Introduction
Banganga River Basin is located in the northeastern part of Rajasthan, between latitudes 26o40' and 27o37' and longitudes 75o49' and 77o39'. It lies between the Gambhir and Banas Basins to its south-southwest, Ruparail and Sabi to its north, and the Shekhawati Basin to its west. Its eastern edge borders the Yamuna River Basin in Uttar Pradesh.

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.

Drainage
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.

Rainfall
The mean annual rainfall over Banganga Basin was computed as 596 mm, of which about 95% fall during the four Monsoon months (June-September)

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.
