Best Winter Fly Fishing Destinations: Where to Cast Your Line in the Cold

Winter fly fishing offers a unique and serene experience, allowing anglers to enjoy the quiet beauty of snow-covered landscapes and often less crowded rivers. While many people pack away their gear during the colder months, seasoned fly fishers know that winter can be one of the best times to catch trophy fish. The challenge of winter fly fishing lies in adjusting techniques to match the slower metabolism of fish, but for those who are up to the task, it’s a rewarding and peaceful way to spend time outdoors.


In this blog post, we’ll explore some of the best winter fly fishing destinations across the U.S. and the reasons why these waters are worth braving the cold.



1. Missouri River, Montana

The Missouri River near Craig, Montana, is one of the top year-round fly fishing destinations, and winter is no exception. Known for its large populations of rainbow and brown trout, the Missouri River offers anglers the opportunity to fish for some truly impressive catches. The tailwater section below Holter Dam remains ice-free during much of the winter, making it an excellent spot to target trout using nymphs and midges.

  • What to Expect: Smaller crowds, clear water, and consistent flows. Fish tend to congregate in deeper pools during the winter months, so slow, methodical nymphing is often the best approach.

  • Best Flies: Zebra Midges, Pat’s Rubber Legs, Scuds, small Baetis Nymphs

  • Why It’s Great: The Missouri River's consistent water temperature and flow make it a great place for winter fishing, with the potential to catch big trout in scenic surroundings.


2. Green River, Utah

The Green River below Flaming Gorge Dam is another top winter fly fishing destination. This river is famous for its gin-clear water, dramatic red canyon walls, and healthy populations of rainbow and brown trout. In winter, the river receives far less pressure from anglers, providing a peaceful and productive fishing experience. The constant flow from the dam keeps the river fishable year-round, and trout feed actively throughout the colder months.

  • What to Expect: Fewer anglers and stunning winter scenery. The Green River's clear water makes it easier to spot fish, but you’ll need to use stealthy presentations.

  • Best Flies: Midge patterns, Scuds, Baetis Nymphs, small Streamers

  • Why It’s Great: The river's stunning beauty combined with its healthy trout population makes it a must-visit, especially during the quiet winter months.


3. Provo River, Utah

Utah’s Provo River, especially the Middle and Lower sections, is known for its strong populations of brown and rainbow trout. Winter fly fishing on the Provo River is ideal for those looking to avoid the summer crowds and enjoy technical nymphing or midge fishing. Thanks to the Provo's consistent flows from the Jordanelle and Deer Creek Reservoirs, the water stays fishable throughout the winter.

  • What to Expect: Crystal-clear water and a mix of pocket water, riffles, and deep runs. Winter fishing means working slow and deep, with small flies often producing the best results.

  • Best Flies: Midges, Sowbugs, and small Baetis Nymphs

  • Why It’s Great: The Provo River offers year-round fishing with reliable access and a steady flow, making it perfect for winter nymphing.


4. South Platte River, Colorado

The South Platte River is one of Colorado’s premier fly fishing destinations, and certain sections like Deckers and Cheesman Canyon remain productive even in the depths of winter. The tailwater conditions keep the water relatively warm and ice-free, and the river’s clear water allows for sight fishing. The South Platte is known for its technical fishing, making it a great choice for experienced anglers who enjoy a challenge.

  • What to Expect: Crystal-clear water and technical fishing. Winter fish are often selective, so small midge patterns and precise presentations are key.

  • Best Flies: Black Beauties, RS2s, WD-40s, Zebra Midges

  • Why It’s Great: The South Platte offers challenging, technical fishing in a breathtaking winter landscape, perfect for those looking to sharpen their skills.


5. Yakima River, Washington

Washington’s Yakima River is the state’s only Blue Ribbon trout stream, and it offers great fishing throughout the winter months. The upper Yakima, particularly the section below the Cle Elum Dam, remains fishable during the cold season, with steady flows and temperatures that support active trout feeding. The Yakima is home to rainbow and cutthroat trout, and winter brings fewer anglers, providing a peaceful setting for fly fishing.

  • What to Expect: Ice-free sections with consistent flows. The Yakima’s trout often hold in slower, deeper water during winter, so fishing nymphs and small streamers is the best approach.

  • Best Flies: Midges, Baetis Nymphs, Woolly Buggers, Stoneflies

  • Why It’s Great: The Yakima River offers solitude, steady flows, and healthy trout populations, making it a fantastic winter fishing spot in the Pacific Northwest.


6. Au Sable River, Michigan

Michigan’s Au Sable River, particularly the Holy Waters section, is a renowned fly fishing destination that remains productive in winter. While the river’s flow slows down significantly during the cold months, the Au Sable’s resident brown and brook trout continue to feed, albeit more sluggishly. Winter fishing here is all about patience and targeting the deep, slow runs where fish hold.

  • What to Expect: Snow-covered banks and peaceful waters. Winter fishing on the Au Sable is best with nymphs and streamers fished slowly.

  • Best Flies: Woolly Buggers, small Streamers, Midge Nymphs

  • Why It’s Great: The Au Sable River offers serene winter fishing in a beautiful, snow-dusted setting, making it an ideal place for those who enjoy a more meditative angling experience.


7. Big Horn River, Montana

The Big Horn River is another exceptional year-round fishery, offering anglers the chance to catch large trout even in the coldest months. The tailwater section below Yellowtail Dam ensures consistent water temperatures, allowing the trout to remain active. Winter fly fishing on the Big Horn is often a solitary experience, with few other anglers on the water. Nymphing and streamer fishing are the most productive methods here during winter.

  • What to Expect: Low angler pressure, crystal-clear water, and a high density of fish. Focus on deeper pools and slower runs for the best success.

  • Best Flies: Ray Charles, Scuds, Zebra Midges, small Streamers

  • Why It’s Great: The Big Horn’s healthy trout population and consistent flows make it one of the best places to fish for large trout in the winter.


8. San Juan River, New Mexico

The San Juan River below Navajo Dam is famous for its world-class winter fly fishing, thanks to its status as a tailwater fishery. The river remains ice-free year-round, and the nutrient-rich waters support large populations of rainbow and brown trout. Winter fishing on the San Juan is all about nymphing with tiny flies and focusing on the deep, slow-moving runs where fish congregate.

  • What to Expect: Large trout, clear water, and technical fishing. The San Juan is known for its challenging conditions, requiring anglers to use small flies and delicate presentations.

  • Best Flies: Zebra Midges, RS2s, WD-40s, small Baetis Nymphs

  • Why It’s Great: The San Juan is a bucket-list destination for winter fly fishing, offering the chance to catch large, hard-fighting trout in a stunning winter landscape.


Winter fly fishing offers a unique blend of solitude, natural beauty, and technical challenges. Whether you’re casting your line in the snow-dusted mountains of Montana or the crisp, clear waters of Utah, these top winter fly fishing destinations provide incredible opportunities for anglers. While the techniques may differ from summer fishing, with patience and the right flies, winter can yield some of the best catches of the year. So bundle up, embrace the quiet of winter, and enjoy the rewards that cold-weather fly fishing has to offer
