“Hidarimichi-numa” is an irrigation pond in Sakegawamura, Yamagata Prefecture. The present studies have been carried out chiefly from the hydrochemical point of view. Especially, the seasonal change of the quality of water is discussed in this paper. The results are summarized as follows :<BR>(1) The morphometrical data of this lake are given in the following table, <BR>surface area : 4, 350m2<BR>length of shore line : 352m<BR>maximum depth : 4.41m<BR>mean depth : 1.82m<BR>volume : 7, 940m3<BR>(2) The chemical analyses reveal that the main dissolved substance of the lake water is sodium chloride which is mainly transported by the monsoon. The concentration of dissolved ions is in the order : Cl->SO2-4>HCO-3 for anion and Na+>Ca2+>Mg2+>K+ for cation.<BR>(3) In summer, the development of thermal stratification is observed.<BR>(4) Judging from the photosynthetic productivity and the results of chemical analyses, this lake is deduced to be a mesotrophic lake.
