Abstract
The Wanapum Dam is located
in the State of Washington on
the Columbia River, approximately
four miles downstream
of I-90 and the town of Vantage
(Figure 1). The layout for the project
is shown in Figure 2. Completed
in 1964, the Wanapum development
consists of an earthen embankment
on the left abutment, a
left gravity section with fi sh facilities,
a powerhouse with 10 generation
units, six future unit intakes,
12 spillway monoliths with
large radial gates, a right gravity
section with fi sh facilities, and
another earthen embankment on
the right abutment.
