Banganga River
Basin extends over parts of Alwar, Jaipur, Dausa, Sawai Madhopur and
Bharatpur Districts.
The total catchment area of the Basin is 8,878 km2 according to 1:250,000
scale topographical maps published by the Survey of India.
Orographically, the western part of the Basin is marked by hilly terrain
belonging to the Aravali chain, with fairly flat valleys along the Banganga
River and its tributaries. East of the Todabhim - Mandawar chain of hills
lies an extensive alluvial plain which gently slopes eastwards, towards the
Yamuna River in Uttar Pradesh. The northeastern part of the area is also
rather flat, interspersed with moderately elevated hills.
The main urban agglomeration in Banganga River Basin is Bharatpur city
situated at the eastern edge of the Basin. The second largest urban centre
is Dausa.

River Banganga originates in the Aravali hills, near Arnasar and Bairath in Jaipur District. It flows towards the south up to the village of Ghat, then east through partly hilly and partly plain terrain. The total length of the river is 240 km. The main tributaries are Gumti Nalla and Suri River, joining the river on its right bank, and Sanwan and Palasan Rivers, meeting the river on its left bank.

Existing Surface Water Projects
There is one Major irrigation project (Ramgarh, presently operating only as a water supply scheme), 10 Medium and 177 Minor irrigation projects in Banganga River Basin, as well as several small irrigation systems (covering less than 20 ha) constructed and operated by Panchayat Samities (PS).
Ongoing Surface Water Projects
One minor irrigation project with a total live storage capacity of 0.6 Mm3 is under construction in Banganga River Basin. An additional area of 248 ha. will be irrigated upon completion of this project.
Proposed Surface Water Projects
8 minor irrigation projects with a total storage capacity of 10 Mm3 have been proposed by the ID in this Basin. An additional area of some 2,700 ha will be irrigated after completion of these projects.
