Lakes 'n Reserviors

    The Western Ghats form one of the three watershed of India, feeding the perennial rivers of peninsular India. Important rivers include the Godavari, Krishna, and Kaveri. Rivers that flow to the west drain out into the Arabian Sea. These rivers are fast-moving, owing to the short distance travelled and steeper gradient. Important rivers include the Mandovi, Zuari, and Periyar. Many of these rivers feed the backwaters of Kerala and Maharashtra. Rivers that flow eastwards of the Ghats drain into the Bay of Bengal. These are comparatively slower moving and eventually merge into larger rivers such as the Kaveri and Krishna. Smaller rivers include the Chittar River, Bhima River, Malaprabha River, Manimuthar River, Kabini River, Kallayi River, Kundali River, Pachaiyar River, Pennar River, and the Tambaraparani River.

    Fast running rivers and steep slopes have provided sites for many large hydro-electric projects. There are about major 50 dams along the length of the Western Ghats with the earliest project up in 1900 near Khopoli in Maharashtra. Most notable of these projects are the Koyna Dam in Maharashtra, the Parambikulam Dam in Kerala, and the Linganmakki Dam in Karnataka. The reservoir behind the Koyna Dam, the Shivajisagar Lake, is one of the largest reservoirs in India with a length of 50 km (31 mi) and depth of 80 m (262 ft)
