7.1.21 Ajmer<br />
The district is located in the centre <strong>of</strong> Rajasthan state <strong>and</strong> lies in between 25° 38’ <strong>and</strong> 26° 58’ North latitude<br />
<strong>and</strong> 73° 54’ <strong>and</strong> 75° 22’ East longitude. Ajmer is the third largest city <strong>of</strong> Rajasthan <strong>and</strong> located at the altitude<br />
<strong>of</strong> 486meters above sea level. It is bounded on the north by Nagaur district, on the south by Bhilwara district,<br />
on the east by Jaipur <strong>and</strong> Tonk districts <strong>and</strong> on the west by Pali district. The total area <strong>of</strong> the district is 8481<br />
sq. Km.<br />
There are five rivers which flow thorough the district viz. Banas, Khari, Sagarmati, Saraswati <strong>and</strong> Rupnagar.<br />
Among the important tanks/lakes in the district are Anna sagar, Foy sagar, Phool sagar, Bisala, Ramsar,<br />
Pushkar, Budha Pushkar etc. Temperature ranges from 2° C during winter season <strong>and</strong> 45° C during summer<br />
season. The normal annual rainfall is around 527 mm.<br />
Total 3093 wetl<strong>and</strong>s are mapped including 2022 small wetl<strong>and</strong>s (< 2.25 ha) with 32167 ha area. The<br />
Tanks/Ponds with 14682 ha contributed 45.64% <strong>of</strong> the total wetl<strong>and</strong> area. Rivers/Stream is the second major<br />
wetl<strong>and</strong> category with 6928 ha contributed 21.54%, followed by Reservoirs/Barrages with 6599 ha area i.e.<br />
20.51 %. Thus, the district is dominated by man-made wetl<strong>and</strong>s.<br />
Open water spread <strong>of</strong> the wetl<strong>and</strong>s is significantly higher in post monsoon (14663 ha) than during pre<br />
monsoon (2928 ha), indicating the rainfall dependence <strong>of</strong> the wetl<strong>and</strong>s in the state. Aquatic vegetation during<br />
post-monsoon <strong>and</strong> pre -monsoon are 153 ha <strong>and</strong> 98 ha respectively. The qualitative turbidity <strong>of</strong> water is low<br />
in post <strong>and</strong> high in pre monsoon season. Details <strong>of</strong> estimates <strong>of</strong> wetl<strong>and</strong>s in Ajmer are given in Table 26.<br />
