Surma River
The Surma River is a major waterway in northeastern Bangladesh and a key component of the Surma-Meghna river system. It originates at the Indian border where the Barak River divides into two branches, the Surma and the Kushiyara. The river traverses the fertile Sylhet Basin, a region famous for its sprawling tea estates and unique wetland ecosystems known as haors. The Surma serves as a vital artery for local commerce and transport, particularly for the stone and limestone industries centered around Sylhet city. Each year, the region experiences some of the highest rainfall in the world during the monsoon, often causing the Surma to overflow and submerge vast tracts of the surrounding lowlands. These seasonal floods are critical for replenishing soil nutrients and maintaining the biodiversity of the haor fisheries. In recent years, increased sedimentation due to upstream deforestation and unregulated sand mining has threatened navigability and exacerbated flood risks. Culturally, the river is deeply ingrained in the regional identity of Sylhet, frequently appearing in local folk music and literature.
