Lower Crystal Creek Falls (ADA accessible) is the only “man-made” waterfall in the park. When the Central Valley Project was designed in the 1920s, an important component was the diversion of a large portion of the Trinity River to Whiskeytown Lake and from there to the Sacramento River. A 17-mile tunnel was excavated to transport the water underground from Trinity Dam to Carr Powerhouse and the tailings were dumped in the area near Crystal Creek Falls.
When it is necessary to shut down Carr Powerhouse for maintenance or to enter the tunnel for cleaning, the valve is turned and the excess water from the tunnel spills into Crystal Creek.
When the overflow structure was built, the Bureau of Reclamation rerouted Crystal Creek. The creek was moved about 50 feet to the left to make a shortcut over the cliff, creating this picturesque waterfall.
Leashed dogs allowed on trails. Over the years, dogs that have run freely off the trails have encountered mountain lions as well as suffered severe bouts of poison oak, notably on their noses and underbelly. Of course, this can then spread to us human types.
