Cheesman Canyon is one of the best tailwaters in the country. There’s a common belief among “canyon regulars” that if you can catch fish on the South Platte River, you can fool fish anywhere in the world. There’s no substitution for good technique in Cheesman Canyon.
Flow: 199 cfs
Water Temperature: Low 50’s in the upper canyon, but the river warms quickly as it moves downstream. Denver Water is closely monitoring stream temperatures to keep them between 50 and 60 degrees.
Hatches: Midges, blue-winged olives, yellow sallies, golden stoneflies, and caddis.
14 Day Forecast: Look for sporadic hatches of PMD’s, caddis, and Tricos. Denver Water will keep the water between 50 and 60 degrees by releasing water from the bottom and mid-level valves. Conditions should be ideal for weeks to come.
Tips and Other Information: Class is back in session in Cheesman Canyon. The Cheesman trout are once again eating the “small stuff” and fishing has tightened up a bit. Anglers willing to work hard, however; reap the benefits of some quality trout! Fly-fishers can expect to find a few trout rising to blue-winged olives, Tricos, and PMD’s. Target the slower pools and tailouts if you are looking for risers. The dry fly fishing has been quite good if you look in the right areas! The golden stoneflies continue to emerge but the hatch is winding down quickly. Amy’s Ant is still picking up a few fish, but not in the same numbers as a few days ago. Looking ahead, it’s time to fish with tiny midges and Baetis nymphs again.
