Welcome back to our 2024 blog series on lake conservation. Quick recap:

• Conservation starts with community involvement in maintaining ecological balance and ensuring the sustainability of lake ecosystems. We must all work together to protect our waterways.
• Nonpoint source pollution (NSP) comes from runoff bringing contaminants into our lakes, accelerating eutrophication and harming aquatic life. Our second post provided practical tips for reducing NSP.

After streams and creeks that flow into our lakes, the shoreline is the next line of defense. The Lilly Center recommends using natural glacial stone over concrete for seawalls. In the water next to the seawall, consider cultivating a riparian buffer. Riparian buffers, the vegetated areas along the edges of lakes and streams, are crucial for protecting water quality and wildlife habitats. These buffers help to:

• Reduce Erosion: The roots of plants in riparian buffers stabilize the soil, preventing erosion and sedimentation in the water.
• Filter Pollution: Vegetation acts as a natural filter, trapping pollutants from runoff before they reach the water.
• Provide Habitat: These areas offer essential habitats for various species, enhancing the overall biodiversity of the lake ecosystem. Brush reefs and gravel beds provide shelter and breeding.

Keep these tips in mind as you repair or build a new seawall, after pulling the appropriate DNR permit. Next up in the series? Clean marina and boat tips.
