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

MI Tank Reg. No. is based on districts (for eg. Magadi district is nowBangalore Urban and now No. are mention two lakes) not directlyrepresent the location of waterbody (Village, Taluk, etc.)

Feeder tanks (Gokatte & Kunte) were not considered duringNumbering

EMPRI has developed the unique ID codes for all the water bodies byfollowing the ISO Standard
