Shoreline Management | Erosion Prevention

When designing and installing lakeshore projects, Southview works with the DNR or watershed districts to be sure we follow their guidelines and restrictions. There are several factors to take into account. Here is a breakdown of a few goals to keep in mind when working with shorelines.

Preventing Erosion

The main cause of erosion is wave action from wind or boats. What makes erosion worse?

• Removal of native plants along the lakeshore.
• Common recreational activities too close to the shore.
• Removal of ice ridges.

Solutions:

• Install a buffer zone of native grasses between the lakeshore and your mowed lawn.
• Install a biolog, stabilizing roots of vegetation as it grows so that it can effectively take root and prevent future erosion.
• If vegetation is not an option, install rock or boulders as a buffer.

Preserving Water Quality and Health

Issue: Installing sod/lawn right up to the shore of the lake can cause several problems:

• Erosion.
• Fertilizer runoff into lake, causing algae blooms.
• Algae bloom kills fish by blocking their oxygen.
• Pet waste, pesticides, herbicides and other debris to runoff into the lake.
• Humans and animals should not be using contaminated water.

Solution:

Create a “buffer zone” of native plants, trees and flowers. This strip keeps human activity out of the shore-impact zone, creating a natural, beautiful, clean shoreline.

Create Habitats for Native Plants and Animals

Issues:

• Animal/plant habitat loss
• Fertilizers and pesticides running into the water
• Removing down natural grasses and trees to install sod
• Purposely killing the “weeds” in the water

Solution:

Replace traditional mowed lawns near the shore with native grasses, shrubs, flowers and trees.This requires little maintenance and plants love their native habitat. Native grasses and flowers will attract butterflies, hummingbirds, songbirds, and other important pollinators to the lakeshore.
