It is situated in the foothills of Eastern Himalayas and also very high-risk zone as regards seismicity. Dhemaji was once famous for fish of various varieties. It was also a good source of milk. Still many varieties of fish are found in the rivers and rivulets in the region. It has some very good spots of natural beauty and richness but most of them are yet to be unveiled by the outsiders.
