On the Spatial Structure of Thermal Stratification and Water Quality Conditions in Lake Onogawa

Abstract

This paper describes thermal stratification and distribution of water quality conditions in lake Onogawa. The water quality of 8 items was tested, Water Depth, Water Temperature, Turbidity, Electric Conductivity, potential of Hydrogen, Dissolved Oxygen, Oxidation-Reduction Potential and 665nm absorption. Measurment through all the area of the Lake were taken three times in thermal stratification season.
As the results of these observations, the spatial quality conditions are suggested.
