Abstract

Upper Lake, designated as a Ramsar site in Bhopal, India, plays a major role in sustaining ecological balance and ensuring water security in the region. This study provides an extensive spatiotemporal analysis of the lake's water quality by assessing essential physiochemical parameters and calculating the Trophic State Index (TSI) through systematic in-situ observations. Field data were collected from spatially distributed sampling sites during the pre- and post-monsoon seasons of 2022. Key water quality indicators, including Secchi disk transparency (SDT), dissolved oxygen (DO), pH, water surface temperature (WST), total alkalinity, turbidity, TDS, conductivity, and total hardness, were quantified and subjected to statistical evaluation. Various spatial interpolation techniques were employed, and the most effective one was selected to create two-dimensional images of lake water quality. The TSI, derived using Carlson’s method, indicated that the northeastern side of the lake consistently experienced eutrophic to hypereutrophic conditions. During the post-monsoon period, observations indicate that the western side exhibits hypereutrophic conditions in the lake water. The results indicated significant spatiotemporal fluctuations in water quality parameters, with anthropogenic activities and climatic factors influencing trophic dynamics. This study highlights the necessity for sustainable management strategies to reduce eutrophication risks and to maintain the ecological integrity of lakes.
