Our 4% donations went toward the renovation of the fish ladder at Hiram M. Chittenden locks.
All fish, including endangered salmon, must pass through the locks, spillway or the fish ladder to move between Lake Washington and Puget Sound. In 1976, Corps of Engineers officials renovated and improved the ladder to reflect changes in fish conservation.
Today's ladder has 21 steps, or weirs, which allow the fish to swim upstream on a gradual incline. For many years the locks has been the focus of studies detailing migrating juvenile and adult salmon behavior. A cooperative effort among the U.S. Fish and Wildlife Service, Washington State Department of Fish and Wildlife, Muckleshoot Indian Tribe, City of Seattle, King County and Water Resource Inventory Area 8 and U.S. Army Corps of Engineers Seattle District, the studies have resulted in many fish passage improvements.
