The present study assesses the physicochemical characteristics of water, soil quality, biodiversity components, and flood impacts in the Upper Krishna Basin. Water samples were analyzed following standard APHA methods, focusing on parameters such as pH, temperature, dissolved oxygen (DO), total dissolved solids (TDS), total solids (TS), and nitrates. Most parameters were within permissible limits, though spatial variations indicate anthropogenic influence. The study also documents fish diversity, the presence of non-native species, and the need for systematic monitoring of Crocodylus palustris populations.
