Dam Purposes: Water Supply, Flood Control, Hydropower, Navigation, Recreation, and Habitat

Dams are multipurpose infrastructure projects. Primary functions include:

• Water Supply: Storage for drinking, irrigation, industry.
• Flood Control: Attenuate peak flows, reduce downstream damage.
• Hydropower: Generate electricity via turbines.
• Navigation: Create reservoirs/locks for inland shipping.
• Recreation: Boating, fishing, swimming, tourism.
• Fish & Wildlife Habitat: Reservoirs and regulated flows can support ecosystems.

Modern dam design seeks to balance these benefits with environmental and social impacts.
