The Western Ghats have several manmade lakes and reservoirs. The well known lakes are the Ooty (2500 m altitude, 34.0 ha) in Nilgiris, and the Kodaikanal (2285 m, 26 ha) and the Berijam in the Palani Hills. The Pookode lake of Wayanad in Kerala at Lakkadi is a beautiful scenic one with boating and garden arrangements. Most of the bigger lakes are situated in the state of Tamil Nadu. Two smaller lakes, the Devikulam (6.0 ha) and the Letchmi Elephant (2.0 ha) are in the Munnar range. The majority of streams draining the Western Ghats and joining the Rivers Krishna and Kaveri carry water during monsoon months only and have been dammed for hydroelectric and irrigation purposes. The major reservoirs are: Lonavala and Walwahn in Maharashtra; V.V. Sagar, K.R. Sagar and Tungabhadra in the Malenadu area of Karnataka; Mettur Dam, Upper Bhavani, Mukurthi, Parson's Valley, Porthumund, Avalanche, Emerald, Pykara, Sandynulla, Karaiyar, Servalar, Kodaiyar, Manimuthar Dam and Glenmorgan in Tamil Nadu; and Kundallay and Maddupatty in the High Range of Kerala. Of these the Lonavla, Walwahn, Upper Bhavani, Mukurthi, Parson's Valley, Porthumund, Avalanche, Emerald, Pykara, Sandynulla, Glenmorgan, Kundally and Madupatty are important for their commercial and sport fisheries for trout, mahseer and common carp.
