The Wenatchi tribe was far more isolated prior to the arrival of the horse, but afterward they adopted many of the traditions and style of dress of the Plains Indians and were closely allied with the Spokane tribes by the time white settlers arrived. It is also estimated that 90% of the indigenous population died prior to white contact, infectious diseases spreading with the horse far in advance. The Wenatchis were not given reservation land by the federal government—though they had actually signed a treaty, it was never recognized, and fell by the wayside as new settlers moved into their territory. The Wenatchi Indians unlike many other tribes did not engage in war with the new arrivals and were even friends with the first white settlers and their families. Janie Hollingsworth, an early settler born in 1911, remembers fondly growing up with the daughter of the Wenatchi Chief in the Nahahum Canyon area, riding horses together happily until the government decided to round up all the Indians and put them in existing reservations. Subsequently, most modern day Wenatchis are found living on the Colville Indian Reservation, with a small number living on the Yakama Reservation.
Wenatchapam Fishery
The Wenatchapam Fishery is an important cultural site for the Wenatchi people. The land is currently incorporated into Wenatchee National Forest at the confluence of the Wenatchee River and Icicle Creek near Leavenworth. The fishery was named as a reservation site in the Yakama treaty from the Walla Walla Council, and the boundaries were surveyed and designated by Army personnel in subsequent years. Following the establishment and reallocation of lands of the Colville Indian Reservation, Wenatchi Chief John Harmelt was supported by Chief Joseph of the Nez Perce people in lobbying for federal protection of Wenatchi rights to the fishery. More white settlers moved to the area, infringing on the Wenatchi's claim to the land, and the Great Northern Railway was approved to build a route through the reserved land. Another survey was commissioned in 1893, but federal agent L.T. Erwin, who was aligned with the settlers and railroad company, intervened in the process. He attempted to offer Chief Harmelt individual allotments in the mountains to the remaining Wenatchi people, however Harmelt insisted on consulting with his people before entering into a decision. In his absence, Erwin told the Yakama tribal leaders that the Wenatchi had sold their land rights, and the Yakama sold their share for $20,000.
