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.
14 Day Forecast: Look for low flows until Cheesman Reservoir fills. Anglers can expect strong hatches or midges and sporadic Blue-Winged Olives.
Tips and Other Information:Flows are low considering the time of year. Cheesman Reservoir is 18,000 Acre Feet from full pool (75% full), so expect low flows for a while. The good news is Spinney Reservoir and Eleven Mile Reservoir are full, so incoming flows are now approaching 450 cfs. Pray for a good monsoon season to assist in filling Cheesman Reservoir. In the mean time, anglers can plan on tougher than normal fishing. Look for strong hatches of midges and sporadic BWO’s and caddis. Water temps have been in the mid 40’s during the morning, but rising quickly the mid 50’s mid afternoon. Please pinch your barbs and release the trout quickly. Keep them in water as much as possible and try to keep your photos (especially grip and grins) to a minimum until the flow improves…
