Topography of the basin, reservoirs and command area
Like all the river basins in Kerala, the Pamba basin also can be divided into three natural zones based on elevation, consisting of low land or seaboard, midland and high land. The coast for a short distance along the borders of lakes is flat, retreating from it the surface roughens up into slopes which gradually combine and swell into mountains on the east. The low land area along sea coast is generally swampy and liable to be flooded during monsoon inundation. The plains/midlands succeed low land in gentle ascents and valleys interspersed with isolated low hills. The high land on the eastern portion is broken by long spurs, dense forests, extensive ravines and tangled jungles. Towering above all their slopes are Western Ghats that form eastern boundary of the basins.

Water for farming, such as paddy fields, is scarce. Experts are calling for governmental awareness of the dire situation and the need torein in development that is destroying the environment. The Kerala High Court has initiated steps to control the pollution of the river from the practice of some visitors to Sabarimala who throw their clothes into it. As part of the Punyam Poonkavanam project, pilgrims have been exhorted to avoid the usage of soap and oil while bathing in River Pamba. They are also requested not to throw any material, including clothes, to this holy river. At a broader level, this project aims to spread the message of cleanliness and greenness beyond Pamba and Sabarimala.
