Rock Island Dam, Hydroelectric power station on Columbia River, Washington
Description
Rock Island Dam is a hydroelectric power station spanning the Columbia River in Washington and generates electricity for the region. The facility contains two powerhouses with a combined 19 generators that together produce about 629 megawatts of power.
History
Construction began in 1930 during the Great Depression and finished in 1933, making it the first dam to cross the Columbia River. This marked a turning point in power supply for the Northwest and opened new possibilities for hydroelectric development in the region.
Culture
The dam's development transformed the regional power infrastructure and created employment opportunities for local communities during economic hardship periods.
Practical
The dam structure can be viewed from outside and offers views of the power generation facilities and river traffic. A visit is best during daylight hours when the structures are clearly visible.
Did you know?
The second powerhouse uses horizontal turbine generators that ranked among the world's largest when installed in 1979. This technical solution allowed power production to be significantly increased.
