The Blue River North of Silverthorne town limits contains some beautiful public water and breathtaking views. Unfortunately, it does not boast the highest trout population in some of its public sections. This does not mean there are no fish to be caught, but you may have to be patient and work a little harder to hook up. However, you do always have the shot at hooking the fish of a lifetime, a large trout that usually reside in private sections of the Blue sometimes venture into public waters. Happy hunting.
River Flow (Cubic Feet Per Second):
Flows are currently between 100 - 300 CFS north of town. It depends where you are since there are lots of feeder creeks between Silverthorne and Green Mountain Reservoir.
Water Temperature ( Degrees F):
Mid 40's - low 50's
4' plus feet on most days, but as you get closer to Green Mountain Res the water has more potential to be off color due to feeder creeks.

guide tip of the week:
River flows have come up 50 CFS, but these flows are still on the low end of the spectrum. Medium sized beadhead nymphs in combination with small, natural imiations of midges, Baetis, and Yellow Sallies can be effective at this time of year. As temperatures continue to warm expect fish to start feeding more in the upper water column, and in shallower water.
If we see a large boost in flow from Dillon reservoir, or heavy precipitation/snowmelt the water North of town . Larger beadhead/weighted nymph patterns, streamers, and worm patterns can all be effective during these times. Running a small streamer underneath your bobber as the bottom fly can also be deadly and produces some dramatic strikes when its on!
We love seeing and hearing about your outings as well. Send any fishing photos or stories you want to share over to firstname.lastname@example.org and we'll throw 'em up in the reports.
