Spillway
editSpillways are Ogee-type and are 5 in numbers. Vertical lift, each of size 5.18 x 2.74 m is fitted on the spillways.[1]
Location
editThe location of the dam is at a distance of 20 km (12 mi) from Munnar.[4] It is a major tourist destination near Munnar. Kundala dam is located on the way to Top Station. Tourist places like Pampadumchola National Park, Kurinjimalai Sanctuary and Meesappulimalai are close to this dam.
Reservoir
editFull Reservoir Level (FRL) is 1,758.7 m (5,770 ft) and Minimum Drawdown level (MDDL) is 1,735.84 m (5,695.0 ft).[1] Effective Storage at FRL is 77,870,000 m3 (2.750×109 cu ft) and Generation potential at FRL is 22.74 MU. The water stored in the Kundala reservoir is released through the Palar River to Mattupetty dam located downstream. The water stored in the Mattupetty reservoir is released to downstream via a canal to a power house. Kundala reservoir has become a tourist spot.[5]
Hydroelectric project
editPallivasal Hydroelectric Project, which is the first hydroelectric project in Kerala, uses the water from Kundala dam.[6] The project was completed in two stages. In the first stage, just a run-of-the-river scheme was initially introduced with three units having capacity of 4.5 MW each. The first unit of the Pallivasal power station was commissioned on 19 March 1940. The second unit on 2 February 1941 and the third unit on 19 February. Kundala and Mattupetty dams together contributed about 65,000,000 m3 (2.3×109 cu ft) of storage.[7]
