The Blue below Dillon Reservoir has been fluctuating between 70 cfs and 120 cfs over the past 10 days or so. The late mornings and afternoons have seen relatively steady flows as the powers that be have usually been making their changes to the flows during the off-peak fishing hours.
Best technique has been nymphing under a small, inconspicuous indicator. Seeing rising fish is a possibility as is seeing some action on streamers. Your best chances for success using dry flies will typically occur early in the morning and during the warmest part of the day. Streamer action has been best during low-light conditions.
Question: What's going on with the Gold Medal status of the Blue River?
Answer: The Blue River between Silverthorne and Green Mountain Reservoir has been delisted from Colorado's Gold Medal list. The Blue within the city limits of Silverthorne is still listed as Gold Medal water. There are still great fish to be caught from Silverthorne all the way to Green Mountain Reservoir (and below). If you check in with us regularly, you have seen hundreds of photos of fish that were caught in this stretch over the years, and many that were caught (and released) this year. It's true; you won't find the numbers of fish north of Silverthorne that you will see in Silverthorne. But you will find fewer anglers and less selective fish!
