The landscape around Nongpoh is fed by several monsoon-fed streams and rivers.
* **Umtrew River:** This significant river flows through the Ri-Bhoi district near Nongpoh. It is a vital water source for the region's agriculture and is popular for local fishing and riverside picnics. * **Proximity to Umiam:** While further south toward Shillong, the massive Umiam Lake (Barapani) reservoir is the defining water body of the region and deeply connected to the watershed of the Ri-Bhoi district.
