Tonk district forms the shape of like kite or rhombus with its eastern and western sides bending somewhat inward and the south-eastern portion protruding between Sawai Madhopur and Bundi districts. The district is flat at a general elevation of about 214.32 meters above sea level with rocky but scrubby hills. The soils are fertile but somewhat sandy and the subsoil water is limited. The distinguishing feature of Tonk district is the Aravali system, which starts from Bhilwara district and running along the boundaries of Bhilwara and Bundi districts, enters Tonk district in the south near Rajkot and continues in a north eastern direction until it leaves the district near Banetha. A second chain lies in Tehsil Todaraisingh between the head quarter of the Tehsil Rajmahal where the Banas River flows through this hill. Another important hill is near Malpura and a small hillock near the border of Tehsil Sarwar of district Ajmer.
The rivers and streams of this district belong to the Banas system, which is more or less nonperennial. During Monson and for a few months thereafter new streams appear and retain water in hollows at some places. Though is not of much use direct irrigation but helps irrigation by raising the sub-soil water level of wells. Banas River enters Tonk district at Negdia in Deoli Tehsil and from this place it takes a serpentine course, dividing the district in roughly two third to its west and north and one third to its east and south. Its total length is 400 Km. It is fordable during winter and summer but during the rains becomes a swift and angry torrent. Negdia , Bisalpur, Rajmahal, Deopura ,Mahendwas and Shopuri are the important villages on the bank of this river . Manshi the principal tributary of Banas travels along the borders of Jaipur and Tonk district between the Tehsils of Malpura and Phagi until it turns south to join the Banas at Galod village. The Sohadra is another important river as it feeds the Tordi sagar Tank, the biggest irigation tank in Rajasthan. It joins Mashi near village Dundia and thereafter meets, Banas River near village Galod. Other small river are khari, Daian , Bandi and Galwa which join Banas and Mashi river at Negdia , Bisalpur , Chaturpura and Chouth-ka-Barwara respectively.
There is no natural lake in the in the district. However, several tanks formed by harnessing the feeders of the Mashi and the Banas are available. The biggest of such tanks is Tordi sagar in Tehsil Malpura irrigation an area of more than 5 thousands hectares, followed by Bhairon Sagar irrigating an area of about 1295 hectares. Others are very small tanks which have individually a very small area.
The Bisalpur Dam situated 17 Km. from Deoli. The water storage capacity of this dam is 315.50 meter. Apart from providing water to Jaipur, Ajmer, Nasirabad, Beawar, Kishangarh etc. this dam provides irrigation facilities to Deoli, Tonk, & Uniara Tehsils. Due to this dam, subsoil water level has risen in Deoli, Tonk, Malpura and Toda Raisingh which resulted in increasing the fertility of soil and yield of crops.
