Brown Trout
Dillon, Colorado, offers excellent brown trout fishing in the surrounding rivers and streams. The Blue River, both above and below Dillon Reservoir, is a prime location. The tailwater section below the dam maintains consistent water temperatures, making it productive year-round, though winter fishing can be challenging due to ice. The upper reaches of the Blue River, as well as smaller tributaries like the Snake River, provide more classic freestone river fishing. Browns in this area tend to be opportunistic feeders, so a variety of flies and lures can be effective. Streamers can be particularly effective for attracting larger browns. Access to the Blue River is readily available along Highway 9. Be mindful of private property and respect posted signs. A local tip: check the water flows before heading out, as releases from Dillon Dam can impact fishing conditions significantly. Targeting the seams and eddies is key to finding where trout are holding.
