WATER QUALITY STATUS OF AN URBAN LAKE, DAL IN KASHMIR HIMALAYA, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

Accurate and timely information about aquatic ecosystems and their changes through time is becoming increasingly crucial, particularly in metropolitan settings. The current study looked at the water quality of Dal, a city lake in Kashmir Valley. The indicators of water quality were measured using the American Public Health Administration’s standard approach. The lake is extensively polluted with organic and inorganic wastes of human origin, according to physico-chemical and biological analyses of surface water quality. The water quality data from Dal Lake was compared to the World Health Organization’s (WHO) drinking water regulations, and it was discovered that several metrics like pH, alkalinity, and coliform had exceeded the acceptable limits. The water quality index (WQI) of the lake ranged from 185.8 in the winter to 17217.7 in the summer, indicating that the lake’s waters are unfit for consumption. Anthropogenic activities such as dumping raw faeces from houseboats, untreated sewage from settlements, and fertiliser runoff from catchment areas have all been identified as major contributors to nutrient enrichment and water quality degradation in this significant urban lake. As a result, to protect the health of this significant aquatic ecosystem, a constant programme of water quality monitoring over the lake surface is required to maintain the lake’s health.
