive on the days when the water is a bit dirty.
