South Platte River below Cheesman Reservoir Professional Review and Guide
"This 5-mile stretch of the South Platte River, between Cheesman Reservoir and the town of Deckers, is a series of crystalline riffles, runs, and pools winding its way through a deep granite canyon before opening up into a valley below Deckers.
Big browns up to 24 inches numerically dominate this section of river, but anglers catch mostly rainbows, from 14 to 28 inches. The key to success is to make the 20- to 30-minute hike into the canyon early enough to get one of the good holes. By the time the sun hits the water and swarms of anglers show up, the best fishing is usually over. Mayflies and midges, with a healthy smattering of mysis shrimp and small fish, make up the prey base for these fish. When a hatch is on, the fish gorge themselves. When it’s over, often so is the fishing opportunity.
Key Species: Rainbow trout, brown trout."
