Lake Assessment Program 1992 - Roberds Lake

Roberds Lake was sampled during the summer of 1992 as part of the Minnesota Pollution Control Agency's (MPCA) Lake Assessment Program. Data collected during the study showed that in terms of total phosphorus, chlorophyll and Secchi disk transparency, the water quality of Roberds Lake is poorer than similar lakes in the North Central Hardwood Forest ecoregion of Minnesota. The mean summer concentrations of total phosphorus and chlorophyll were 150 and 64 ug/l, respectively, and the mean Secchi disk transparency was 3.6 feet. Based on these water water quality values Roberds Lake would be considered eutrophic to hypereutrophic.
