The study on diversity of phytoplankton and water quality as the physical and chemical properties in Mae Nage Somboonchol Dam, Mae Taeng District, Chiang Mai Province were investigated 3 times a year, on June and September 2014 and February 2015, At deepest points reservoirs, the samples were taken every 5 meter in depth as 0, 5, 10, 15, 20, 25, 30 and 35 maters under the surface. All phytoplankton sample were classified in to 5 Division, 54 species were The dominant species were Spondylosium sp.1, Staurastrum smithii Teiling, Tetraedran incus (Teiling) G.M. Smith , Staurastrum sp.1 and Oocystis sp.1
The water quality parameter studied were shown that the depth of reservoir were impact to the changes of phytoplankton distributions due to the differences of physical and chemical. The using AARL – Physical and Chemical Score to assess the water quality was classified to Mesotrophic – eutrophic status. However, the overall water quality were classified to the mesotrophic status.
