(Hetch Hetchy – O’Shaughnessy Dam Overflow) – Year of Yosemite (YOY) – Day 187

O’Shaughnessy Dam Overflow

Water release at the Hetch Hetch reservoir

We followed the weather forecast for a couple of weeks prior to our visit to Yosemite so we understood that there had been much precipitaton. We were glad because we wanted the waterfalls to be at their full-flowing best.

With such abundance of water, the O’Shaughnessy Dam seemed to be very full and they were releasing water to maintain the “balance” of the reservoir. As you will note, there is a large, forceful stream of water being released. More rain was anticipated on this hiking day as well so this photograph represents the sunniest time we had at Hetch Hetchy.

Also notice the curved railing and walkway atop the dam. At the very left of the railing and walkway is the entrance to the tunnel passageway.

Hetch Hetchy Reservoir

Hetch Hetchy Reservoir

Walking from the parking area near the main hiking trails, hikers will soon see the entrance to the pathway and the O’Shaughnessy Dam which corrals the Tuolumne River to create the reservoir. According to Wikipedia, Hetch Hetchy provides water for more than two million people in the San Francisco area.

The creation of the Hetch Hetchy reservoir was controversial and there is a movement today to try to restore it to its original splendor. You can find out more about this effort by visiting Restore Hetch Hetchy. They have a photograph of the beautiful Hetch Hetchy Valley before it was flooded.
