Winter on the Lower Colorado River near Grand Junction is a choose-your-own-adventure kind of fishery. Some days, you’ll find steady action with willing trout, while other days, the fish will make you work for every bite. With stable winter flows and mild temperatures, this stretch is one of the most productive cold-season fisheries in Colorado, especially if you know where to look and what to throw.

Tips for Fly Fishing the Lower Colorado near Grand Junction

Seasonal Tip

Cold water slows down trout metabolism—focus on deeper, slower water, and don’t be afraid to dead-drift bigger stoneflies or streamers.

Dry Fly

Midge clusters may bring up a few risers in slow backwaters, but dry fly opportunities are limited.

Nymphing

A double-nymph rig with a stonefly and small midge pattern is your best bet—adjust weight frequently to stay in the strike zone.

Streamer Fishing

Go big and slow—a dead-drifted or slowly stripped sculpin or minnow pattern can move a hungry brown.
