Within Yosemite National Park you’re most likely to catch rainbow, brook, and brown trout. Crappie, sunfish, and black bass are also common in some of the warmer lakes surrounding the park. Native fish are only found in the lower elevations of Yosemite National Park from lower Merced River up to El Portal.
Anglers hook excellent rainbow and brown trout on the Tuolomne River, especially on the stretch above Hetch Hetchy. Fishing tends to be better at lower elevations. The only restriction for keeping fish is for wild rainbow trout on the Merced in the Valley proper; that stretch is catch-and-release only.
Visitors have recommended Tenaya Lake for its fall action as well as the Hetchy Hetchy reservoir, both reachable by car. Tenaya is located off Tioga Road and, at 150 acres, is one of the three largest lakes in the park. Rangers tell visitors that the catch can be even better outside the park in Inyo National Forest, where the Forest Service actively stocks trout.
