Large numbers of adult tule fall Chinook salmon are returning to the Spring Creek National Fish Hatchery in Underwood.

Come in to the hatchery to view adults leaping up the fish ladder and take a closer look at them in the adult holding ponds. Spawning begins Sept. 15 and will continue through Sept. 30. Best times to view are in the morning, as the process often wraps up by 2 p.m. daily.
