Yele Mallappa Shetty Lake is one of the largest lakes in Bangalore, located on the eastern side of the city, outside of KR Puram. It is an artificial water reservoir constructed in early 1900s.[2] The lake is spread over 490 acres (198.3 ha).[3]
Geography
The lake is located in North-East Bangalore, near Whitefield. The 260 acre Yele Mallappa Shetty lake is one of the largest lakes in Bangalore. The lake has the Old Madras Road passing through it.[4]
History
Yele Mallappa Shetty Lake derives its name from a leading philanthropist of 1900s by the name of
Due to rapid growth of Bangalore urban area, Yele Mallappa Shetty Lake has been getting encroached over the time. The multi-storey apartments in its watershed region, which are constantly feeding stormwater drains completely but are also letting untreated sewage directly into it. Even industries from surrounding areas started dumping their waste into the lake.[6][7]
In December 2017 a sewage treatment plant at Seegehalli was inaugurated to help treat 15,000,000 litres (4,000,000 US gal) of sewage water per day (MLD) generated at
Water quality
In 2015 a study on water quality at the lake was conducted. With regard to the lakes physico-chemical characteristics, observations were made three times in a year representing three different seasons. The samples were collected from three different places of the lake.[9]
Following are the observations from the report:
- Physico-chemical analysis: Lake water contains different types of floating, dissolved, suspended and microbiological as well as bacteriological impurities
- Temperature: Neither too high nor too low
- pH: Normal range
- Electrical Conductivity (EC): Higher side; indicating higher levels of alkalinity
- Dissolved oxygen (DO): Lower than the standard
- Bio-chemical Oxygen Demand (BOD): Moderate
- Chemical oxygen demand (COD): Exceeded the limit in most of the samples. It clearly indicates the presence of high levels of dissolved contaminants
- Hardness: Very high
- Alkalinity: Higher side
- Sodium: Concentration of sodium was found to be lower
- Potassium: The concentration of potassium was high
- Phosphate: Comparatively high amount of phosphate was recorded due to the discharge of municipality sewage and dumping of domestic waste into the lakes
- Nitrate: Relatively larger amount of nitrate was found
Flora and fauna
The lake is a biological hotspot for migratory birds, some of the usually spotted birds are
