The proximity to the Himalayan foothills and the torrential monsoon rains has resulted in the prosperity of the mighty rivers in Nagaland. The rivers form an integral part of the geography of Nagaland. The mountain region is the source of several streams and rivulets. The tributaries of the great Brahmaputra River flow through the state to join the main river before reaching its mouth in the Bay of Bengal.
Nagaland state is drained by four main rivers. One of the chief tributaries of the Brahmaputra River is Dhansiri which originates in the mountainous Laisang peak in Nagaland. The districts of Nagaland receives water from the Dhansiri river prior to its confluence with the Brahmaputra River.
Three other rivers of Nagaland are the Dikhu, Doyang and the Jhanji. The four chief rivers of Nagaland form huge catchment areas. The rich alluvial deposit of the rivers facilitates crop cultivation in the state. The government has also set up power stations in order to generate hydroelectricity from these rivers. Fishes breed in the fresh mountain waters of the Nagaland rivers.
