Submerged Madenur dam in Linganamakki backwaters

Until the day I received an email from my acquaintance Jayachanda N S from Shimoga, I'd never heard of a dam submerged in a reservoir of another dam. The email was an invitation to a trip to this submerged dam of Madenur. Unfortunately, I could not make it to the trip but Jayachanda shared some photos of the place. June end I chatted with Jayachanda on phone and requested his permission to post his pictures here.. yes.

Madenur Dam, also known as Hirebhaskar dam was built across river Sharavathi between 1939 and 1948. The dam was inaugurated in 1949 and remained functional until the much larger Linganmakki Dam came into existnce in mid 1960s. Now Madenur Dam remains submerged in the waters of Linganmakki reservoir only to surface when the water level dips during peak summer month of May. With some more research, I found Rajesh Naik's post on dreamroutes.org and learnt how the dam functioned.

The construction of Madenur dam was supervised by a civil engineer names Ganesh Iyer from the Old Mysore region. He was an expert in construction of structures based on the siphon system. The 1150' (350 meter) dam has 11 siphons, each 18' wide x 58' high. The mechanism of siphon system enables water to flow out of the reservoir automatically when it reaches the optimum level. Besides the siphons, there are 3 crest gates

Here we go- the wonderful Madenur Dam which has survived 50 years of remaining submerged. In this view the river flows from left to right. The first siphon from the east end.

The siphon top. One can walk on the 2' wide bridges connecting the siphons but it can be very risky.

The stairway connecting the dam crest to the siphon platform.

The pillars around siphons. Each siphon has an outer ring of 12 pillars. The inner wall is the well through which water flows out.

The cement structure has survived the test of time and water. Appreciate the project team's work.

The domes of the siphon; whoever designed this structure had a sense of aesthetics too.

Finally, the twelve siphons in a single frame.

The other side of the dam.. i.e. the tailrace. It is said there's an ancient temple submerged close to this dam.

Jayachanda locates a herostone.. some where on the reservoir bed.

My thanks to Jayachanda for these lovely snaps. Hopefully, one day I shall make it to this place and the nearby forts of Nagara and Kaveledurga.

Oh this architecture is really inspiring. It is very seriously and devotedly designed and created. Thanks for sharing. Liked both the interior and external pics, gave a good complete picture. If someone could pose in them, the scale could be more evident. The builder/architect seems to have taken some aesthetic clue from fort bastions - perhaps may be belonging to this regions and spent some time observing or being with forts!
Siddeshwar, if you do plan Kavaledurga, do let me know, I may send you a secret map of locations you wont want to miss in that hill. If you go to Nagara, I think Devaganga ponds (Basavabaina village) is near.

ಒಂದು ಡ್ಯಾಂ ನಲ್ಲಿ ಇನ್ನೊಂದು ಡ್ಯಾಂ ಮುಳುಗಿದೆ ಅನ್ನೋದೇ ಆಶ್ಚರ್ಯದ ಸಂಗತಿ. ಇದನ್ನು ಸೊಗಸಾದ ವಿವರಣೆಯೊಂದಿಗೆ ಪ್ರಸ್ತುತಪಡಿಸಿದ ಸಿದ್ದೇಶ್ವರರವರಿಗೆ ಧನ್ಯವಾದಗಳು. ಜೊತೆಗೆ ಇದರ ಬಗ್ಗೆ ಮಾಹಿತಿ ಹಂಚಿಕೊಂಡ ಜಯಚಂದರಿಗೂ ಧನ್ಯವಾದಗಳು.

ಸಿದ್ದೇಶ್ವರರೇ, ನಿಮ್ಮ ಯಾತ್ರೆ ಮುಂದುವರಿಯುತ್ತಿರಲಿ. ನಮಗೇ ಗೊತಿಲ್ಲದ ನಮ್ಮ ನಾಡಿನ ಇತಿಹಾಸ ತಿಳಿಯುತ್ತಿರಲಿ. :)

@Nikhil - you are so right, the dam does have likeness to a bastion, designed by heart and mind. Its my long wish to see the forts of this region. If you can share the map, it would be great! Now I'm curious to see the secret map.. did you make it yourself.

@Ganesh - thanks for your kind wishes.
