The Blue River starts in Breckenridge and goes all the way to Kremmling, passing Dillon Reservoir and Green Mountain Reservoir. The best place to fish the Blue River is in Silverthorne, where there is public land to fish on and plenty of spots to wade out into. The Blue River is quality freestone and tailwater fishery consisting of brown, brook, and the enormous rainbow trout found below Dillon Reservoir. Beautiful pools, deep runs, and classic riffles characterize the river from Dillon Reservoir to Green Mountain Reservoir. Boulders, bends, and depressions in the river bottom account for the variety of seams and excellent holding habitat for the trout. The river averages from 80-100 feet across, flowing through the Gore Mountains to the Colorado River near Kremmling. Below the Reservoir, is a tailwater fishery where monster trout feast on the thousands of mysis shrimp spilling out of dam. Keep in mind that fish caught in the town of Silverthorne must be released immediately.
Colorado Highway 9 runs parallel to the river all the way to Kremmling, there are numerous parking areas along this highway and you can find a spot with the big ‘P’ signs spotted all over. There are even sign telling you about the fishing regulations in these areas. Several National Forest easements, clearly marked by Division of Wildlife signs, access the river. Quality angling can be found all the way to where the Blue meets the Colorado River. The water level in the Blue varies a lot, due to release from the dam, so check the stream flow level before you go. Waders are nice to have, but not always necessary. This river never gets too deep, but it can get darn swift when water levels are up.
The Blue River area south of Dillon Reservoir are usually on private owned land and difficult to find a good spot, whereas the areas north of Green Mountain Reservoir are usually restricted for security reason, your best bet for some solid fly-fishing is in Silverthorne along Highway 9! There are also the Blue River Ranch Lakes that are usually off limits to the public, but there are some areas to fish. If you get bored of fishing, just walk on over to the Outlet Mall and do some Shopping or head back to your vacation rental in Keystone for some continued R&R!
