Fishing was popular with early settlers in the Rocky Mountains. In an attempt to improve the sport, they stocked many streams with non-native species of trout and moved trout to lakes and streams that lacked them. The only trout native to the park were the greenback cutthroat and the Colorado River cutthroat.

The National Park Service stocked non-native Yellowstone cutthroat trout as late as 1968. These trends to "popularize" National Park areas have been reconsidered. Removing exotic or non-native fish and restocking with native greenback cutthroat and Colorado River cutthroat trout are returning park waters to their original condition.

Populations of at least four species of trout exist in the park—brown brook, rainbow, and cutthroat. Some suckers also inhabit the streams and lakes. Only 42 of the 156 lakes in the park have reproducing populations of fish. Cold water temperatures and lack of spawning habitat prevent reproduction in other high altitude lakes. Supplemental stocking is done only to restore native species to altered waters. Successful fishing at high altitudes is spotty, even from waters known to contain fish. The possession limit has been held to a minimum, resulting in an increasing population of cutthroat, brown, and rainbow trout. These fish are maturing and spawning successfully.

The Cache la Poudre River originates in the park, and while it's not fishable within park boundaries, it's definitely a worthy destination if you're in the area.

Fly fisherman may want to check out the Big Thompson River, The Fall River, and the Roaring River in the northeast corner of the park.

Today, fishing activities are balanced with efforts to restore and perpetuate natural aquatic environments and life. Here are some lakes and creeks open to fishing, including some with special catch-and-release regulations. There are also some closed waters you need to steer clear of. Before you wade in, check with the Park Service for license requirements, size and possession limits, and other regulations.
