Water is the basic necessity for all forms of life, human beings, other animals as well as plants. Some parts of our country have good resources of water whereas other parts suffer from chronic water shortage. The regions having good availability of water are flourishing because they have good crops but the regions having shortage of water are in the thick of poverty because of poor crop growth.
It is, therefore, necessary to have proper management of available water resources so that there is an equitable distribution of water for all the people in all the parts of the country. The various sources of water which are available to us are: Rains, Rivers, Lakes, Ponds.
Rain is a very important source of water. Rains in India are largely due to monsoon which lasts for a few months. This means that most of the rainwater falls on the earth in a few months of the year. This rainwater fills the lakes and ponds, and also flows into rivers.
Some rainwater also seeps into the ground and becomes available as ground water (or rather underground water). Though most of the parts of our country get a good rainfall during monsoon but due to the loss of vegetation cover, much water does not seep into the ground, it rather flows into rivers.
Rainwater is stored in lakes for use over a long period of time. There are some natural lakes in our country. Some artificial lakes have also been made at various places to store rainwater to meet the increasing demand for water. In fact, many cities of our country depend on such lakes for their water supply during the year.
