Waterways have historically been the lifeblood of Dhaka, shaping its trade, geography, and culture.
* **Buriganga River:** Flowing past the southern edge of the city, this river is the historical gateway to Dhaka and remains a bustling, albeit heavily polluted, artery of commerce. The Sadarghat river port is a chaotic, fascinating hub of ferries and country boats. * **Surrounding Rivers:** The city is bounded by the **Turag River** to the west, the **Balu River** to the east, and the **Shitalakshya River** further southeast. * **Urban Lakes:** Internal waterways like **Gulshan Lake**, **Banani Lake**, **Dhanmondi Lake**, and **Hatirjheel** serve as crucial drainage basins and recreational zones for residents.
