Colorado Stream Update: Mysis Shrimp are on the menu on the Blue through Silverthorne!

Current Conditions at Blue River Below Dillon:

The flow coming out of Dillon Reservoir is now in the low-200s cfs, which is up from it's winter flow, and with this the famed Mysis are really pumping through the river. These trout aren't really looking up at the surface quite yet so it's wise to keep with the nymph rig on. Mysis patterns, red Disco Midges, Black Beauties, and Pheasant Tails are all working well right now. With the high flows, trout are more spread out, but still very close to banks and behind structure.

The weather is warming up outside and it is beginning to look like spring again! Due to the spawning fish, fishing egg patterns can be quite productive. Runoff is just around the corner so be sure to get a few more beautiful spring days on the water.  The fishing is good.  Clear skies and 48-51 degree weather. The water temperature was between 36-39 degrees and Crystal Clear.
