Some johads also have bricked or stones masonry and cemented ghat (series of steps and / or ramp). Johads also cater to resident and seasonal migrant birds as well as wildlife from the nearby bani (forest). State fisheries departments also promote the use of these johads for raising fishes on contract basis for commercial purpose . Johads are often seen surrounded by embankment, with water well and trees around them . In many parts of the state, the annual rainfall is very low (between 450 and 600 mm) and the water can be unpleasant to drink . Rainfall during July and August is stored in johads and used throughout the year . Johad in Haryanvi language and Rajasthani language are also called sarovar, taal and talab in Hindi language, and water pond or lake in English . Johads are called as khadin in Jaisalmer district . Smaller cemented water tanks called tanki or tanka in parts of Rajasthan are also sometimes mistakenly referred to as johad . Over 4,500 working johads in Alwar district and surrounding districts Rajasthan were revived by the NGO Tarun Bharat Sangh by Rajendra Singh . Haryana formed the Haryana State Waterbody Management Board to rejuvenate and manage 14,000 ponds in the state, including the development of 60 lakes in Delhi NCR falling within the state . </P> <P> Johads can be of several types, such as dug out in areas to which rainwater can be easily channeled . Alternatively, simple mud and rubble barrier check dams may be built across the contour of a slope with a high embankment on the three sides while the fourth side is left open for the rainwater to enter . These catch and conserve rainwater, leading to improved percolation and groundwater recharge . They are very common in most villages of states of Haryana, Rajasthan, Uttar Pradesh and the Thar desert of Rajasthan in India . </P>
