The 2016 San Diego Lake Protection Month started with an introduction of the various lakes of the county, particularly those who were utilized as reservoir lakes. The reason for this is that what is typically known as San Diego lakes are reservoirs that make up the city’s water supply system. San Diego has been known for the use of their lakes as a source of clean water, and the public is allowed access to these reservoirs for family outdoor activities such as family picnics, boating, and fishing.

The definition, description, benefits, and pros and cons of reservoirs were also discussed, some of which we will also briefly tackle here.

What Are Reservoirs?

Reservoirs are artificial or man-made lakes. They are vital water sources and can be found in many countries worldwide. They are created by constructing a dam around a river or by diverting a portion of the flowing river and keeping the water in the reservoir. When the dam is done, the river stagnates within the dam and is filled. Reservoirs are much larger than the natural lakes. These reservoirs are important in storing water for drinking, irrigation, or producing energy.

Advantages of Reservoirs

  • Easy and convenient access to water
  • Stronger protection of the downstream water from floods and other calamities
  • Production of hydropower (energy)
  • Storage of water for safekeeping in times of scarcity
  • Can be used as drinking water and other water resources
  • Can be used as a source of irrigation

Disadvantages of Reservoirs

  • Building and maintenance of dams are expensive
  • When more people move to the area close to the reservoir, there will be more use of the water, which may lead to social, economic and health issues
  • Reservoirs may often flood or overflow, which may cause the local population to flee and lose their homes, etc.

Contamination of reservoirs has to be avoided through wastewater treatment and the use of buffer zones. Water purification procedures must also be followed if these reservoirs are to be used as drinking water.
