The paper attempts to investigate lakes/ keres/tanks, in the Bangalore Metropolitan Area, as they are an important component of a much neglected urban landuse i.e. “Open Spaces”. Extensive studies have already been made on lake systems, their conservation, restoration and management. This study has been made on the relationship of lakes to urban open spaces and built form. Lake surrounds have been studied and analysed for compatibility of land uses. Planning regulations have been examined along with financial feasibility.

The methodology consists of   visual studies and observations of phenomena related to water bodies and   lake systems in urban areas. The following prominent lakes were identified for study: Bellandur, Varthur, Agara Kere, Ulsoor, Lalbagh, Yediyur, Kempambudhi, Sankey, Mattikere and Hebbal Lake.

The lakes are classified into two categories as Urban and Suburban Lakes, based on their location. Of the urban lakes, Ulsoor,   Sankey   and Yediyur   are the most used by the public. An extensive visual survey of the identified lakes was undertaken with reference to maps available. Over 700 digital photographs were exposed as a part of the study. Inferences and remedial measures were suggested based on the analysis of the above study, which looks at lakes as an essential part of the urban eco-system and prescribes their conservation, restoration and management strategies to ensure a healthy urban fabric.
