Gavins Point Dam, Embankment dam and hydroelectric station near Yankton, US
Gavins Point Dam is an embankment dam spanning the Missouri River between Nebraska and South Dakota, serving as a major water management structure. The facility controls river flow and creates a large reservoir that extends behind the structure.
The Army Corps of Engineers built the structure between 1952 and 1957 as part of a major program to manage and utilize the Missouri River basin. The project emerged from the need to control flooding and provide water for irrigation and power generation.
The Lewis and Clark Visitor Center at Gavins Point Dam provides educational programs about water management and energy production to over 890,000 visitors.
A visitor center on-site provides exhibits and information about water control and power generation. The surrounding area is suitable for activities like hiking and fishing along the lake.
The reservoir behind the structure is named after the Lewis and Clark expedition, honoring the historic explorers who traveled this river region. Over time, the lake has accumulated sediment, presenting ongoing management challenges for operators.
