Vellayani Lake - Revisiting the Past

Earlier, in 1953, the lake was used for growing lotus flowers for Padmanabha Swamy temple. When the 'Grow more Food' programme was launched by the government in 1950's, large tracts of land were reclaimed for cultivation.

The lake is de-watered twice in a year for paddy cultivation by farmers. There is scarcity of water in neighbouring panchayats of Vellayani and Thiruvananthapuram and water reaches the population residing here by tankers. These panchayats include Thiruvallam, Kalliyoor, Nemom, Venganoor and Kovalam.

Many ways of conservation of the lake have been suggested by various environmental organizations and local populace. Some of these methods have been mentioned below -
  • Dewatering the lake must be curbed at the earliest as it endangers the reservoir. Several drinking water projects that cater to water requirements of neighbouring Panchayats also are threatened.
  • For preservation and conservation, the Vellayani lake must be handed over to Public Health Engineering Department.
  • Measures must be initiated to check pollution of the water body by chemical fertilizers, solid waste, sewerage and pesticides.
  • Fish farming in Vellayani lake must be controlled for improving water quality.
  • Anti-pollution sign board near the lake will go a long way to create awareness.
  • Too much construction work around the lake has led to ecological disturbance and pollution in the area.
