Notes:
Abstract Natural and artificial lakes in the most recently glaciated portions of Iowa have significantly greater total ion concentrations than those in other areas of the state. A similar distribution was found for total nitrogen concentrations. Lake origin seems of greater importance than location in determining trophic state. As a group, the artificial lakes have lower concentrations of total phosphorus, total chlorophyll, and greater Secchi disk transparency than do the natural lakes. This seems related to differences in the dynamics of the phosphorus cycles in these lake types.
