Abstract

Anthropological activities play a crucial role in physical as well as biological environs of the lake. Discharge of sewage into the lake is a threat to its quality and hygiene. In this study, it is observed that Dal lake is receiving discharges of wastewater from the domestic and tourism industry. Sewage has consisted of nutrients like nitrogen, phosphates that are responsible for the growth of algal bloom/ aquatic vascular plants. That unwanted growth of aquatic plants and sprawling all over the lake is a significant concern about quality deterioration and aesthetic beauty. In this study, an attempt has been made to assess the changes in and around the Dal lake, Srinagar based on satellite images from 1975-2019. Based on this, measures are suggested to control the anthropological discharges as well as in-situ and ex-situ lake treatment since the lake has international importance and source of water supply to the city.
