Description:

Threatened or endangered salmon and steelhead originating in the Snake River basin must pass through a series of eight major hydroelectric dams during their seaward migration. Understanding the effects of speci ﬁc dam passage routes on lifetime survival for these stocks is essential for successful management. Juvenile ﬁsh may pass these dams via three primary routes: (1) spillways, (2) turbines, or (3) juvenile bypass systems, which divert ﬁsh away from tur- bines and route them downstream. Bypass systems may expose ﬁsh to trauma, increased stress, or disease. However, numerous studies have indicated that direct survival through bypass systems is comparable to and often higher thanthat through spillways. Some researchers have suggested that the route of dam passage affects mortality in the estuaryor ocean, but this is complicated by studies ﬁnding that ﬁsh size affects the route of passage. We tested whether pas-
