Cheesman Canyon is the most technical stretch of the South Platte River near Denver, especially in winter. Low clear water, heavily pressured trout, and steep canyon walls create a fishery that rewards patience and precision.
Fishing
Fishing in Cheesman is improving, but it’s still one of the most technical sections on the South Platte. Flows remain controlled, but upstream changes across the system are starting to influence consistency.
There is a real midday window now, with more fish feeding than a couple weeks ago, but nothing about this stretch is forgiving. If your drifts aren’t clean or your depth is off, you’ll see fish and not touch them.
