Geography

The Brahmaputra river flows to the north of the metropolis. The city is bordered on the south by the foothills of the Shillong plateau and to the east by the Amchang Wildlife Sanctuary. The Bharalu River, a tributary of the Brahmaputra, flows right through the heart of the city. To the south-west of the city lies Dipor Bil, a permanent freshwater lake with no prominent inflows apart from monsoon run-off from the hills to the south of the lake. The lake drains into the Brahmaputra, 5 km (3.1 mi) to the north, and acts as a natural stormwater reservoir for the city. There are also multiple hills within the city limits.
