The lower Colorado River near Grand Junction offers a unique fly fishing experience amidst Colorado's high desert landscapes, blending mild winter weather with excellent fishing opportunities. Flowing through scenic stretches near Fruita, Connected Lakes, and the Colorado River State Parks, this section is characterized by its slower runs, deep pools, and clear water.

Updated: 11/26/2025
Flows held steady this week and clarity has improved after the color swings earlier in the month, giving the lower stretches a more stable winter personality. Fish are sliding into slower, deeper troughs along the banks, with midge and light Baetis activity driving most of the eats. Pressure remains low, and with colder night temps in the valley, you’ll find trout waking up late and feeding tight to structure. This stretch can look big and intimidating, but the productive water shrinks dramatically in winter if you focus on soft seams and slow shelves. Expect fewer rising fish, consistent nymph eats, and the occasional streamer chase if you crawl it through deep buckets.
