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.
Water Temperature: Low 40’s
14 Day Forecast: Look for hatches of midges, sporadic caddis, golden stoneflies, craneflies, PMD’s and blue-winged olives.
Tips and Other Information: Cheesman Canyon is fishing tough right now with the recent drop in flow. Cheesman Reservoir is extremely low (58,000 acre feet) so look for low flows for the remainder of the year. Denver Water is gonna leave the Roberts Tunnel on this winter (so that means lower flows on the South Fork), so look for flows to range between 50-100 cfs for most of the autumn and winter season. Anglers can expect to see a good a.m. midge bite, followed by mid day mayflay hatches. First the Tricos come off, followed by some blue winged olives. Go-to bugs have been size 20 Jujubaetis, size 22 Stalcup’s Baetis, and a size 22 Foam Wing Emerger. You’ll find plenty of rising fish if you target the right water and really look for them. Crowds have been very heavy as of late…
