History of steelhead fishing on the Nez Perce Reservation in the Orofino area

I am interested in the history of steelhead fishing on the Nez Perce Reservation in the Orofino area. I understand it was closed to sport fishing in the late 70’s or early 80’s then opened back up. Does Idaho F&G have that info or can you point me in the right direction? Maybe a person or a book? Thank you for any help you can offer!
