  7. 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
