Grape Creek below DeWeese carries a trout fishery into a rugged canyon
Below DeWeese Reservoir, the water becomes Grape Creek and heads off into steep, rocky canyon country. Colorado Parks and Wildlife describes this stretch as a strong fishery, holding good numbers and sizes of both brown trout and rainbow trout.
This is backcountry water, not a roadside pond. Getting to much of Grape Creek means walking into remote, rugged ground, including reaches near state trust land and, farther downstream, the Temple Canyon area toward CaƱon City. The reward is a quiet creek with wildlife around; the trade-off is effort, distance, and rough footing.
One thing that matters everywhere in Colorado: fishing rules can change by the specific stretch of water. Bag limits, size limits, and whether bait or only artificial flies and lures are allowed can differ from one reach to the next, and special rules sometimes apply just below a reservoir. The land you cross to reach the creek can also have its own access rules. A general fishing license does not answer all of those questions by itself.
So before you fish Grape Creek, check the current regulations for that water and the access rules for the land you will cross with Colorado Parks and Wildlife.
