List of tallest dams in the United States facts for kids
Dams are huge walls built across rivers to hold back water. They create large lakes called reservoirs. These reservoirs are super important! They store water for drinking, help farmers water their crops, and can even generate electricity for our homes. Dams also help control floods, protecting towns and cities downstream.
This article lists the tallest dams in the United States. We'll look at dams that are over 300 feet (about 91 meters) tall. The height mentioned is from the very bottom of the dam to its top, not how deep the water is. We won't include things like levees (which are like long walls to stop floods) or dams made from mining waste. Even dams that are no longer used, like the Teton Dam, are included.
Most of the tallest dams in the U.S. are found in the western part of the country. This is because the land there has more mountains and deep valleys, which are perfect for building tall dams. The very tallest dam in the U.S. is Oroville Dam in northern California. It's a massive embankment dam (a dam made of earth and rock) that stands at 770.5 feet (235 meters) tall! It was finished in 1968. In fact, five of the ten tallest dams in the U.S. are in California. Big rivers like the Colorado River, Columbia River, and Sacramento River–San Joaquin River systems have many of these tall dams.
In the eastern U.S., tall dams are less common because the land is flatter. The tallest dam in the eastern U.S. is Fontana Dam in North Carolina. It's 480 feet (146 meters) tall and ranks 20th among all U.S. dams.
