Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation. Dams and their reservoirs provide recreation areas for fishing and boating. They help people by reducing or preventing floods.
Regarding this, what are the benefits of building a dam?
Dams pro vide a range of economic, environmental, and social benefits, including recreation, flood control, water supply, hydroelectric power, waste management, river navigation, and wildlife habitat. Dams provide prime recreational facilities throughout the United States.
What is good about a dam?
There are 84,000 dams in the U.S. that provide flood control, drinking water, agricultural irrigation, hydropower, and recreation. Dams are engineered structures—like roads, bridges, and railroads—that make our high quality of life possible. Hydropower is the largest source of renewable electricity in the U.S.
How do dams impact the environment?
The alteration of a river's flow and sediment transport downstream of a dam often causes the greatest sustained environmental impacts. Life in and around a river evolves and is conditioned on the timing and quantities of river flow. A dam also holds back sediments that would naturally replenish downstream ecosystems.
