Many major lakes in Bengaluru, India have dried-up due to inconsistency in preservation of feeder tanks such as Gokatte (extend is 1-3 acres) and Kunte (extend is below an acre). The existing waterbody database maintained by the authorities is not comprehensive, as there are no details about the small waterbodies (feeder tanks) and waterbodies vanished (non-existing) due to developmental activities or urbanization. So a pilot study was conducted in the Western Bengaluru (78 km2), which encompass the NadaPrabhu Kempegowda (NPK) and Sir M. Visveswaraiah (SMV) Layouts to inventories the small and non-existing waterbodies through the village maps, Toposheet, Satellite imageries, etc., which also physically verified. The 117 waterbodies including 34 Kere, 37 Gokatte and 46 Kunte were inventorised and 36 waterbodies were found disappeared. Waterbodies (existing and non-existing) were village specifically coded by using the alphanumeric ISO 3166 coding system to rectify the confusion between the un-named waterbodies, same name waterbodies and non-existing waterbodies. Inventory and coding of all the waterbodies in Bengaluru shall provide good database for Lake Development Authority and other stakeholders in taking decision on the rejuvenation, eviction of encroachment and for sustainable management of lakes.
