✦ Synopsis

The seasonal variation in the vertical density profile of Lake Asejire waters was investigated from February I974 to February I976.

The range of density was of the magnitude of 2.o rag/cc, at the temperatures of Lake Asejire (21 o C_32o C). Water densities were generally lower in the dry season when aquatic temperatures were high and generally higher in the rainy season when aquatic temperatures were low.

During the dry season, the pycnocline was observed at 3 m -7 m in I974 and 6 m-9 m in I975. During periods of density stratification, the water body was clearly layered.

Seasonal longitudinal differences in water density were such that during the floods of I975 the inflow station waters had a higher density than the dam-site waters which however had a concomitantly higher conductivity. This suggests the insignificance of conductivity in water density changes in a lake with rather low conductivity values.
