The site is situated at the lowest point within the adjoining colonies. In the surrounding areas, residential blocks are topographically higher. Earlier, all the rainwater in the area used to get collected into the lake, preventing flooding on colony roads and replenishing the groundwater table.
After the lake was closed down, storm drains on the roads were channeled to exit into the Yamuna river. However, every year the storm drains get filled with plastic waste and silt, which blocks the drains, and then it requires excavations and renovations at regular intervals.
Wonderful..so so important. Just to add to it, please do Riperian plantation i.e., along the edge of the bank at multi strata level. Mix it all up like the birds would have planted it: Starting from reeds & aquatic plants, to herbs & shrubs, trees like mulberries & willows & other understorey, mid canopy & overstorey plants. Also add bamboo, banana papaya etc. As Delhi climate is hot & humid, this will drastically minimize evaporation from solar radiation & wind, & will help sustain the water throughout the year. Hoping to see more such projects by NDNS in the future. Amazing work!!
Add some other features like dead wood on the edges & within the waterbody, for accelerating habitat for frogs, fishes, birds, tortoises etc….
It’s really a grt initiative by ndns.Wld love to visit the lake area( after the 2nd wave) and experience it personally.
I think such an effective action of lake revival in the midst of our city life is to be appreciated deeply.
