â�?�?COMPARISON OF THE PHYSICOCHEMICAL PARAMETERS OF TWO LAKES AT LODRA AND SOJA UNDER BIOTIC STRESSâ�?

A. C. Patel, Dr. R. S. Pate

The presented study deals with comparative study of the periodic and aperiodic variations of Physicochemical status of two lakes belongs of Lodra Lake and Soja Lake of Gandhinagar District, Gujarat India. Lodra Lake is situated on the High-way to Gandhinagar-Vijapur, of Gujarat state.and Soja Lake is situated on the Highway to Kalol-Mansa, of Gujarat state. Lodra Lake is natural freshwater body having 6.18 hectors area & an irregular in shape. Lodra Lake is located between 72042’46’’E to 72043’23’’E latitude and 23027’06’’N to 23028’01’’N longitude. It is oldest lake of Mansa taluka known as Dudheshwar Mahadev Talav, constructed before year 1910. Soja lake is located between 72034’58’’E to 72035’05’’E latitude and 23021’47’’N to 23022’49’’N Longitude. Both lake are oldest and natural freshwater body .Water is essential for living organisms especially like Flora and Fauna, observed through various field trips. A comparative study of the periodic and a periodic variations of Physicochemical status of two lakes were studied in year January to June 2011. Both the lakes are biotically affected by various anthropogenic activities. In the present study water characteristics of two lakes have been compared the water quality. Different Parameters analyzed like pH, Fluoride, COD, BOD, Chloride, Alkalinity, Total Hardness, Calcium, Calcium Hardness, Magnesium, Magnesium Hardness, DO, EC and TDS. The result indicates that the both lakes are in polluted condition.
