Preparing the lake for the monsoon

March and April are scorching months but that's also when we get our lake ready for the monsoon.  VMware volunteers came over on 31st March to help us.

In the past when the lake was largely dry with only little pools of water that shrank by the day, volunteers had to pick up plastic bags, stray slippers, bottles and the like from a much larger area. This year with most of the 10 acre lake bed under water, only the highest point was dry and piled with the alligator weed removed from the water. If left there, they would sprout with the first shower. Some of the quickly multiplying salvinia molesta were trapped in the trash boom waiting to be lifted out. We may hate the plant but the fresh Salvinia makes a good manure. It had to be mixed with the dry leaves heaped in rows. Further, we wanted some big boulders brought to the wetland.

Volunteers at work

Many tasks and many hands. From 9 a.m. to noon, the volunteers from VMware led by Guruprasad Cashikar slaved under the hot sun doing each one of these with great cheer even though sweat dripped from their faces. They finished all the chores assigned to them but there's still more to do.

More volunteers are welcome!  

The best laid plans ...

Just when we don't want a shower, it rains and how! Last week we'd requested BBMP to remove the Salvinia Molesta, growing in front of the slum side. It was prevented from spreading everywhere by the alligator weed, another invasive weed which, thankfully, spreads less profusely than the dreaded Salvinia. The contractor was supposed to begin work soon after Diwali. Yesterday at around 3 p.m., while we were inspecting the Salvinia infested area, it began to rain sending us scampering for cover to the Gazebo. We were joined by a few others and our volunteer teacher, Mr. Ramakrishna Rao shifted the class to the security cabin. His two students are preparing for the 12th board exam and cannot be disturbed on any account. 

The rain continued and our 12 foot long level marker which was a good foot or more above the water, submerged. Within an hour, the Salvinia side too went under water. Now there's just a thin strip of alligator weed acting as a barrier! Our plan to remove the Salvinia manually was well and truly scotched. Perhaps we should revise our plan and get the Salvinia weevil from Trichur! Not for nothing did poet Robert Burns say that the best laid schemes of mice and men/often go awry. 

The photos show how the water level increased after yesterday's shower, post the last major shower on 6th October.

Hope in many forms

The fire that raged through the lake on the 16th of March almost killed our spirit. By burning several of our trees, it had made a mockery of our effort to increase the green cover in the area. The sun's heat, rapidly evaporating the water in the lake, sapped our enthusiasm as well. Whatever little water was present was getting covered with the Salvinia Molesta. Our many efforts to mobilize skilled labour to remove the Salvinia were making no headway. Attempts to get more residents to strengthen our effort drew a blank as well and only our regular volunteers attended our recent assessment meeting. Despite all these, we couldn't throw up our hands in despair. Not yet at least. Not while our trees and shrubs are growing so well. Not while our resident birds are, well, still resident. 

We got our gardeners to water the plants every day buying a tanker load of water every three or four days (we still do not have a reliable water source at the lake) in the hope of reviving them and they did! The ground around the trees may be black and the few dried leaves cling obstinately to the branches but new leaves are sprouting!! Fresh, green and tiny but spelling hope and promise of a new beginning.

Two trees, the identity of which had puzzled us resolved the issue once and for all by flowering for the first time. The trumpet shaped yellow coloured flower tinged with honey brown is unmistakably Gmelina arborea (Shivani in Kannada, Gamhar in Hindi). The other is the Tabebuia rosea (Pink Trumpet Tree), and there are two of them growing tall in the corner near the encroachment, adjacent the main road from Brigade Millennium.

Today morning, birder Srinivas called excitedly to say that while passing by he'd spotted a Painted Stork in the lake. What? Despite the little water and the salvinia? This had to be seen to be believed. We rushed to the lake and what do you know? There was indeed one big Painted Stork foraging for fish! Giving him/her stiff competition were a large sized Egret (Intermediate?) and a Grey Heron.

The things that give us such great pleasure may seem trivial and small to others but may the lake continue to surprise and enthuse us all!

The weekend is here again!

Volunteers who attended last weekend's deweeding sessions at Puttenahalli Lake admit it was hard, but satisfying work. Though we had dissuaded children from "working", there were several who accompanied their parents and finally joined in.

Here is what some of the volunteers had to say, after putting in a good few hours last Sat/ Sun morning.

It was a great feeling to get down to the surface of the lake and  "de-weed." I had a feeling that Mother Nature was asking for a small assistance  from our side to help her bloom and extend "her healing effects of calmness" on us for the coming monsoon season..!

It was also a great place for making new friends from the neighbourhood who had just pitched in with their assistance during their regular morning walk. I was delighted  to observe  children ( 5  to 15 years) scraping away and transferring the sackful of weeds energetically.

Even though de-weeding the entire lake surface is a challenging task to be completed before the onset of monsoon, but I believe anything  is possible provided we have the drive and the passion for it.

Personally I'm committed to it as I would like to have the same experience which I had last year walking around the Puttenhalli Lake. The lake in its pristine beauty with the birds landing smoothly on the calm surface of water,  fish frolicking around on the surface, brought calmness to the mind and emphasised that nature was still beautiful as it always has been.

The only effort we humans have to put forward is to create space for nature to bloom in the current concrete jungle of our city life!

Shome Sengupta 

The men and women, boys and girls of our neighbourhood are taking small steps in protecting and nurturing the lake. Planting trees to prevent soil erosion. Weeding the waterbed to let the soil breathe. And the reason we feel so enthusiastic is that we can see our actions as firm steps towards rejuvenating the lake. in our mind, we can see the ripples of water this monsoon, and a safe haven for migratory birds in the winter.

Shana Gokul 

It was nice to see a good number of volunteers who despite their busy schedules decided to spend some time for deweeding the lake. The work in itself was not easy but all of them put in their full effort and managed to clear a substantial portion of the lake in few hours.

I am glad that my 10 year old son showed interest to join as a volunteer for deweeding the lake. It is exam time, still, in his enthusiasm to join us he did all his studies the previous day itself. I could make out his excitement on seeing big earthworms, rescuing fishes, was listening when one of the volunteer was explaining about the fish, though he was exhausted being in the sun, he enjoyed himself thoroughly and at the same time helped in whatever way he could. I am glad that I could take him to close to nature and experience it first-hand.

I am definitely coming next week with my son again and I wish more volunteers could join us in the next week's cleaning session.

Deweeding the Puttenahalli lake was a hands-on experience, rather unique and not given to all. We were a group of people on the lake bed, under the rising and heating sun uprooting the weed that was quietly killing the lake. I didn't know the others till afterwards but for those two hours or so we, one child of 6 years and the rest of us, adults worked in unison with determination and absolute love for our neighbourhood lake. I will go again next weekend and do my share to ensure that the killing weed is removed, that the fish have more room to swim, that sunlight falls on the water, that our lake thrives once again. 

Please join us again at Puttenahalli Lake this weekend - 

Saturday 16th March and Sunday 17th March 

7 a.m. to 10 a.m. 

Please bring a cap and drinking water for yourself. 

Report on the volunteering weekend at Puttenahalli Lake

Saturday, 9th March 2013

With some 20 volunteers responding to our call to remove the drying aquatic weed from the lake bed, it was a most satisfying morning today!

Their enthusiasm was infectious and several people stopped jogging/walking to see what they were doing, then joined them to remove the drying Salvinia Molesta. Working with a rake, a spade or simply scooping up the weed with bare hands, they filled plastic bags, formed a line on the slope, handed each bag over the grill where others waited to cart them away. The dry Salvinia can be used for mulching or composting. We have opted to compost them by laying them along the boundary fence.

Despite working hard for over two hours, only a patch of ground has been cleared. With more of you joining us tomorrow (and on subsequent weekends) we should be able to accomplish our mission of clearing the lake bed and getting it ready for the monsoon.

Another good morning at the lake today with some new volunteers joining us. 

Y/day's experienced hands were surprised to see fish in parts of the lake, below the weed. A few were dead but thankfully, most were alive. It was not possible to pull the weed out since the fish were coming with it so the kind souls made holes in the Salvinia for the fish to breathe. A couple of volunteers transferred the fish to the pools of water, carrying them in a bucket of water. It must have been a poignant moment for our volunteers renewed their effort to pull out more Salvinia and clean the ground. 

It was a hot morning but all of us felt the satisfaction of having done a good job. 

Dedicated work

Slow and steady

Heart felt thanks to all volunteers. We look forward to having you over next weekend. Do share your experience in this forum and with your family and friends and get them over as well!

Volunteers needed this weekend at Puttenahalli Lake

Work on the Diversion Channel is proceeding well and with a reasonably good monsoon this year we hope to divert lots more rain water into our Puttenahalli Lake. We may even see our wish fulfilled finally - the lake bed covered with water and not a bit of ground to be seen!

Now, when the water level is at its lowest, is the right time to remove the invasive weed Salvinia Molesta from the lakebed. Will you help us get the lake ready for the monsoon? Help us get rid of the weed and bring the birds back to our lake? Help us get the lake ready for April showers?

Please volunteer your time and effort for just three hours this weekend!!

Dates: Sat. 9th and Sun. 10th March.
Time: 7 to 10 a.m.
Age: 16 years and above. There's no risk involved but we would like to focus and not have to supervise children. :-)

Volunteers will be required to wear comfortable shoes (not open sandals) and a hat. Gloves optional.
Email confirmation <puttenahalli.lake@gmail.com> will be very welcome but you can always drop in unannounced, pick up a rake and scoop out the weed this weekend!

Birds, birds!

Nirupama Sriram who lives in the JP Nagar 7th Phase area, made full use of the two day bandh (on 20th-21st Feb 2013) by spending time at Puttenahalli Lake and taking photographs of the birds. Her discerning eyes have captured them so beautifully!

The Wood Sandpiper and Yellow Wagtail are both migratory. In fact, the Yellow Wagtail is one of the early winter visitors and is likely to begin its return migration soon since it is becoming pretty hot here.

It is easy to confuse between the Mynah and the Rosy Starling. The closeups show the difference - the starling has a rose coloured body. It is also migratory and spends winters in India.

The other birds are residents but no less important to us! The Pond Heron looks like a silver statue in the backdrop of the Salvinia Molesta! We hope to get the weed removed fairly soon and make the lake attractive to many more birds.

Please walk past the lake on 13th to reach MLR

Please use "Doosra" as an excuse to walk through the lake and reach MLR Convention Centre. You'll see that the water level is low. It is covered with Salvinia Molesta. BUT don't miss the birds. It is likely that you can id the birds yourself but just in case you want to know - Purple Moor Hens are plenty. So also pond herons. The Purple Heron (we have a pair) take a little spotting. They are big but sit so still while waiting for prey, you may not even notice them. The Ashy Prinias are plenty too but they are small, and not easy to spot either unless they fly out into the open. They are also called warblers and you may hear their cheerful "tweet ... tweet." Other birds to look out for are: White breasted Kingfishers, White breasted Waterhens, Bronze winged Jacanas, Tailor birds, sun birds and mynahs. All these are our resident birds - Salvinia or no Salvinia. Bless them!

Going from South City, please take the walking track on the left. (The pathway on the slum side has been dug up further ahead for the BWSSB to lay a bigger Under Ground Drainage pipeline.) As you walk along the track, look at the assorted trees. The smaller ones near the turning were planted only a few months ago. Those towards the Gazebo were planted from July 2010. Some are very tall and some have begun flowering as well. As part of the 3rd phase, the BBMP has laid an irrigation pipeline all along the fence. To prevent miscreants from ripping it up, it is laid underground. However, you will see a short length of blue - grey plastic occasionally jutting out of the ground. A valve will be fixed to these ends. Once water connection is given, we will fix a hose pipe and draw water from these points. When it becomes operational, we intend to plant shrubs between two trees within the inner grill. The shrubs will serve the dual purpose of attracting butterflies while deterring trespassers from crossing the fence.

As you come out of the lake premises, the huge concrete pipe lengths outside are for the diversion channel to harvest rain water from Brigade Millennium (BM) road into the lake. The contractor wanted to begin work last week. We requested him to do so after the play on Sunday (so that you can walk through to reach MLR). Our lake is one of the very few in the city to be free of sewage inflow, hence the low water level. With the new diversion channel in place, we hope more rain water will enter the lake. Well before monsoon, the contractor will remove the Salvinia from the surface of the water. More birds will then return to the lake making it once again a little bird sanctuary in our neighbourhood! 

After this walk or after seeing the play, if you feel peckish please visit the MLR Snacks counter. Kai Ruchi will be serving Hot Bhajji, chaats, hot and cold beverages at reasonable rates.

On your way back from MLR, take another good look around the lake and its premises. Together with the BBMP we are slowly inching towards transforming the lake with lots of clean water, birds and butterflies. We need your support to sustain our work. Come to the lake as often as you want, help us effect the transformation!

Oh yes! If you didn't get donor passes in advance, it doesn't matter. You can get them at the venue. Two shows: 3.30 and 7 p.m. Each pass goes to nurturing the lake and remember, you can claim IT exemption u/s 80G. Go for it! See Doosra! Help our lake!

Those from BM side (who can reach MLR without crossing the lake) can still take a walk to the lake before coming back to MLR!

Exciting times for our lake!

The Salvinia Molesta covering the surface of our little Puttenahalli Lake has not deterred all the birds! Our regulars, the Purple Swamphens, Purple Heron, Pond Herons among others had refused to leave the lake even though the invasive aquatic fern was spreading on the water. They have now been joined by a Grey Heron, a couple of Cormorants and Kingfishers! The Kingfisher especially is good news. It means that the water below the Salvinia is still fresh and alive. These were just a few of the birds we spotted in the midst of what seems like a 1001 tasks we have to do at the lake. Not that we are complaining about the tasks since we mooted them ourselves. :-)

These are exciting times for our lake. On our request the BBMP has issued a work order to execute a number of initiatives which will infuse new life into the lake.

The first of these is the Diversion Channel to draw surface rain water from the Brigade Millennium avenue road into the lake. The Channel will be laid from the BM arch to the lake. According to a Total Station survey done in Sept 2011 to assess the feasibility of diverting this water, the quantum entering through this new feeder channel will be quite substantial. The first of the massive (45 inches inner diameter) pipes have been unloaded and will be kept in place soon. The channel will be put to test during the next monsoon.

Pipes for the Diversion Channel

The contractor has also been entrusted with de-weeding the lake. Getting rid of the Salvinia Molesta is not going to be easy. It has to be removed manually from the water, dried and then disposed appropriately. The contractor's men are clearing another lake and once that is done, they will start de-weeding ours. We had only heard of Salvinia Molesta but not seen it at close quarters before. It is a beautiful aquatic fern, so decorative that it is sometimes used in home aquariums. However, the smallest fragment of the fern can double its dry weight in about two days, spread like a blanket over large water bodies and is known to have killed lakes across the world. We have learned our lesson with Salvinia Molesta. Any time in future that we spot a piece in our lake, we will pluck it out of the water. We have geared ourselves very well for this with a variety of rakes to snatch out the smallest bit of this hateful fern.

Gardeners at work clearing the slopes

While waiting for the Diversion Channel pipes to arrive, the contractor got his men to start digging a trench and laying an Irrigation Pipeline all around the lake to facilitate watering the plants. At present we get water tankers to fill the tanks and the gardeners use the wheel barrow to ferry filled buckets to water our 320 trees, many shrubs and other plants. A laborious task to say the least not to mention an expensive one. The bore wells around the lake are recharged thanks to the lake but the well operators do not reduce their charge one bit! The Irrigation Pipeline will enable us to plant two more rows of trees on the slope, countless small flowering plants between trees on the embankment, shrubs, creepers, climbers and what have you to give ourselves a green nice cover in the neighbourhood.

Irrigation Pipeline trenches

If you think these are just pipe dreams, please visit the lake and see the work happening. Perhaps you can supervise the workers and relieve us of that chore? Perhaps you may like to join us in our effort to maintain, or rather, transform a lake with people power?
