Best Fishing Spots

The Blue River below Green Mountain is a must-visit for fly-fishing enthusiasts, characterized by its stunning landscape, excellent water flows, and plentiful trout stock. Some of the best spots include:
  • Green Mountain Tailwater: Just below the dam, it offers amazing fishing year-round, thanks to its regulated water temperature.
  • Tumble Creek Confluence: This picturesque spot has plenty of large trout hiding in its deeper waters.
  • Spring’s Gulch: Ideal for wading, it gives a high chance of landing brown and rainbow trout.
  • Blue River Campground: Excellent fishing opportunities, surrounded by scenic vistas and accessible camping facilities.
  • Columbine Landing Access: Known for its big brown trout, this quiet section is less frequented by anglers.
Remember, like most fly-fishing waters in Colorado, the Blue River operates under Gold Medal Water Regulations for certain stretches, meaning all fishing is catch-and-release.

Best Access Points

The Blue River below the Green Mountain offers some excellent spots for fly fishing. Accessible and well-stocked, it’s a favourite among anglers. Here are the best points to access the river:
  • Cowboy Park: Accessible by a well-marked trail, offering large sections of the river for fishing, especially for beginners.
  • Green Mountain Reservoir: The area below Green Mountain Dam provides abundant opportunities to catch trout and other fish species.
  • Blue River Campground: Excellent for fly fishing with easy water access and ample camping facilities.
Before heading out, always check local regulations and ensure you have the correct permits. Be aware that portions of the river run through private property, so always respect property rights while accessing these fishing spots. Also consider hiring a local guide to learn about the best fly fishing techniques and navigate the river safely.

About The River

The Blue River, a key feature of the stunning landscapes beneath the majestic Green Mountain, has a rich and fascinating history that stretches back centuries. This magnificent waterway originates from the snowmelt of the mountainous areas that surround it and presents a breathtaking sight as it takes its course against the backdrop of Green Mountain.

A few key historical points about the Blue River include:

  • Native American tribes, particularly the Ute, initially inhabited the areas around Blue River, using this waterway for sustenance and transportation.
  • During the 1859 Colorado Gold Rush, prospectors discovered gold along the river banks, transforming the Blue River into a bustling hub of activity.
  • In the 1940s, numerous dams were built along the river for electricity production and water supply, helping to shape the landscape and economy of the region.

Today, the Blue River underneath Green Mountain stands as a remarkable testament to human history, natural beauty, and continual evolution.
