In the old Willapa Fall chinook fishery it was thought that the fish were mostly Willapa origin. It was later found to be GH & Columbia fish were present in substantial numbers. I imagine Springers from streams farther down the coast dip in and caution dictates you manage that way with C&R to reduce any wild impacts on the southern bound fish. My two bits.
