Trophic status of Chatri Lake in the vicinity of Amravati city.

Chatri lake is situated a bit away from the busy city. This lake is famous by the name Chatri Talaw. This lake was once used for drinking water purpose. Since 'Upper Wardha Project' came into existence the lake water is not used for drinking purpose. Site is such that it can otherwise be developed as an ecological spot and will be a place of attraction for the people. The present situation is such that, the lake is very fastly receding and becomes shallow due to heavy sedimentation. It appeared from our observations that low sodium and potassium content and reduction of photic zone due to high turbidity resulted in low phytoplankton density in the lake. Thus lake is oligotrophic in nature.
