     There is more we can do to lower the levels of Chlorophyll-a and Total Phosphorus. Chlorophyll-a is a measure of the amount of algae growing in our lake, and too much Total Phosphorus damages our lake by feeding the growth of algae.
     What can you do to keep the trend going in a positive direction? There are a number of initiatives and best management practices that help us improve water quality:
  • shoreline buffer zones
  • rain gardens
  • zero phosphorus fertilizer as outline in Minnesota statutes
  • Reduction of curly-leaf pondweed, an invasive aquatic species that dies off in early July and dumps nutrients in our lake as it decays​
