Chemical analyses were made of the surface waters of 61 Iowa lakes and reservoirs during the summer of 1964. With the exception of one bog lake, they all had typical hard waters of the bicarbonate type. Their average composition was similar to the 10-year average compositions of the Iowa and Cedar rivers. There was a tendency for the lakes lying within the Wisconsin glacial drift sheet to have higher values for all parameters measured, although the differences were not considered biologically significant.
