Colorado Stream Update: "That is one of the biggest suckers I have ever caught here. Sucker King!"

Current Conditions at 11 Mile Canyon:

Fishing has been pretty awesome. Like many of the tailwaters on the Front Range, it still is not a gimme, but it has been excellent. Nymph baetis, midges, and caddis pupae until you see a hatch of tricos or caddis. The surface bite is not on fire but you can take a few fish with a good draft. Watch out for crowds here, and try to hit this section on a week day.

Make sure you have a quality set of polarized glasses. Guides report that the sight fishing has been fantastic. Blue and black midges are hooking lots of pigs. The public water sections are producing better than average fish and good fly fishing reports. Winter is around the corner and the crowds on the South Platte should be dying down a bit.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 48-51 degrees and Crystal Clear.
