Lake Washington Ship Canal Fish Ladder pamphlet - life cycle chart

Life cycle chart (of anadromous fish that come through the Lake Washington Ship Canal Fish Ladder). From a pamphlet about the fish ladder, which is located across the channel from the Hiram Chittenden Locks, Seattle, Washington. Scanned at 600 dpi and slightly cleaned up.
The diagram covers both natural propagation and hatchery propagation. In the pamphlet, a remark to the lower right of the diagram says, "Length of the life cycle and of hatchery care vary with species and conditions."
