(The following is an excerpt from draft Mississippi River-Winona TMDL - final version to be published later in the spring of 2015): Lake Winona’s eutrophication impairments were characterized by phosphorus and chlorophyll-a concentrations that exceed state water quality standards and Secchi transparency depths below the state water quality standards. Excessive nutrient loads, in particular total phosphorus, lead to an increase in algae blooms and reduced transparency – both of which may significantly impair or prohibit the use of lakes for aquatic recreation.
