its comes from lake mead and they clean the water
Hoover and Aswan are both great dams.
Hydroelectric dams.
Well man made dams like the Hoover dam can support the water from overflowing while beaver dams a just basically homes.
Dams have turbines that turn with the water and create electricity.
water mill
Water (hydro electricity from dams).
The purpose of the dams that are found in the state of PA are to prevent water from entering another water source or landform. Dams are often manmade, but can be constructed by animals like beavers.
Dams such as Hoover Dam or the dams of the Niagra River generate hydroelectric power.

Well, think about it, some dams make energy by the water running through it, like the Hoover Dam.
Dams are put in place to hold back water. This is generally used to create a water reservoir, but can also sometimes be used as a form of flood control. Hydroelectric dams, like the Hoover Dam, hold back water to create water pressure, to push turbines that generate electricity. In the case of the Hoover Dam, which holds 9.2 trillion gallons of water, extremely massive amounts of water pressure are obtained, and the 17 turbines combined make 2.8GW of power, which is about as much as 3 nuclear power plants.
