Waterways define the geography and agricultural wealth of Vijayawada.
* **The Krishna River:** The lifeline of the city, dividing it from neighboring Guntur district. It provides drinking water, irrigation, and spiritual significance. * **Prakasam Barrage Reservoir:** Forms a vast, scenic lake-like expanse just upstream of the city. * **The Three Canals:** Vijayawada is uniquely crisscrossed by three major irrigation canals—**Eluru Canal**, **Bandar Canal**, and **Ryves Canal**—which originate from the Prakasam Barrage and run through the heart of the city.
