The Kundalika is a small river flowing from the Hills of Sahyadri to the Arabian Sea. This river originates at a small town called Bhira in the Indian State of Maharashtra, 150 km south east of Bombay (Mumbai). The important towns located on the banks of Kundalika are Kolad, Korlai, Chaul, Roha and Salav.
River Kundalika is fed by the excess water from Tata Power's Mulshi Dam Project on to a series of hydroelectric projects and dams, including Ravalje followed by Bhira and then Dholvan, where the water is released in the morning typically at 6 am. The gush of the water reaches Sutarwadi at 7:30 am and water rises at Kolad at 10:00 am.
There exist a historical Trade Route called Savalya Ghat which descends down in Kundalika Valley from Tamhini Ghat Road. Beautifully carved staircases exist at some places & also 2 small water cisterns are encountered.
On the bank of River Kundalika are many retreats and farm houses with mango and watermelon as the chief fruit product and rice and nachni as the chief farm produce as the soil is very rich in minerals and the ample water via canals fed from River Kundalika's clean water.
Over 90% of Kundalika's water is consumed by industries, including RCF's THAL Project and many MIDC all across. This unfortunately has resulted in pollution, especially dues to Roha's Chemical Industries releasing a lot of effluents ( chemical waste ) in the river . On the cards are to use 9000 Quesecs of water by the upcoming Reliance and Essar's new projects in the Villa MIDC. This could kill the rafting besides considerably reducing the river's downstream water levels at Kolad. The river will die a little more and become more placid and shallower.
The Kundalika's water are beginning to get affected and "Save Kundalika Project" is being undertaken by "EcoMantra Nature Awareness and Travel", a local sustainable and community tourism organisation that runs a unique eco camp on its bank at Kolad.
Adventure lovers have found a unique way of enjoying the release of the dam water. Capitalising on the location near Mumbai, with its virtually unending source of adventure lovers, rafting is conducted on the river using the rapids generated by the rushing water released from the dam. Rafting of grade II and III can also be experienced over a 14 km circuit and can be enjoyed all day in the monsoon, or to coincide with the timing of the release of water from the dam during other times of the year. Rafting here is sometimes unavailable in the peak of summer, when the water becomes scarce.
The Planning Commission has given Investment clearance for the scheme –“Upper Kundlika Project (Revised Medium) in Maharashtra”. The project is estimated to cost Rs 154.916 Crore (2009-10 Price Level) and will have to be completed in the financial year 2012-13.
