The document summarizes a study conducted by the Centre for Lake Conservation and Environmental Management & Policy Research Institute (EMPRI) on the lakes in and around Bangalore. The study involved collecting comprehensive data on 117 water bodies, including their morphology, hydrology, land use, water quality, biodiversity, and threats. Issues like pollution, encroachment, excavation and religious activities impacting the lakes were documented. Based on the findings, strategies for conserving the lakes and a water management plan were proposed. The study helped increase awareness, remove encroachments from some lakes, and issue notices to polluting units.

3. Why this Study?
 Lack of comprehensive data on water bodies like
Lakes, Gokattes & Kuntes
 Water bodies are under severe threat due to rapid
urbanisation/ industrialisation
 Bangalore is already facing acute water scarcity and
certainly increase by leaps and bounds
 Finding possible ways for conserving these water
bodies and to enhance their ecological and economical
values

7. Coding of water bodies
 One water body may have different names and most of them are
called as Hosakere
 MI Tank Reg. No. is based on districts (for eg. Magadi district is now
Bangalore Urban and now No. are mention two lakes) not directly
represent the location of waterbody (Village, Taluk, etc.)
 Feeder tanks (Gokatte & Kunte) were not considered during
Numbering
 EMPRI has developed the unique ID codes for all the water bodies by
following the ISO Standard
Eg. Bhimanakuppe Hosakere: BgUBSKGbmk_kr01-038
Gokatte gk ku Kunte
BgU BS KG bmk kr 01 038 EMPRI Code No.
District Name Hobli
Taluk Name Name
Bang. Urban
Bang.
Village Name
Kere Waterbody No. in
Kengeri
South Bhimnakuppe Village
