The ideal place for a hydroelectric dam is what's called a slot or "gunsight" canyon. Narrow and high, to create the best conditions with the smallest dam. Dams in wide, relatively flat places like along the Columbia River exist, but they are multi-purpose, built for flood control, irrigation, navigation (with channels and locks), and recreation benefits in addition to hydroelectric. |
