Recently, the environment of river is regarded as an important factor for river management. The river management law was altered in 1999. The new river law indicates that water quality of river is an important factor for river management. The problem of water pollution in the Lake Kahokugata is getting worse in Ishikawa prefecture. A prediction of water quality in the Lake Kahokugata needs to understand characteristics of water quality alternation of rivers that flows into Lake kahokugata. The Tsubata River is one of the large river which flows into Lake Kahokugata. In this study, a field observation of water quality was carried out over 3 years(2003-2005) in the Tsubata River. This study indicate characteristics of water quality flux alternation about every ion, suspended solid(SS), Total Nitrogen(T-N) and Total phosphorus(T-P) at Tsubatagawa Bridge point. Highlyconcentrative T-P and T-N is detected at Tsubatagawa Bridge point compared with the concentration of T-P and T-N detected at Suminoe Bridge point (1.5km below Tsubatagawa Bridge point).
