Achankulam Lake UPSC NOTE

 Why in news

  • Achankulam, one of the tanks in the Noyyal River system that supports a large number of avifauna and other lesser-known species, faces a threat from water hyacinths destroying the wetland’s ecosystem.

  • The invasive plant has completely occupied the south side of the waterbody, known as a gathering spot for large numbers of water birds, including rare migratory ones.

    Water hyacinth

  • The water hyacinth (Eichhornia crassipes) is a beautiful but invasive aquatic plant native to tropical and subtropical South America

  • It is known for its glossy green leaves, attractive purple flowers, and rapid growth rate.

  • Water hyacinths can reproduce vegetatively at a very fast rate, doubling their population size in as little as two weeks. 

  • This rapid growth can quickly form dense mats that cover the water surface, blocking sunlight and hindering the growth of other aquatic plants.

  • When water hyacinths die and decompose, they use up oxygen in the water

  • This can lead to oxygen depletion, which can harm fish and other aquatic life.

Achankulam Lake

  • The Achankulam Lake you are referring to is located near Neelambur village in Sulur Taluk, on the outskirts of Coimbatore city, Tamil Nadu.

  • It is one of the tanks of the Noyyal river basin, along with 24 lakes in and around Coimbatore.
