Intensive limnoecological surveys were conducted in 26 sand dune lakes including one spring pool from 2005 to 2007 in Niigata. There were two groups of sand dune lakes, Niigata sand dune lakes and Katamachi sand dune lakes. Lakes were characterized in the view of high and fluctuated water temperature, high pH values and comparatively low electric conductivity, whereas spring water had low water temperature, pH and dissolved oxygen concentration with small fluctuations. A water bloom by phytoplankton was observed in some lakes in Katamachi sand dune lakes. Origin and age of lakes were also discussed based on the formation age of sand dunes revealed by archaeological relics
