Abstract

With the tremendous influx of people and consequent urban development, increased anthropogenic activities in the catchment, inflow of untreated sewage, nutrients and pesticides from urban and rural areas, the water quality of Upper Lake, Bhopal has deteriorated significantly. An attempt has been made to study various physico-chemical parameters, specifically nitrates and phosphates of five different sampling sites of Upper Lake and to study the effect of catchment area activities on these sites.

Highlights

  • IntroductionUpper Lake of Bhopal, arguably the oldest among the largest manmade lakes in central part of India, falls under this category

  • The construction of storage reservoirs is an age old Practice in India

  • The present study was conducted for analysis and interpretation of quality of water samples collected from five different stations of the Upper Lake, located at different catchment areas

Summary

Introduction

Upper Lake of Bhopal, arguably the oldest among the largest manmade lakes in central part of India, falls under this category. The study area selected was Upper Lake of Bhopal, Madhya Pradesh. It is the life line of Bhopal created by Raja Bhoj in eleventh century. The Upper Lake is located between latitude 23o12' - 23o16' N and longitude 77o18' - 77o23' E The Lake has an urban, semiurban and rural catchment area and its water quality is largely affected by various anthropogenic activities around the lake. Amongst the various chemical constituents present in the lake, nitrate and phosphate are two important constituents that immensely help in the growth of the plants. Water intended for human consumption should be “safe and wholesome” ie free from pathogenic activities and harmful chemicals, pleasant to taste and useable for domestic purpose (Parashar et al, 2006)
