This will definitely affect the quality of the lake's water and its future as a crucial water body in a congested metropolis. The tonnes of top soil which flow into the lake as a result of the quarrying activities in the area is highly damaging. This damage has already occurred, a rough estimate arrived at by certain persons indicate that the cost of excavating a cubic metre of the silt in the lake bed would be about Rs. The other problem plaguing the lake is that of excessive growth of weeds like Ipomea and Water hyacinth. These have choked a good portion of the lake, especially on the IIT side.
Lakes constitute an important component of freshwater resources.
They are distributed in different geographical regions in the country. Most of the lakes whether natural or man-made , are directly or indirectly associated with the river systems. There is an organic relations hip between the lakes and river systems. Lakes serve as an important life support system by helping in recharging of acquifers and regulating hydrological regimes. They also act as natural traps for sediments and nutrients thereby helping to regulate water quality and sedimentation of the river systems from the catchment area.
