This paper presents the result of the survey on sediments in the Odomari and the Natsuse reservoirs with the tributary drainage basins consisting of plutonic rocks or effusive rocks. According to the survey of the impounded water in the Odomari reservoir, its values of the Secchi-disc readings were from 1.6m to 4.4m, its pH values from 5.7 to 7.2, its temperature values from 6.0℃ to 29.9℃, for August in 1954, and in the Natsuse reservoir, its values of the Secchi-disc readings were from 1.5m to 3.0m, its pH values from 4.6 to 5.8, its temperature values from 16.0℃ to 23.0℃, for September in 1956. Moreover, the pH and the temperature distributions of the Odomari reservoir show the thermoclines and the metalinmions, whereas such phenomenons are not clearly seen in the Natsuse reservoir.
