Ground water level fluctuation space to space (Spatial) and time to time (Temporal) is a major problem in India and the assessment of spatiotemporal characteristics water level fluctuation trend is very important in the point of view of future development. Water level fluctuation in Jaipur city is a major problem. Water level data is collected by field survey & PHE department and population data from census of India. Analysis of population data shows that city population is increasing by leaps & bound in last few decades and highest population growth is found in 1941-51. Major part of water supply comes from ground water so as the population increases parallely the water requirement pressure became on ground water decade by decade. Water level data of last two decade is collected from different places such as Durgapur, Jhotwara, MES Jiapur, Sirsi, Amer, Gopalpura by pass, Mansrovar, Mehona and Surya nagar. Amer and Mehona show an uneven trend of water level but remaining all places show a continuous depleting trend of water level. Average water level of Jaipur urban area was 28.873 meters (mbgl) in 1995; that is continuous decreasing and reached at 47.488 meters (mbgl) in 2010. Over exploration of ground water, less recharging and shrinkage & dryness of surface water bodies are may be the main reasons of this depleting water level so it is suggested to prepare a plan for proper rainwater harvesting and use this water for different purposes in off monsoon season.
