Banganga River, an 240 km long tributary of Gambhir river in India, originates from the hills of Aransar and Bairath (Virat Nagar) in Jaipur region of Rajasthan state and converges with Yamuna near Fatehabad in Agra district of Uttar Pradesh state.

[3][4][5] The river basin has 596 mm rainfall and 95% of which falls during the four monsoon months from June to September.

[2] Within Rajasthan, its drainage basin fully or partially covers 30 Community Development Blocks (CDB) with 2,473 towns and villages in Alwar, Jaipur, Dausa, Sawai Madhopur and Bharatpur districts of Rajasthan.

[citation needed] Fairly recently, within 30 years, these areas were vibrant and arable with different types of agriculture .

[citation needed] There were significant areas of forest along the Banganga's route and earlier it was known for the cultivation of dates in Maid (a town based on the river bank) but with the dropping water levels the date farming has suffered.
