2. Although Pacific Rivers Council et al. (1993) also included populations from Idaho in their petition, all native populations of coho salmon from Idaho are believed to be extinct.

3. Pacific Rivers Council et al. (1993, p.11) cite this document as ODFW 1992.

4. Citations followed by "App." are given in Appendix C.

5. River entry was taken from reports which specifically listed it, or was based on the timing of peak in-river catches of coho salmon.

6. Spawn timing was compiled from reports listing spawn timing, or based on an average of the dates when peaks in spawning occurred, as reported in spawning ground surveys.

7. The data presented come from measurements of naturally spawning coho salmon and fish landed in in-river fisheries. This latter source of data is included because of the scarcity of direct data for naturally spawning populations.

8. The Butte Falls Hatchery is located on the Rogue River (in the southern Oregon/northern California coasts ESU) but raises Umpqua River coho salmon and releases them into the Umpqua River (in the Oregon coast ESU). Because of the fish used and release location, we consider this hatchery under the Oregon coast ESU.
