Waterways define the geography and agricultural life of Silvassa.
* **Daman Ganga River:** This major river flows directly through the city, providing a scenic backdrop and dividing the landscape before eventually emptying into the Arabian Sea at Daman. * **Madhuban Dam Reservoir:** Located downstream, this massive dam creates the sprawling Dudhni Lake. It serves as a vital source of water for irrigation and drinking, as well as a prime destination for aquatic tourism.
