Summary Introduction

Introduction: Oligotrophic lakes are lakes having abundant oxygen in water. This lake is the lake of low algal production, low nutrient content as like with high drinking water quality. Eutrophic lakes are the high nutrient water bodies with abundance of biological productivity. Due to high amount of nutrients, especially nitrogen and phosphorus,these support the increasing growth of aquatic plants. The excess algal growth suppresses the oxygen content in the water that causes ultimate death of fish due to respiration by algae and bottom living bacteria.
