It started heavily even in Thiruvananthapuram. Heard that Mudirapuzha arm of Periyar receiving heavy rainfall and Madupetty Dam shutters are opened. Mullaperiyar is at 136.60 ft at 12noon today. #KeralaFloods
The water from Madupetty Dam will flow through Munnar to Kallarkutty and Lower Periyar Dams and will join Bhoothankettu Barrage in Periyar River..
Mudirapuzha arm of Periyar is used to receive heavy rainfall. This sub basin along with Mullaperiyar catchment created great havocs in 1924 and 1961 floods.
It seems Mullaperiyar getting filled fast

Water level today

6AM - 136.10 ft
8AM - 136.20 ft
10AM - 136.40 ft
12Noon - 136.60 ft
1 PM - 136.80ft
Understand the Mudirapuzha arm of Periyar.

It has 6 reservoirs viz. Kundala, Madupetty, Anayirankal, Ponmudi, Sengulam, Kallarkutty.
But these 6 reservoirs having 162.40 MCM (5.74 TMC).

To get a perspective, please understand that live storages of other reservoirs in the Periyar

Idukki -1460 MCM
Idamalayar-1018 MCM
Mullaperiyar- 271 MCM
It seems Mullaperiyar getting filled fast

#Mullaperiyar reservoir water level at 5 pm is 137.50 ft, at this rate of inflow continues, the reservoir may reach its Full capacity within 26 to 27 hours. Crisis management decided to start evacuation of people as spill of the reservoir is imminent #KeralaFloods
#Mullaperiyar water level at 137.70 ft at 7 PM.

1.6 ft rise in last 13 hours.
0.6 ft rise in last 4 hours.

People are requested to fully co-operate with District/Disaster Management Authorities, as the chances of spill from the reservoir is imminent, if inflow is not reduced

So be alert
Mullaperiyar Update 10:30 PM

Water level 138.70 ft.

Inflow is heavy, at this rate expect opening of spillway gates any time in next 7-8 hours.
Mullaperiyar Update 11:00 PM

Water level 138.85 ft.
Mullaperiyar is not having any flexibility like Idukki both is having almost equal catchment areas.

Mullaperiyar - 624 sqkm
Idukki- 625 sqkm

Mullaperiyar storage is just 20% Idukki storage, so Mullaperiyar will swell much faster. This reservoir is not having the flexibility!
That is one major reason, we are asking don't raise reservoir level. We allowed TN to increase tunnel size from 1300 cusecs to 2200 cusecs in 1954 and hence TN able to draw 96% of water from this reservoir even at 136 ft.
So after the diversion tunnel size increase and Vaigai reservoir, the quantity of water taken from Mullaperiyar has increased and the spill is reduced.

But when emotions are in play, no one want to listen to the facts.
Mullaperiyar touched 139 ft at 11:30 PM, some small reduction in inflow now. But we are crossing fingers
In no reservoir, we can't take 100% water, even giants like Idukki, Mettur etc are also spilling.

We need flexibility of operation, we cant release water irrationally.This is one reason, we started operating Idukki at 2400 ft before it's FRL of 2403 ft while Dam top is 2415 ft.
Leave all issues or whether Dam is structurally or seismically safe. We should see it's hydrological flexibility. What gain we will active when we are able to utilise 96% of inflow in the catchment with present storage? Hardly less than 1% increase in utilisation from 136 to 142
Mullaperiyar Update
@12:00 PM

Lake level : 139.15 ft

This is to clarify to the media that TN is taking water at it's full capacity of tunnel at 2200 cusecs and there was no reduction in intake. Water level increase is due to heavy rainfall in the catchment.
District Collector, Idukki informed that evacuation of people from downstream of Mullaperiyar Dam is completed. Dam Spillway will be opened soon and TN will open it when its closer to 140 ft.
#Mullaperiyar Dam may be opened at tonight 1:30am as the inflow is heavy. Supervisory Committee Chairman is now in the loop
No one is sleeping tonight. All Senior Secretaries, SDMA people, KSEBL Chairman, Chief Engineers of KSEB and Irrigation Dept, All District Collectors, Police, Revenue..We all are in the loop, each minute is updated and collective decision making is happening. Of course, I am too
Idamalayar spill will be 22,000 cusecs and Idukki spill will be 26500 cusecs..

Kallar, Idukki's augmentation started spilling. Lower Nirar Dam, TN is spilling to Idamalayar
Idukki inflow touched a whopping 1817 cumecs or 64000 cusecs. This is now equal to what recorded there at 1961!

KSEB seeking sanction to release 24000 cusecs from the Kakki reservoir and 7000cumecs of water from Pamba dam in to the Pamba River. #KeralaFloods
Revenue Additional Chief Secretary and Chairman, KSEB are not even blinking. We all brainstorming how to handle this deluge. Kerala's bureaucracy is setting example here

Banasurasgar rain is reduced. Some comfortable news from Wyanad
Mixed news!

Idukki inflow getting reduced to 43,600 cusecs from 64,000 cusecs!

Meanwhile Mullaperiyar inflow increased to 30200 cusecs from 23,000 cusecs.

#Mullaperiyar at 1am is 139.50 ft
#Mullaperiyar further raised to 139.70 ft @ 01:30 hrs, at this rate it will reach 140 ft by 2:30 hrs and TN will start release from that point.
Learnt that Ullunkal Pvt Small HEP in Pamba River basin is sank in today's flood.
KSEB Chairman deserves a salute, still with the State's emergency response team. He is not ready to take any rest..Just staying with we engineers and scientists in the team
Our Engineers manning dams in Chalakudy basin deserves a standing ovation. They are doing their best to balance between Kerala Sholayar and Poringalkuthu. Even when water level in Poringalkuthu reached danger levels, they keep cool and acting their professional best.
None of the District Collectors are sleeping..

See message from a DC

"Announcement is going on. Tahsildars and vos are already in the field . Police is also alerting people."

TN flood warning #Mullaperiyar
Mullaperiyar update:
11 shutters raised upto 1 feet and releasing 4500 CFS water.
We are planning for increasing Idukki discharge considering Mullaperiyar spill coming fast to Idukki Dam. It will reach Idukki by tomorrow morning 7.30 AM
In a flood like this magnitude, power draft becomes irrelevant. For Idukki inflow of 64000 cusecs, compare power draft of 4000 cusecs. For Mullaperiyar inflow of 30200 cusecs, consider tunnel draft of 2200 cusecs
Malankara Dam which receives Idukki PH tailwaters

Around 10 TMC of water is already spilled from Idukki reservoir since it's opening #KeralaFloods ,which is almost 20% of its live storage capacity
Its an overwhelming experience to see that how KSEB Chairman & Managing Director Sri. N.S. Pillai IA&AS encouraging and standing by his team of Engineers. Like a true leader he is leading them from the front. I am so proud of my parent organisation 👍

None of the Engineers in our generation seen such a flood and that did not deter our determination to manage this crazy deluge, we are stretched to our limits, but we enjoy doing this for our people. It's not what you learn in Engg College, it's the practical wisdom!
Now #Mullaperyar spillway release is 9000cusec. It will be increased to 15000 in another 1hr.

#Mullaperiyar almost reached 142 ft! My field team reports ..
After restricting the spill to 3330 cusecs and after brought #Mullaperiyar Dam to 142 ft, TN suddenly increase spillway discharge to 10,000 cusecs!!

Some #Demonetisation thoughts!

Many here asked me why I am not reacted to the latest RBI Annual Report which exposed DeMon as nothing but a perverted dream of a Tughlak.

First of all there was nothing surprising elements there for me!!
Then everyone was discussing the amount of 99% returned to the system! Some sigh of relief as our Urjit stop counting, but I don't get any evidence that he has stopped that!!

Because still we hear about old SBN notes are seized by agencies ;)
Annual Report 2017-18 of the RBI that Rs.15.311 trillion Specified Bank Notes was returned. While RBI in its AR in 2016-17 itself admitted that as of June 30, 2017, received Rs.15.28 trillion of SBN. 

Total SBN demotenised was Rs.15.44 trillion

99.2% vs 99.0% is a big deal?? 😉

IMD started issuing alerts "be prepared" from August 8! "For action" was issued on August 9.

At least glad that IMD admitted that their alerts were that close.

Also thank you for not claiming that they have issued alerts for "extreme rainfall" and only "heavy rainfall" then
I scanned all those reports of this regional office issued. NOWHERE I SEEN AN EXTREME RAINFALL EVENT ALERT. Each Monsoon season IMD used to issue HEAVY TO VERY HEAVY RAINFALL alerts and small reservoirs used to spill and the spate will be comfortably negotiated by the rivers
Please understand the nuances. We can negotiate a heavy rainfall event, whatever allowances in the dams and river channels are sufficient to negotiate that one. You will see some flooding, may be a knee deep one & dams spill w/o any problems

"In Kerala, there’s no reason to damn the dams" here is my answer to all pundits who are preaching an early opening of Idukki would have saved the flooding of Periyar..

Read it slowly and understand the nuances! nationalheraldindia.com/india/in-keral…
Grab the hardcopy and read @NH_India
I felt depressed when a person who served as the Director of the prestigious IITM says that he has given warning & Kerala has no respect for his warning but Odisha has!!
Oh boy!! I am at a loss if you cant discern cyclones in East coast and extreme rainfall in Western coast

With due respect to his credentials as an expert environmentalist, I differ with him, because this is a repeat of 1924 and this type of extreme events will occur with an annual exceedence probability of 9.52% in a span of 100 years!

Extreme floods is not his area of expertise!
In our country, we have a habit of people and experts venture into the uncharted territory where they have no domain knowledge.

I can't/will not comment on ecology or environment because it's not my domain. I read and understand but never make sweeping statements about that
What about the 1924 flood? When Kerala had no encroachment and had one foruth of the population than now?

Now the scientific evidence shows that this 2018 is a repeat of 1924!! Nature has it's crazy behaviour.

Gadgil is right about landslides but not about floods. Sorry!

I am ready for a debate with any of these experts who are blaming KSEB for mismanagement of dam operations.

Stop sweeping statements! Come out with data and talk sense!

Don't lead a literate society to blind spots!!
When our catchment areas had experienced one third of the annual rainfall within 4 days pinch yourself...Can you believe it?

& the Engineers managed efficiently and contained these floods even when you had a 1 in 1000 year flood!

Please don't destroy their morale!!
This is the hard evidence of 4 days of non-stop extreme rainfall

Idukki -811mm (Idukki Dist)
Pamba - 344 mm (Pathanamthitta Dist)
Kakki - 915 mm (Pathanamthitta Dist)
Kuttiyadi - 954 mm (Kozhikode Dist)
Idamalayar - 644 mm (Ernakulam Dist)

Damn Dams!!

They created all hell in Kerala......

How many dams are there in Achecoil, Manimala & Meenachil which created havoc in Central Kerala?


How much yield of Pamba River is impounded in the dams there?

JUST 10.4%

Blame it on dams!!
Come to the Northern Kerala.....

There you have the Great Chaliyar River, which flows through Kozhikode and Malappuram Districts.

How many dams are there is this Chaliyar River basin other than some small weirs?

Blame it on dams..
Why ur doing annual maintenance of Idukki machines whn the Monsoon is active?

Smart QN.

But understand that Idukki is meeting Kerala's peak energy demand, its annual maintenance are done during monsoon and its all machine are needed in summer whn demand high, not in monsoon
