Colorado Stream Update: Cheesman is fishing well as of late - Look for flows to drop soon

Current Conditions at Cheesman Canyon:

Cheesman canyon has been fishing well lately! There have still been some reports of fish being caught looking up on terrestrials, so a hopper-dropper rig isn't a bad place to start. As we move into fall and Denver Water begins to move water around to satisfy demand flows should drop. Small tippet sizes and presentaion are going to make the difference. Some risers are being spotted in the soft water but most eats remain subsurface, so a light nymph-rig should find the most action. Mercury baetis, JuJu's, and top secret midges has been finding fish consistently. RS2's, Barr's emergers, and small hare's ears are also good flies to sample.

Make sure you have a quality set of polarized glasses. The public water sections are producing better than average fish and good fly fishing reports.  The fishing is great.  Clear skies and 60+ degree weather. The water temperature was between 56-59 degrees and Crystal Clear.
