The Dolores River near Gateway is a hidden gem, flowing through dramatic red rock canyons and offering a peaceful, remote fly fishing experience. This stretch of river is home to wild brown and rainbow trout, thriving in its cold, clear waters. While flows are low in winter, the scenery more than compensates, and anglers willing to brave the technical conditions can find rewarding fishing opportunities. With sparse hatches of midges and the occasional Blue Wing Olive, this stretch demands stealth, patience, and precise presentations, but the solitude and natural beauty make it an unforgettable destination.
The Dolores River near Gateway offers a remote winter fishing experience in one of Colorado’s most stunning desert canyons. With flows hovering around 40-60 CFS, the water is low, clear, and cold, creating a technical challenge for anglers. Trout are holding in deeper pools and slow runs, feeding predominantly on midges, with the occasional Blue Wing Olive on warmer afternoons.
Late morning to mid-afternoon provides the best window for activity as sunlight warms the water slightly. Nymphing is your most reliable approach, while streamers can coax larger trout from hiding in deep, shaded pockets. The solitude, scenery, and technical fishing make this stretch of the Dolores a true hidden gem for those willing to brave the winter chill.

Seasonal Tip
Low flows and cold water mean stealth and precision are key. Approach pools carefully, use long leaders, and focus on deeper water.
Dry Fly
Look for small midge hatches during midday on sunny days. Target slow eddies and calm tailouts with a light presentation.
Nymphing
A double-nymph rig with a Black Beauty and Zebra Midge is your best setup. Add weight to get down to holding fish in deeper runs.
Streamer Fishing
Streamers like Olive Woolly Buggers or smaller leech patterns can tempt bigger fish. Retrieve slowly through deep pools and along shaded banks.
The Dolores River near Gateway offers limited public access, so anglers should verify boundaries and respect private property. A valid Colorado fishing license is required. Practice catch-and-release and pack out all trash to help preserve this pristine fishery.
