| Abstract | Long Description |
A morphometric survey of Lake Chelan was conducted in July 1986. Forty echosounding profiles of subsurface topography were used to prepare three bathymetric maps of varying detail. Lake Chelan is the largest natural lake in Washington and the third deepest lake in the United States. Maximum and mean lake depths are 1,486 feet (453 meters) and 474 feet (144 meters), respectively. Lake volume is approximately 25 billion cubic yards (19 billion cubic meters) and hydraulic retention time is 10.6 years. Much of the lake is U-shaped in cross-section, a feature characteristic of glaciated valleys. The hydrographic attributes of Lake Chelan are strongly influenced by the morphometry and bathymetry of Lucerne Basin, which accounts for 74 percent of the lake′s surface area and 92 percent of its volume. |
