The offspring of spring chinook salmon planted in 2000 have returned to the Walla Walla River as 10-15-pound four-year-old adults.
The returns are the result of the supplementation and habitat improvement program of the Confederated Tribes of the Umatilla Indian Reservation and the cooperative efforts of the Tribes, states and the Walla Walla Watershed Council, landowners, local irrigators and others.
