Brown, rainbow, Mackinaw, and brook trout and kokanee salmon attract anglers to the park's waters both in summer and in winter. The three dams of the Wayne M. Aspinall Unit dramatically changed the area's fishery. Where once the rainbow and brown trout of the Gunnison River fed predominantly on aquatic insects, some fish of Curecanti's lakes feed on plankton.

Plankton are microscopic plants and animals that flourish in this new lake environment. Brook trout favor the lake's tributary streams. The lakes' concentration of plankton is suitable for maintaining kokanee. Kokanee lure many people to the area and particularly during the snagging season, which generally begins in October. Rainbow trout are the most commonly caught fish. In Blue Mesa Lake's deep subsurface canyons lurk cold-water loving Mackinaw (lake) trout caught at more than 30 pounds here. Rainbows, introduced in the Gunnison River in the 1880s, are still stocked along with kokanee salmon. During the summer season you can learn more about the park's fish by joining a ranger for fish feeding at the Elk Creek Visitor Center's fish pond.

Troll at 5 mph for rainbow, slower for kokanee. Kokanee travel in schools. If you get a strike but don't pull in a fish, it may mean that you are trolling too fast for this tender-mouth salmon. Troll deeper for coldwater-loving Mackinaws. In summer, run leaded lines 40-70 feet deep.

Shore fishing is best when lake levels are low, in late spring and early summer. As the lake level rises and the water warms the fish are found deeper and in the middle of the lake.

Snagging for kokanees begins in October For exact date, call park headquarters.
