“…The seasonal pH concentration was not significant as the waters were well buffered. This is in conformity with Zutshi et al (1980). Dissolved oxygen is one of the most important abiotic factors influencing an aquatic environment.…”

Introduction: The impacts of land use/land cover (LULC) pattern on surface components of water are less well recognized, particularly in the Kashmir Himalaya. The paper highlights the relationship between LULC and water chemistry for Wular Lake in Kashmir Himalaya. Methods: We used Indian Remote Sensing satellite (IRS) P6 using LISS III sensor with a spatial resolution of 23.5 m for various LULC categories. ERDAS IMAGINE 9.0 and ArcGIS 9.3 were used to generate the LULC map. Water parameters like pH and temperature were measured in the field, while parameters like dissolved oxygen, free carbon dioxide, chloride, alkalinity nitrogen and phosphorus values were determined by APHA (Standard Methods for Examination of Water and Wastewater, 1998).Results: The present study provides us the information about the proportion of different land cover categories and their correlation with some limnological parameters of Wular Lake. Among the various physicochemical parameters, low dissolved oxygen (DO) was observed in the LULC class which has the highest percentage of agricultural land (47.04%; r = 0.688 P < 0.05) followed by horticultural land (19.10%; r = 0.554; P < 0.01) in its catchment. The catchment area with greater percentage of agricultural fields drains maximum fertilizers in the lake, resulting in growth of microorganisms that deplete the dissolved oxygen content in the water body. Conclusions: Pearson matrix predicts that agricultural land, built up, horticultural land and wasteland seem to be the foremost factors responsible for the deterioration of the water quality of the lake. Careful planning of land use is needed to bring significant reductions in nutrient exports from agriculture through various tributaries, in order to restore and maintain water quality of the lake. If this trend of agriculturization manifestation continues unabated, it will be difficult to restore the lake water quality and to subsequently correct ecological manifestation of eutrophication through which the lake is undergoing at present.

“…It might be due to the high silt content of the water carried down into the lake by the feeder rivers and streams from the catchment areas. Such similar results were reported by Zutshi et al, (1980). Chloride concentration was found maximum during rainy season in all the six sites and on the contrary it was low during winter season.…”

“…However Na concentration was low (8.46 mg/l) at S3 during autumn and was 21.24 mg/l at S1 during spring. Among these Ca is the most dominant cation which is attributed to the predominance of lime rich rocks in the catchment area [20].…”

Seasonal variation in surface water quality of Dal Lake was assessed using multivariate statistical techniques. Water quality data collected from 4 sampling sites during 4 seasons was analysed for 13 parameters. Significant variation (p<0.05) in temperature, pH, EC, Ca, Mg, Na, K, DO, BOD 5 , COD, PO 4 -P, NH 4 -N and NO 3 -N of sampling sites during different seasons was observed. Cluster analysis grouped 4 sampling sites during 4 seasons into three clusters of similar water quality as relatively less polluted (LP), medium polluted (MP) and highly polluted (HP) sites. The principal component analysis/factor analysis applied to extract and recognize the factors responsible for water quality variations in four seasons of the year resulted in three principal components for each season accounting for 75.78%, 83.25%, 87.33% and 78.96% of total variance for winter, spring, summer and autumn seasons respectively. Parameters like NH 4 -N, NO 3 -N, BOD 5 and COD have strong positive loading whereas temperature and dissolved oxygen has strong negative loading. Thus, from the principal component/factor analysis it is clear that the domestic wastewaters, agricultural runoff and catchment geology play significant role in water quality variations in the Dal Lake for all the four seasons.
