Pennar Basin

Pennar Basin extends over an area of 55,213 km2 which is nearly 1.7% of total geographical area of the country. The basin lies in the states of Andhra Pradesh (48,276 km2) and Karnataka (6,937 km2).

Pennar river rises from the Chenna Kesava hills of the Nandi ranges of Karnataka and flows for about 597 km before outfalling into Bay of Bengal. The principal tributaries of the river are the Jayamangal, the Kunderu, the Sagileru, the Chitravati, the Papagni and the Cheyyeru.

The important soil types found in the basin are red soils, black soil, sandy soil and mixed soil.

An average annual surface water potential of 6.3 km3 has been assessed in this basin which is completely utilisable. Culturable area in the basin is about 3.5 Million ha, which is 1.8% of the total culturable area of the country.

Present use of surface water in the basin is 5.0 km3. Live storage capacity in the basin has increased significantly since independence. From just about 0.1 km3 in the second plan period, the total live storage capacity of the completed projects has increased to 2.4 km3. In addition, a storage quantity of over 0.1 km3 would be created on completion of projects under construction.
