Chikkabettahalli lake is facing survival crisis due to shrinkage of water spread area (encroachment, dumping of building debris) with the sustained inflow of untreated sewage. Nutrient concentration in Chikkabettahalli lake water is high, evident from physico- chemical analysis, the presence of fully covered varied macrophyte species and pollution tolerant algal species. This has resulted in the obstruction of light penetration and lower dissolved oxygen (DO) values. Deliberate dumping of building debris and solid waste have reduced the spatial extent of the lake. Unabated dumping of solid waste, building debris and sustained inflow of contaminants (sewage, etc.) further highlights the apathy of local administration in the conservation of natural resources. Agony of  the lake is evident from encroachments, dumping of solid and liquid waste, which highlights the nexus among polluters, land mafia and decision  makers.
