Abstract :This paper deals with the limnological results in lake Hinuma of brackish in Ibaraki Prefecture which were got on October 26th, 1964 at the stat. Nos. 1 to 5 and on 27th at the stat. Nos. 6 to 9 (Fig. 1). Water temperatures at each station are distributed almost uniformly from surface to bottom without prominent stratification (Table 2). They tend to decrease progressively going towards the west area of the lake from the east area nearer to the sea (Table 2). This fact must be caused by the inflowing cool water from the Hinuma River at the west end of the lake. Chlorine ion concentrations are very low in this time as compared with those of the previous reports and indicate the vertically uniform distribution at each station (Table 3). These values also become lower going towards the west area from the east area of the lake. This fact must also come from the influence of the inflowing water of the Hi-numa River. Colors of water in Ule's scale are No. 14 or 15 at the all stations in the
