What is the largest hydroelectric dam in the United States?
the Grand Coulee Dam

Does the UK have hydroelectric dams?
Generation by hydropower Today the UK has a total hydropower installed capacity of over 4,700 MW, including over 2,800 MW of pumped storage. The vast majority of installed capacity is located in the wet and mountainous regions of Wales and northwest Scotland.
