Scarcity of drinking water is one of the major problems in the sun-city Jodhpur, Many lakes situated in the outskirts of Jodhpur have been serving water to this city for several years. But the existence of these ancient reservoirs is being endangered due to unplanned and injudicious sandstone quarrying within their catchment area. The quarrying activities are continuously changing the land-profile. Hence, the direction of slope of the catchments area of these reservoirs is also being disturbed by large mined out pits and waste dumps. A huge amount of rainwater gets logged in these giant pits instead of feeding the reservoirs named Balsamand, kayalana, kaliberi, etc. As a result of this, these water reservoirs dry up after every two to three years. Day by day severity of this problem is increasing due to increase in quarrying activities in the catchments area. The type of topography that has resulted after quarrying leads to the process of devegetation. This phenomenon increases the hot plate effect in the eco-system leading to the hydrological imbalance. Therefore, it is essential to study how the water resources of the area can be protected if not improved by doing the planned quarrying operation. This paper highlights a case study conducted in the catchment area of Balsamand lake, which is 11km far from Jodhpur city. The objective of the study was to determine the extent of impact of mining activities on natural drainage system, so that suitable measures may be taken within time to restore the natural drainage pattern of the lake. Further recommendations are given to restore the natural drainage system and reduce the water logging in pits.
