7.1.14 Nagaur
Nagaur is the fifth largest district in Rajasthan with a vast topography spreading over 17,718 sq. kms. It lies in
between 26 0 25 ’ to 27 0 40’ degrees North latitude and 73 0 10’ to 75 0 15’ degrees East longitude. Its landscape
is a good combination of plain, hills, sand mounds & it is also a part of the great Indian Thar Desert. The
average rainfall is 36 cm. The maximum temperature touches 46 0 whereas the minimum temperature 3 0 C.
Total 2348 wetlands are mapped including 2004 small wetlands (< 2.25 ha) with 30876 ha area. The
Lakes/Ponds with 16024 ha contributed 51.90% to the total wetland area. The Rivers/ streams with 7016 ha
(22.72 % area) is the second major wetland category, followed by Salt pans with 3030 ha area i.e. 9.81 %.
Thus, the district is dominated by man-made wetlands.
Open water spread of the wetlands is significantly higher in post monsoon (12971 ha) than during pre
monsoon (10080 ha), indicating the rainfall dependence of the wetlands in the state. The qualitative turbidity
of water is high in both the seasons. Details of estimates of wetlands in Nagaur are given in Table 19.
