Blue River
About
Gold Medal waters below Dillon Dam support trophy trout populations that earned the Blue River its designation in 1998. This 65-mile White River National Forest drainage flows north through Summit County at 450 CFS average, with optimal flows between 200-1500 CFS. The Ute established summer camps throughout the Blue River Valley before European contact. Above Dillon Reservoir, the mountain headwaters from Breckenridge run Class I-II through high country meadows. The tailwater section below Dillon Dam to Green Mountain Reservoir maintains the cold, consistent flows that created the Gold Medal fishery. Below Green Mountain Reservoir, the river enters a canyon run with Class II-III rapids before joining the Colorado River. Breckenridge Outfitters guides the upper sections. USGS gauge 09046600 tracks conditions for both anglers and paddlers working this drainage.
River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
