List of the Advantages of Dams

1. Dams provide us with a source of clean energy.

Hydroelectricity is responsible for 19% of the world’s energy supply, offering over 3000 terawatts each year. We can produce power from dams because of the kinetic energy of the water movements as it causes turbines to spin. That’s what allows us to generate electricity that is clean and renewable. Once the dam gets entirely constructed, we no longer have a dependence on fossil fuels to be responsible for the energy we need to maintain a modern lifestyle.

The United States is one of the largest producers of hydroelectricity in the world today, even with the reduction of operational facilities. Americans generate over 103,000 megawatts of renewable electricity with this resource, with only Canada currently creating more power in this way.

2. Dams help us to retain our water supply.

When we take an opportunity to dam a river, then the water will pool to form a reservoir behind the structure. This outcome allows the population centers in that region to collect fresh water during periods of heavy precipitation for use during a dry spell or drought. We also use this engineering marvel to control floodwaters or to supply a fixed amount of fluid to the surrounding areas for agricultural irrigation.

3. This technology provides us with critical recreational opportunities.

Dams can provide us with a wide range of economic, environmental, and social benefits. Numerous reservoirs around the United States offer opportunities to go camping, boating, and waterskiing. It gives regions that generally wouldn’t have water access a place to have a boat launch that supports commercial fishing activities. These destinations can be the perfect place to have a picnic, go hiking, and spend time with your family.

4. A well-constructed dam provides several flood-control benefits.

Dams help to prevent property loss while reducing the risk to human life from annual flooding events. These structures can impound the floodwaters into the reservoir behind the dam, allowing us to release them under control or to store it for future use. We can divert excessive precipitation toward municipalities for fresh drinking water, create more irrigation opportunities, and meet a variety of energy-related needs.

The Nile River is famous for its unpredictable annual flow throughout history. As climate change continues to progress, the patterns of El Nino and La Nina in the Pacific Ocean will continue to increase. That means we will have more cycles of excessive precipitation and drought, and dams can help us to regulate this issue.

5. Dams give us a way to irrigate croplands that may not receive enough moisture.

About 10% of the croplands in the United States are currently irrigated using water that is stored in reservoirs behind a dam. Tens of thousands of jobs are directly tied to crop production and other agricultural activities that happen because of this benefit. Our food distribution networks remain active and consistent because of this advantage, and it allows us to do more with our growing efforts than if we relied on seasonal precipitation patterns alone.

6. A dam can provide a stable system of navigation.

We can use dams on rivers to provide a stable system of inland water transportation. The navigable waterways of the United States, like those found on the Mississippi River, can be challenging for some boats to use because of varying water levels. Installing a system of locks with this technology creates a safe place for us to transport goods and a variety of additional benefits.

7. Reservoirs can serve as a source of drinking water.

Because the water stored behind a dam in a reservoir is fresh, we can use it as a source of drinking water for nearby towns and cities. It is not unusual for communities in the United States to obtain their entire supply from streams or rivers that are close. We can use large canals, pipes, and other methods of transportation to ensure that every home has access to safe and clean drinking water.
