Powai Lake walk in the rain! Elsie Gabriel



Powai Lake walk in the rain! 

Powai lake in Mumbai.




My daily evening walks drew me to the Powai lake once again today. My weekly haunt. I took a quick call to visit the periphery of the lake borders and extended my footsteps towards where the waterfall beckoned. With each step closer to the Ambedkar Garden, I could hear gushing sounds of water, the sound of rain going on an overdrive flow. The sound of nature. The healing sound of blessings from heaven. Rain does do something to you. Rain not only drenches you, it controls you, takes over you and when you give in to a beautiful walk in the rain, specially without an umbrella or a care in the world, you know that it is Nature, nature becoming one with you. Rain involves you, it revives you, it wakes you up and most of all quenches your thirst for nature in all its being.

I would like to share with you that it is said that the Powai lake was built by the British, in the year 1799 A.D.  Powai is situated in the North East of Mumbai and is gifted with the Powai lake. The Powai dam and reservoir made in 1889,is located at the Dr.Ambedkar Garden, popularly known as the BMC Powai Garden. Having conducted over 200 nature walks in the garden I know it like the back of my hand, but every time I step into its labyrinths I am offered new findings.
 
Come take a nature walk with me in Powai.


Old nature trail paths give way to new....


The garden is maintained by BMC and is under 'S' ward, although the Powai Lake comes under the Hydraulic department of the North East zone and under the care of the Additional Municipal Commissioner of Projects. I have spent hours fishing here and exploring the jungles much before it got its present manicured lawns and benches.

The Powai lake ecosystem is teeming with life and it cannot be neglected! Investigating the physical, chemical and biological relationships that take place in and around the Powai Lake is important because they are tied to the environment surrounding them; investigation of the floodplains, drainage basins and the atmosphere is vital. Every week I study the eutrophication of this water body. Eutrophication is a natural process that has caused this lake to age. However, human-caused, accelerated eutrophication has occurred more rapidly, and caused problems in the affected water body. Urban and industrial runoff also contribute to eutrophication but here in Powai we have garbage, silt, mountain mud, storm water drains over flowing, specially during the heavy rains. You have to walk in the rain and literally watch this for your self, right before your eyes.
Rich nutrient input stimulates growth of duck weed, water hyacinths, algae which change the lake as their populations increase. This is particularly the case when they undergo population explosions, basically as the chemicals like phosphates and nitrates..example-fertilizers make the lake more productive. That is why you see more green in the lake than you see water.

When the carpet of thick green stops sun light penetrating into the water, this decreases the productivity of plants living in the deeper waters. The water becomes depleted in oxygen. When the abundant algae die and decompose, much oxygen is consumed by those decomposers.  Lowered oxygen results in the death of fish that need high levels of dissolved oxygen .All this happens below deep beneath the lake that you pass by everyday in your bus or car.
The powia lake tries to fight it off as much as it can but starts to stagnate each year when the contractor is laid off. There is an organic relationship between the lakes and river systems. For the fifteens years that I have lived in Powai I believe there is a bond between the hills and the lake, and watching the space between them tighten pains me.

There are many bird species inside the Powai Lake ,some of them are Common & White  throated Kingfishers, Herons, small blue Kingfishers, both Phesant tailed and Bronze winged Jacanas . Around 30 odd bird species visit the lake during  December to May. The frequently seen birds in this period are Black winged stilts, Jacanas, coots, spot billed ducks, little cormorant,  little grebe, glossy ibis, white ibis, whiskered terns,  yellow wagtail, pied mayna, osprey and many more. Oriental Magpie Robins, Coppersmith Barbets and Parakeets, Bulbuls, Common Tailorbirds are among others. There species of fish like the Rahu,Katla,Catfish and Mrigal as well various species of snails, crocodiles and turtles too all part of the habitat! Duck weed, water lilies and water hyacinths are some plants of the lake. Conservation has to be stressed upon where ultimately there will exist a balance between development and Nature! Powai lake and it’s habitat should be treasured ,where in a city filled with concrete jungles can one find a lake and rich bio-diversity?
Come visit the Powai lake in all its glory during the monsoons. Take back a connection with nature which will stay with you till eternity…..

 
Give credit where it is due..good job BMC-Wet and Dry bins..use them wisely...found these outside the garden....
