Restore Similkameen Presentation - May-u

 From its headwaters in British Columbia’s Manning Provincial Park, the Similkameen River flows 122 miles to its confluence with the Okanogan River near Oroville, Washington. Significant tributaries to the Similkameen include Canada’s Tulameen, Pasayten and Ashnola Rivers, which originate in Washington state’s Pasayten Wilderness. The Similkameen River watershed encompasses over 3,579 square miles.

In addition to scenic beauty, the Similkameen provides important water resources, critical habitat, and extensive recreational opportunities in both the U.S. and Canada. It also is of deep cultural significance to the tribes of the watershed. 


pre-dam era

"Rock Wall" was the Indian name for the Squantl (Similkameen) Falls. The name Squantl Falls was recorded for the first time by Smith & Calkins in their U.S. Geological Survey Report entitled "A Geological Reconnaissance Across the Cascade Range (1904)." The local name for the falls before the building of the dams was Similkameen Falls.


Being about 33 feet high and fairly perpendicular, the falls created a barrier beyond which anadromous fish appear never to have migrated. Susan Cohen (LeMay 1979), an Indian woman, states that "there has never been any salmon in the Similkameen north of the Rock Wall."


Cohen explained that her ancestors would gather at the base of the Rock Wall to catch the salmon as they made their annual run up the Okanogan River and into the lower part of the Similkameen, but only to the base of the falls. Indian legend has it that animals built the Rock Wall so as to trap the fish, thereby providing the wild animals with a source of food. *HISTORIC AMERICAN ENGINEERING RECORD
