Abstract

The aim of this research was to analyze physical and chemical characteristics of low altitude lake of Jagadishpur Reservoir, a Ramsar site in central Nepal lies about 197 m altitude. The reservoir water was studied for three seasons (rainy, winter and summer) to compare the changes in the parameters. Water quality in reservoir was found less favorable to aquatic organisms, with low pH and transparency, low dissolved oxygen (DO), and high nutrient concentrations (Nitrogen). The reservoir was found eutrophic in nature by nitrogen concentration and transparency criteria. The findings created a database for present status of low land water reservoir of Nepal, which can be used for the management of lakes as well as to study the impact on water quality.This study provided useful information for decision makers aimed to the conservation and sustainable management of the reservoir.Int.

Highlights

Wetlands are interface between terrestrial and aquatic communities and the most productive ecosystem on the earth
They occur only where the water table is at or near the surface of the land or where the land is covered by shallow water. They have significant role in conservation of biodiversity and genetic resources. They play a great role in providing wildlife habitat, shelter for migratory birds, regulating water quality, flood control, production of organic material and conservation of rare and endangered species (Oli et al, 2013)
The amount of dissolved oxygen decreased with an increase in water temperature

Summary

Introduction

Wetlands are interface between terrestrial and aquatic communities and the most productive ecosystem on the earth. They occur only where the water table is at or near the surface of the land or where the land is covered by shallow water. They have significant role in conservation of biodiversity and genetic resources. Wetlands in Nepal are exclusively fresh water in nature. They occupy approximately 5% of the total area of the country mainly in the form of rivers, lakes, reservoirs, village ponds, paddy fields and marshes (HMG/N 1992). Most water bodies are contaminated due to incorporation of different pollutants (Pani and Mishra, 2005)
