River valleys served as the preservers of civilization in alternate spheres of the globe. Water forms the quintessential element in agrarian and human activities in Kerala, which formed a part of India, water resources originating from Western Ghats and flowing towards the sea was a favourable condition. This restricted the people in occupying the plane areas. Right now, there are forty four rivers in Kerala. In the ancient period, there existed much more number of rivers. Kerala's geographical nature is a proof of its existence below water. Paleo- channels and lagoons formed part of its resources. The floods were threat to our ancesters. These took away everything to the river or to the sea. Travancore has got plenty of rivers. At present, eight rivers are flowing there. Vizhinjam, a part of Travancore lacks rivers now. Gangayar, a small canal, which springs from the Western Ghats is the sole remains as part of historical existence. Yet another minute stream joins Vizhinjam near Mulloor. At present, the work of the international sea port is proceeding there. There are ample evidences in the satellite studies and deep geological studies of the presence of three big rivers in the Vizhinjam area in the past. Ground evidences substantiated the study. A bastion, in the form of the Western Ghats, exists amidst Kerala and South Indian areas. As we move forward to the southern tip of Kerala, in Trivandrum. It can be equated to a water bastion or an enormous water tank, which has the capacity to bear rich quantities of water. The water is being emitted out via various canyons. These gorges appear in the spot where the present dams are found. These spots are specifically Thenmala, Peppara, Neyyar, Pechippara. All these form part of Thiruvananthapuram district, in Kerala and Kodayar and Keeripara, in the Kanyakumari district. Water seeps out of these gorges, branching out to numberless rivers. These rivers ran their courses, formed tributaries and later co- mingled at different points. Neyyar, Pechippara and Kodayar dam locations are located in these openings, specifically at Thenmala, Agastyamala and Peppara. The rivers evolving via these openings established a network of water canals. Vizhinjam was one among the water outlets that moved to the Arabian Sea. Large quantities of water flowed into Vizhinjam Sea through here. Thenmala, a spot in the northern border of Thiruvananthapuram and Keeriparain, in the southern border of Thiruvananthapuram have a length of approximately 125 kilometres. The areas create a reservoir of water, above the Western Ghats, with its numerous outlets. They take the form of many rivers and flow to the Arabian Sea. They make its course in a zig-zag format, as a result, they join together at various places before they reach the Arabian Sea. These rivers are of much advantage to Southern Travancore. The fertility of the spot is certainly due to the river. This, in turn, hiked the production of pepper and other spices. The next advantage is that they ensure navigational spaces for boats. Those boats could easily pass through these spots. Luckily, Vizhinjam was one among such spots which can be reached smoothly with the help of rivers, across 125 kilometres of Western Ghats.
