Cache La Poudre River, CO

The Cache la Poudre River, (sometimes called the Poudre River, or the Poudre for short) is in the state of Colorado in the United States.

Its headwaters are in the Front Range in Larimer County, in the northern part of Rocky Mountain National Park. The river descends eastward in the mountains through the Roosevelt National Forest in Poudre Canyon. It emerges from the foothills north of the city of Fort Collins.

It flows eastward across the plains, passing north of the city of Greeley, and flows into the South Platte River approximately five miles east of Greeley.

From its headwaters downstream, through the city of Fort Collins, the Cache la Poudre River contains abundant populations of self-sustaining wild trout, with none of these salomnid populations being native to the river. The vast majority of trout that live within the river system are Brown Trout. The community of Fort Collins contains devoted Poudre River Anglers, who seek brown trout of all size, ranging from juvenile trout all the way up to piscivorous and predominantly nocturnal five to eight pound trout. Anglers pursue these trout most actively in the guise of a fly fisher and dozens, if not hundreds, of local fly patterns have been developed purely for use on the Poudre.
