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

Accurate and timely information characterising aquatic ecosystems and their changes through time is becoming increasingly crucial, particularly in metropolitan settings. The current study looked at the water quality of an urban lake in Kashmir Valley called Dal. The criteria of water quality were assessed using the American Public Health Administration’s standard approach. Surface water quality research found that the lake is extensively polluted with organic and inorganic pollutants of human origin. The water quality data pertaining to various physio-chemical and biological parameters of Dal Lake were compared to World Health Organization (WHO) drinking standards, and it was discovered that several parameters such as pH, alkalinity, and coliform had exceeded the desired limits. The lake’s water quality index (WQI) ranged from 185.8 in winter to a maximum of 17217.7 in summer, indicating that the lake’s waters are unfit for consumption. Overall, anthropogenic activities such as dumping raw faecal matter from houseboats, untreated sewage from settlements, and fertiliser runoff from watershed areas have been identified as the primary causes of nutrient enrichment and water quality degradation in this significant urban lake. As a result, a continual programme of water quality monitoring over the lake surface is required to ensure the health of this essential aquatic environment.
