The benefits are only that the regulated water in reservoirs can help in irrigation, water supply and water for industrial purposes. Dams’ impacts on ecosystems are mostly negative.

Are dams good or bad for the environment?

They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.

Is it good to build a dam?

What are the negatives of dams?
