Abstract
Gulshan and Ramna Lake, prime green spots of Dhaka city are on the verge of extinction now. The objective of study was to evaluate the variation in water quality parameters in two distinct seasons. Water samples were collected along different points and analyzed for various physiochemical parameters during spring and winter. To explore the sources and reasons of pollution, the whole area in and around the lake was preliminarily surveyed. pH of all the samples of Gulshan and Ramna lake was within the ECR standard in both spring and winter. Gulshan lake samples were found more turbid and colored in spring than winter. Iron in water samples was within the range where 5 day BOD was found higher in both lakes. As Dhaka city is expanding day by day with the increasing rate of population, nowadays it has become a regular event that lake areas are used up by the land grabbers. As a result, the lakes are becoming narrower day by day. Wetlands of Dhaka city has been squeezed so that the pollution has become a great threat for the existence of aquatic lives. Poor lake water quality impacts the ecosystem and aesthetic features negatively.
