About Tuolumne River
Fly Fishing in the Upper Tuolumne River
The Tuolumne River is one of two major rivers that originate and flow from Yosemite National Park; the other being the Merced River. Flowing from the high Sierra Nevada, the Tuolumne eventually joins the San Joaquin River in the Central Valley.
Human habitation along the Tuolumne River is believed to have begun around 3000-7000 B.C. The Plains and Sierra Miwok were the largest local Native American tribes in the area prior to European contact. The first recorded use of the name “Tuolumne” was from the Spanish explorer Gabriel Moraga in 1806, and it is believed that he used the name of a local Native American village to refer to the river.
The River begins at the confluence of Dana Fork, which drains at Dana Mountain, and Lyell Fork, which drains from Mount Lyell. These forks join in the Tuolumne Meadows inside Yosemite National Park.
From the Meadows, the River receives two tributaries, Cold Creek and Conness Creek, and flows over two waterfalls, La Conte and Waterwheel Falls. The Tuolumne then flows through Glen Aulin Valley and then into a canyon. This area is particularly popular with white water rafters, as there is Class IV whitewater in this section.
After passing through the canyon, the River enters Hetch Hetchy Valley and the Reservoir, where it is joined by Falls Creek, Tiltill Creek, and Rancheria Creek. This is the end of the Upper section of the River.
Many years ago, the Tuolumne River contained teeming populations of chinook salmon and steelhead trout (at least in the lower reaches). Nowadays, you are more likely to find rainbow, brown, and brook trout.

Best Places to Fish the Upper Tuolumne River
Access to the upper section of the River ranges from easy to difficult. The area that provides the easiest access for fly fishing on this part of the River is the meadow section inside Yosemite National Park. Despite being one of the most visited areas of the Park the fishing is quite good since very few visitors are there to fish!
Outside the meadows, most of the upper Tuolumne is only accessible by foot via the John Muir Trail and Pacific Crest Trail. You can also find good fishing opportunities on the Dana and Lyell Forks.
Best Time to Fish the Upper Tuolumne River
The season for trout fishing on the Upper Tuolumne River is from the last Saturday of April through November 15. The best time to visit is in the summer, after the run off ends. It can be very difficult to fish the River in the spring, particularly during dry years. You can also find success fishing in the early fall.
Fly Box – What You’ll Need
The wild trout in Upper Tuolumne are not too picky when it comes to flies since they have a relatively short window to feed on the aquatic insects that hatch in the summer. Hatches are typical of Sierra West Slope freestone streams and include a variety of mayflies, caddis and stoneflies. Terrestrial fly patterns imitating ants, beetles and hoppers are also very effective.
Here is list of general fly pattern recommendations for the Upper Tuolumne River:
- Midge (#16-26)
- Western March Brown (#12-14)
- Little Olive (#16-20)
- Elk Hair Caddis (#12-18)
- Slate Gray Dun (#12-14)
- Pale Morning Dun (#14-18)
- Small Western Drake (#14-16)
- Spotted Sedge (#14-16)
- Parachute Adams (#14-16)
- Royal Wulff (#14-16)
- Renegade (#14-16)
Gear Recommendations
A 9-foot 4-wt fly rod with floating line is perfect for fishing dry flies and small nymphs on the Upper Tuolumne River. A tapered 9-foot leader, with tippet size 3X to 5X to match the flies you are throwing, is pretty standard.
