This is a small balancing Reservoir with gross capacity is 557 Mcft. The water that is received from Prambikulam Reservoir and from the Peruvaripallam Reservoir, as well as from its own catchment, is diverted to the Sarkarpathy Power House through the Sarkarpathy Power Tunnel.[2] The Peruvaripallam Dam is connected to the Parambikulam Dam by a canal [3][4] through a 2.5 km (1.6 mi) long underground tunnel. The Poringalkuthu reservoir gets water from catchments downstream of Parambikulam and Thunakadavu dams.[5]
Reservoir
edit
An adjacent canal also flows from this river to the reservoir. Reservoir attracts fishing businesses. Tourism is also developed around the Reservoir.[6] Water from Parambikulam dam drains to Thoonakadavu by gravity and after generation of 30 mW power at Sircarpathy, it will go through a Canal to reach Thirumurthi Dam.[7]
Sharing of water
edit
The water stored in the dam reservoir is used mainly for agriculture. Kerala needs to get water every year from The Parambikulam-Aliyar project and Tamil Nadu will provide 7.25 TMC from the proposed project.
