We are faced with water quality problems at Lake Shinji. Therefore, in order to solve these problems, we are required to understand the mechanism controlling the environment in this lake. River Ohashi connects Lake Shinji with Lake Nakaumi, so that the water exchange between these two brackish lakes, makes the problem even more complex internally. In this study, we analyzed a one-year data set to understand the dependence of water quality, specifically the variation of salinity, in function of external forces like weather and atmosphere pressure. Also, from a detailed observation at Lake Shinji, Lake Nakaumi and Ohashi River from September 26th to October 25th, we concretise important water exchange attributes between Ohashi River and Lake Shinji.
