Tueeulala Falls - California Waterfalls; Yosemite Natl. Park, Hetch Hetchy Reservoir-hike/trail/map/directions

Tueeulala Falls and Wapama Falls flow into Hetch Hetchy Reservoir, which was created to provide water to San Francisco. O'Shaughnessy Dam was built in 1914, one of the greatest travesties ever to occur in America. Before it was built, Hetch Hetchy Valley was as beautiful and awe-inspiring as Yosemite Valley. Now it is destroyed.

Nonetheless, the reservoir area is still pretty, and the waterfalls here are definitely worth visiting in the spring. It is an easy and pretty hike along the reservoir to get to them. You will reach Tueeulala Falls about 1.7 miles along the trail, where it drops 800 ft. off a high cliff in the spring. I have seen the waterfall listed at 1000 ft. high, but it is closer to 800 ft., maybe slightly higher. Before the dam was built, Tueeulala Falls would have been taller, probably around 1200 ft.

Note that Tueeulala Falls is actually further to the east than how it is marked on the USGS Topo maps (closer to Wapama Falls). In fact Tueeualala Falls is actually runoff from Falls Creek, which splits at high volume above Wapama Falls. The other waterfall marked is Hetch Hetchy Falls. Even with the split of Falls Creek, Tueeulala has more volume than the marked waterfall.
