Why are picnic spots often developed around or near lakes?

  1. Flood Control: Dams help regulate water flow and reduce the risk of floods by storing excess water during periods of heavy rainfall or snowmelt, and releasing it gradually.
  2. Irrigation: Dams provide a reliable source of water for irrigation, which is essential for agriculture, particularly in arid and semi-arid regions.

  3. Hydroelectric Power Generation: Dams can generate electricity through hydroelectric power plants, which use the force of falling water to turn turbines and produce electricity.

  4. Water Supply: Dams can provide a reliable source of water for drinking, household use, and industrial use.

  5. Recreation: Dams can provide opportunities for recreational activities such as swimming, boating, and fishing, which can contribute to local economies.

  6. Environmental Management: Dams can help regulate water temperature and flow, which can benefit aquatic ecosystems and support biodiversity.

  7. Navigation: Dams can create deep water channels that allow for navigation of ships and boats, which can facilitate trade and transportation.
