The purpose of this study is to make clear of the qualitative mechanism of eutrophication and pollution of water in Gamo lagoon: especially the relationship between the mechanism and the distribution of chlorinity and particulate matters in this lagoon. This paper consists of the following topics: 1. Changes of chlorinity, particulate matters and ignition loss in water with lapse of the time at each station. 2. The condition of water circulation expressed by changes of chlorinity at each station. 3. Flocculation of this lagoon expressed by the distribution of particulate matters. 4. The mechanism of eutrophication and pollution of this lagoon. From the results obtained, it was concluded that the lagoon water might be clearly distinguished from the sea water, the river water and the estulline water, and the water from the entrance to the middle part at the lagoon was easy of circulation, but the water of back part was difficult of it by reason that the lagoon water with increasing particulate matters by flocculation had been causing pollution by running out of dissolved oxygen at the bottom. Furthermore it is presumed that water flowing into the lagoon is free from dissolved and particulate matters by flocculation, namely the lagoon may have a function to ventilate water.
