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

 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
