List of Dams in Botswana
What is Dams?
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability.

Frequently Asked Questions
Which is the biggest dam in Botswana?
Dikgatlhong Dam, which is the largest dam in Botswana with a water holding capacity of 400 million cubic metres, is full to capacity and overflowing.
What is dam and its benefits?
Dams and reservoirs are constructed to store surplus waters during wet periods, which can be used for irrigating arid lands. One of the major benefits of dams and reservoirs is that water flows can be regulated as per agricultural requirements of the various regions over the year
Why are dams used?
People build dams to control water—to make sure the right amount is at the right place at the right time. River water rises behind dams, forming artificial lakes called reservoirs. The stored water can be used to generate electricity or to supply water for homes and industries, for irrigation or for navigation.
Why dams are called?
Dams are called multi-purpose projects because:1 Earlier they were built to impound rivers and rainwater could be used later for irrigation. 2 Now dams are built not only for irrigation but for generation of electricity water supply for domestic use flood control recreation inland navigation and fish-breeding.
How do dams work?
A conventional dam holds water in a man-made lake, or reservoir, behind it. When water is released through the dam, it spins a turbine connected to a generator that produces electricity. The water returns to the river on the downstream side of the dam.
Why are dams good for the environment?
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. 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.

How dams are built?
A dam is built to control water through placement of a blockage of earth, rock and/or concrete across a stream or river. Dams are usually constructed to store water in a reservoir, which is then used for a variety of applications such as irrigation and municipal water supplies. Q.
Who invented dams?
As early as 400 BCE, Asians built earthen embankments dams to store water for the cities of Ceylon, or modern-day Sri Lanka. In the 5th century AD, the Sinhalese built several dams to form reservoirs to catch the monsoon rains for their intricate irrigation system, and many of these reservoirs are still in use today.
How do dams work water?
The construction of a dam across a river forms a reservoir that raises the water level upstream, stores the water, and slows down its rate of flow. This improves the navigation conditions upstream of the dam for ships and boats.
