Waterways define the geography and the soul of Guwahati.
* **Brahmaputra River:** The city's northern edge is entirely framed by this massive, braided river. It provides transportation, sustenance, and scenic beauty, though it also brings seasonal floods. * **Deepor Beel:** A massive wetland system in the southwestern part of the city. * **Historic Pukhuris (Ponds):** The city features several historical tanks excavated by ancient kings, including **Dighalipukhuri**, **Jorpukhuri**, and **Silpukhuri**, which now serve as tranquil urban oases.
