Seen here is a mountain dam on a river near Estes Park, Colorado. In the United State there are approximately 75 000 dams ranging from massive arch dams like the Hoover Dam or Glen Canyon Dam to small mass acting dams like this one. However, most dams in the United States aren’t hydroelectric dams, meaning they make electricity by passing water through turbines, like the large famous dams everybody knows about. Perhaps as demand for electricity increases these smaller dams will be retrofitted to capture the energy that is present in their reservoirs.
