Lake Assessment Program - Lewis Lake, Kanabec County

Document
Description
Lewis Lake is a moderate sized lake (258 acres) located in Kanabec County. Land use in the watershed is characterized by cultivated (3 3 percent) and forested (29 percent) uses. This land use composition is typical for lakes in this region of the state - the North Central Hardwood Forests ecoregion (Figure 1 ). Lewis Lake was sampled during the swnmer of 1997 by Minnesota Pollution Control Agency (MPCA) staff and citizens from the Lewis Lake Association (Association). Water quality data collected during the study reveal a swnmer mean phosphorus concentration of 23 ?g/L, mean chlorophyll-a of 8 ?g/L and Secchi transparency of 7.8 feet. The phosphorus, chlorophyll-a and Secchi values are well within the range of values exhibited by reference lakes in this ecoregion. Total phosphorus, chlorophyll-a and Secchi transparency help to characterize the trophic status of a lake. For Lewis Lake, these measures indicate mesotrophic conditions.
