About Blue River
Gold Medal tailwater below Dillon Reservoir in Silverthorne. Trophy rainbow trout up to 24"+ on Mysis shrimp — use Mysis imitations year-round regardless of what's hatching. Consistent regulated flows make it one of Colorado's most reliable cold-weather fisheries. Can be crowded on summer weekends.
