Program Name: VISIT TO Koyna Dam – Lake Tapping, Humbarli(Civil Engineering Department)
Program Date: 15th jan. 17
Venue: Koyna Dam – Lake Tapping, Humbarli, Maharashtra.
The Koyna Dam is one of the largest dams in Maharashtra, India. It is a rubble-concrete dam constructed on Koyna River which rises in Mahabaleshwar, a hillstation in Sahyadri ranges. It is located in Koyna Nagar, Satara district, nestled in the Western Ghats on the state highway between Chiplun and Karad.
Koyna river is a major tributary to Krishna. Koyna originates near Mahabaleshwar township
which is a famous hill station in Sahyadri Range. Unlike other rivers which flow either eastward
or westward immediately after origin, Koyna river flows in a north – south direction almost
parallel to the continental divide for a distance of 65 Kms. from Mahabaleshwar to village
Helwak, skirting King Shivaji’s fort Pratapgadh. At village Helwak, it turns sharply eastwards,
travels for about 56 Kms and joins River Krishna at Karad. It’s a peculiar confluence where both
the rivers meet head on. This confluence is aptly named as Preeti Sangam.
