Abstract
The present paper deals with the limnology of the Gosikinuma Lake-Group of Volcano Bandai. Many lakes fill small basins on the surface of mud flows that poured out of Volcano Bandai at the time of its famous explo-sion in 1888. Twelve of these lakes were surveyed in the middle of Aug. 1935. Their areas ranged from 2, 000 to 100, 000 sqm, and their depths from 2.7 to 13 meters.
They had singular stratifications of water temperature, pH, and dissolved oxygen, because their waters were partly supplied by the warm and acidic-underground water from the explosion crater. The limnology of them are seen from the following table.
