Famous Dams In The USA; Incredible US Dam Architecture 

Dams are a common part of human architecture, and we have built them for thousands of years. Dams are an effective way of controlling water. 

This can be crucial to preventing floods or creating reservoirs for irrigation. There is a wide diversity in size and function based on location.

With the invention of electricity came hydroelectric power. This idea allowed humans to tap electricity from water using dams. 

Most of the recent dams are primarily hydroelectric, and they have turbines within them. Let us take a look at some of the famous ones in the US;

1. Oroville Dam
