Final answer:
Lake Franklin D. Roosevelt is the largest lake in Washington State, and it was created by the Grand Coulee Dam, which is the largest electric power-producing facility in the U.S. Located on the Columbia River, the Grand Coulee Dam is capable of producing 6.8 GW, overshadowing the 2 GW production of the Hoover Dam.
Step-by-step explanation:
Lake Franklin D. Roosevelt and Key Hydroelectric Facilities
Lake Franklin D. Roosevelt is the largest lake in Washington State, created by the impoundment of the Columbia River by Grand Coulee Dam. Grand Coulee Dam is not only the largest electric power-producing facility in the United States but also one of the largest concrete structures in the country.
Besides Lake Franklin D. Roosevelt, Washington State also boasts other notable bodies of water such as Lake Chelan, Ross Lake, and Lake Washington.
Although the Hoover Dam is a significant hydroelectric power source generating over 2 GW and was the largest of its kind when constructed, it is overshadowed by Grand Coulee's capacity of 6.8 GW. Furthermore, the Three Gorges Dam in China holds the title of the largest hydroelectric facility in the world.
It's important to note that while the Hoover Dam generates a significant amount of energy, the actual hydroelectric power production potential is determined by factors such as water flow and height from which the water falls.
Additionally, the Colorado River system, including the Hoover Dam's contribution to the large reservoir Lake Mead, showcases the importance of these massive structures in regulated water supply and hydroelectric power generation.
