Lake Assessment Program - Wabana Lake, Itasca County

Wabana Lake was sampled during the summer of 1991 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 Wabana Lake is comparable to or higher than similar lakes in the ecoregion. Mean summer concentrations of total phosphorus and chlorophyll were 10.2 and 3.4329 ugn respectively and mean Secchi disk transparency was 4.9 meters (16.2 feet). Based on these water quality values Wabana Lake would be considered oligotrophic to mesotrophic.
