White River Falls State Park, State park with waterfall in The Dalles, Oregon, US

White River Falls State Park is a state park in north central Oregon, 35 miles by road south of The Dalles and 4.5 miles east of Tygh Valley. Its focus is the falls where the White River drops 90 feet from a basalt shelf. At the base stand the ruins of a hydropower plant that supplied electricity from 1910 to 1960.

A hydroelectric power plant was built at the waterfall's base in 1910 to supply electricity to nearby counties for over 50 years. The facility was later abandoned, and its ruins remain visible at the site.

The falls sit at river mile 3 of the White River, which joins the Deschutes at river mile 46.5. The name comes from the river's pale, silt-laden water, and the park draws visitors who come to see the 90-foot drop and the plant ruins below it.

A steep trail leads from the parking area down into the canyon with several viewpoints along the way. Good footwear is important as the path can be slippery, especially after rain or snow.

The falls sit at river mile 3 of the White River, which joins the Deschutes at river mile 46.5. The park lies 4.5 miles east of Tygh Valley and 35 road miles south of The Dalles, in a valley at about 286 metres above sea level.
