The A-Z of Jakkur Lake

  1. 1. This book sheds out information about Jakkur Lake and its biodiversity, industries, sewage, etc. using STP (Space Type Pattern)
  2. 2. Authority The BDA (Bangalore Development Authority) was in charge of the restoration from 2008 to 2010. In October 2014, BDA handed over the lake to the BBMP.
  3. 3. Birds Thousands of herons, cormorants and pelicans are the common birds one can find in the lake. The migratory and regional birds co-exist here. Some of the birds travel upto 8000 kms at one stretch to arrive at Jakkur lake
  4. 4. Contamination The types of contamination that usually occur in the stagnant waters of a lake are: bacterial, asphyxiating, fertilising and toxic.
  5. 5. Drains There are three storm water drains which feed Jakkur lake from the surrounding areas like Yela- hanka, Agrahara and Shivanahalli.
  6. 6. Encroachment The lake has been encroached not within the fenc- ing but just metres outside with humans, vehicles, apartments and a massive layout.
  7. 7. Fish Limited fishing activity happens in the lake with the fishermen signing a contract with fisheries department and breeding only Rohu, Catla and Jalebi fish varieties.
  8. 8. Groundwater Since Jakkur lake is a manmade lake, the flow of groundwater will vary. It depends on the hydrau- lic potential in the ground and it will flow from higher to lower potential.
  9. 9. Hyacinth Water hyacinth is an aquatic weed. Hyacinths de- plete the amount of dissolved oxygen in the water due to which a lot of fish die.
  10. 10. Islands The man made islands serve as a shelter for the thousands of birds residing in Jakkur. These are also known as the twin islands
  11. 11. Jakkur The lake at Jakkur is manmade and 200 yrs old. Jakkur exists towards the North- Eastern out- skirts of Blore.
  12. 12. Kalyani The Kalyani was set up to immerse Ganesha idols on the day of Ganesh Chaturthi. It is separated from the lake by a net so that the flowers and debris can be collected.
  13. 13. Landfills The lake and its surroundings have often been treated as a dumping zone. Debris, construction materials and garbage have been dumped in the vicinity of the lake.
  14. 14. Man MadeWetlands The plant is currently able to let out 8 million litres of treated water into the man-made wetland that further purifies the water by a natural process before letting it enter the lake.
  15. 15. Nitrate Nitrate is a substance that develops naturally from organic waste. Nitrate itself can function as an indicator of sewage contamination.
  16. 16. Open well There are bore wells and beautiful old open wells that adorn Jakkur lake. The constant water inflow makes the water level in the well proportionate to that of the lake.
  17. 17. Periphery There are at least 50-70 apartments around the lake. Dry, dusty roads lead to the lake from the surrounding areas. There is a walking path and bunds on the inner boundary of the lake.
  18. 18. Quality As natural wetland systems in urban environ- ments are sensitive and exposed, water cleaned by this method can never be guaranteed to be pota- ble. The quality of the water depends upon the natural causes as well.
  19. 19. Restoration With the restoration work done by BDA, the lake was dewatered, desilted and fenced. Bunds, creation of three artificial islands, walk path, food court and a few other facilities were also taken care of.
  20. 20. STP A 10 MLD STP (Sewage Treatment Plant) has been set up by BWSSB at the lake site since 2004. The in-house lab of the STP checks the inlet and outlet water quality at STP level daily. The STP was installed to let only treated water into the lake.
  21. 21. TDS TDS (Total Dissolved Salts) is a measure of the combined content of all organic and inorganic substances contained in a liquid.The level of TDS is measured as a parameter to value the correct- ness of the nitrate levels obtained.
  22. 22. Urbanisation The number of vehicles plying in and out and emitting carbon monoxide for the lake to absorb is high. New complexes and residential colonies have also been constructed.
  23. 23. Viral Infections Viral infections that spread by water are SARS, hepatitis A, polio and polyomavirus infections. Diseases caused by water spread bacteria are typhoid, dysentry and other infections caused by salmonella bacteria.
  24. 24. Weed Jakkur lake was once choked with weeds and sewage. Deweeding and conservation activities have been in progress. The overgrowing partheni- um weeds were cleared manually.
  25. 25. Xylem As the hyacinth is a floating plant, the xylem has a major role to transport water upwards. The transpiration rates are higher . Hence, less oxygen is available for the aquatic life lying beneath.
  26. 26. Yelahanka Jakkur lake is the main lake in the chain of lakes comprising of the Yelahanka Lake Upstream and Rachenahalli Lake Downstream. The STP receives wastewater from about 12,500 households from surrounding areas like Yelahanka and Agrahara.
  27. 27. Zephyr The lake at anytime of the day has a calming breeze that gushes by. The swaying trees, smell of the fresh lake water and the wind make it an enriching experience.
