The Nigeen lake is the deepest and most attractive basin of Dal lake which has attracted foreign tourists because of its placid waters and calm environment. The lake water besides recreation is also being used for cultivation of vegetable and potable purposes. In the recent years huge settlements have come up around the Nigeen lake on all sides reaching to a population of more than twelve thousand souls in the immediate catchment, which excludes the boat population and floating population who live in about fifty house boats within the lake. Raw sewage entering the lake has enriched the freshwater of Nigeen to a large extent. Statistically, ANOVA test showed significant variation in transparency, pH, dissolved oxygen, calcium, nitrogen and phosphorus indicating clear variation between littoral and pelagic zones. The present paper is an attempt to assess its present water quality status and to record the chemical enrichment of the lake water over a period of time.

Abstract


The Nigeen lake is the deepest and most attractive basin of Dal lake which has attracted foreign tourists because of its placid waters and calm environment. The lake water besides recreation is also being used for cultivation of vegetable and potable purposes. In the recent years huge settlements have come up around the Nigeen lake on all sides reaching to a population of more than twelve thousand souls in the immediate catchment, which excludes the boat population and floating population who live in about fifty house boats within the lake. Raw sewage entering the lake has enriched the freshwater of Nigeen to a large extent. Statistically, ANOVA test showed significant variation in transparency, pH, dissolved oxygen, calcium, nitrogen and phosphorus indicating clear variation between littoral and pelagic zones. The present paper is an attempt to assess its present water quality status and to record the chemical enrichment of the lake water over a period of time.
