Leaves left in the street reach our lakes, rivers, creeks and wetlands via the storm sewer system and release phosphorus as they decay. Even small amounts of phosphorous can cause increased algae blooms and excessive weed growth in lakes and ponds. Algae and weeds decrease water quality for plants, animals, and for people who use Lake Nokomis for recreation.

This is what algae looks like in our lake.

While improvements have been made to prevent storm water from directly flowing into Lake Nokomis on the West side of the lake, there are still a dozen or more points of entry into the lake directly from the storm water system on the Eastern shore, making the issue of proper lawn care and leaf pickup one that should not be taken lightly.

Protect our water bodies by not raking leaves into the street. Follow these water-friendly tips when cleaning up leaves around your home:

  • Compost leaves to provide rich organic matter for your lawn and garden.
  • Chop leaves with your mower; a fine layer of leaves provides nutrients for your lawn.
  • Use leaves as mulch for bushes and plants.
  • As a last resort, bag leaves for pickup.
