ISU lakes classification study.
Basis for Assessment
Lake was assessed at PS for the 1992 report. Results from ISU monitoring in 1990 show total-P, NO3, and TSS in the highest 33 percent of the 96 lakes sampled. Levels of secchi depth were relatively low (0.3 m), while the average level of chl-a was also low, thus suggesting turbidity due to suspended sediment. Thus, data suggest a water quality problem due to agricultural runoff.
