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 the flows to drop dramatically as Denver Water prepares to ramp up flows on the North Fork. Anglers should prepare for hatches of golden stoneflies, PMD’s, and blue-winged olives.
Tips and Other Information: Look for flows to drop as Denver Water prepares to move water from Dillon Reservoir via the Roberts Tunnel. Cheesman Reservoir is down to 95% of capacity which is alarming after a huge snow pack. To the contrary, Dillon is at 101% capacity, so Denver Water will service their customers on the Front Range and outlying areas with water from Summit County. Anglers should prepare themselves for hatches of midges, caddis, blue-winged olives, PMD’s, and golden stones. Amy’s Ant continues to produce some great fish on top, and a dry and dropper rig is never a bad idea, especially in the skinny water. Water temps are a concern as they are in the upper 50’s to mid 60’s. Keep and eye on them as the volume is reduced, the temps will rise.
