Colorado Stream Update: "Nice to see the sun."

Current Conditions at 11 Mile Canyon:

An overlooked location for Front Range fly fishing is 11 Mile Canyon. We feel the fishery has been very solid the last few years. Nymphing small midges and beatis in the morning was the most productive. As the sun warmed things up in the afternoon, bugs started to hatch and the dry fly bite was on. It was a little on the technical side, but #22 Adams did the trick with some persistence and a perfect drift.

Not too terribly crowded on the river today. Flows have been stable and nymph fishing with small midges and mayflies is the name of the game. We are catching some larger than average rainbows and lots of smaller browns. If you can see a fish you should be able to catch it! Look for rising trout in the pools and eddies.  The fishing is fantastic.  Partly Cloudy skies and 44-47 degree weather. The water temperature was between 40-43 degrees and Crystal Clear.
