	note = {For eons, a waterfall on the Siletz River effectively separated the summer and winter steelhead runs, allowing each group of steelhead trout to evolve for maximum fitness in different environmental conditions.  Then, in the early 1950s a fish ladder was constructed, which allowed for the two groups to hybridize. The ladder was maintained until 1994.  The resulting progeny would be more genetically diverse, but might not be the most fit to succeed in their environment.  This article examines the extent of hybridization in the summer and winter steelhead runs on the Siletz, as well as their interactions with hatchery populations. {\textquotedblleft}These trends suggest that the risks of outbreeding and inbreeding depression need to be carefully balanced to successfully manage this and other similar populations{\textquotedblright} (p.1384).},
