File:Lake Washington Ship Canal Fish Ladder Pamphlet - The Fish Ladder In Profile.jpg
Summary
Description |
From a pamphlet about the Lake Washington Ship Canal Fish Ladder at the Hiram M. Chittenden Locks, Seattle, Washington. Diagram of the fish ladder in profile. The actual fish ladder makes several right angle turns, which are not reflected in this diagram. Caption from the pamphlet: This shows the the height of each weir. Most weirs are one foot higher than the previous one. The last three weirs are adjustable to the level of Salmon Bay. Salt water is mixed with fresh water by the diffuser well in weirs indicated by dark blue [dark gray in scan]. The longest weir in the ladder was created when the fish viewing window was built for your viewing pleasure. Scanned at 600 dpi (grayscale) and cleaned up. |
