Colorado Stream Update: Summer in Estes

Current Conditions at Big Thompson:

The Big T is seeing lots of pressure right now. Estes Park always gets hit with lots of summer traffic. For best results fish early and late in the day. Flows are still up around 300cfs which is fantastic for this time of year. Streamers can be very effective in the canyon during the summer months. Sculpzillas and sparkle minnows are my favorite.

The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 60+ degrees and Crystal Clear.
