Protecting North Lake Together

As a group of like-minded neighbors committed to preserving and improving the health of North Lake, it is imperative that we all practice lake friendly living. The below guide outlines best practices for protecting the quality of North Lake. 


We hope all will recognize and follow the guidelines below with emphasis on prudent and proactive Septic Tank maintenance. 


Please visit the Septic Tank section of this site for recommendations for proper upkeep that, if followed, will have a profound and positive impact the Lake. 

Minimize & Address Runoff

Runoff picks up pollutants and carries them to the Lake. Minimize the hard surfaces that create runoff.                                            

Eliminate Pollutants

Eliminate pollutants at their source.

Avoid using fertilizer, household toxins, and other chemicals. Prevent soil erosion and failing septic systems.

Capture and Infiltrate

Capture and infiltrate any pollutant-carrying runoff that you didn’t eliminate before it reaches the Lake with shoreline buffers, rain barrels, and rain garden


Best Practices

Reduce Impermeable Surfaces 

Limit Lawn Size & Practice Smart Lawn Care

Use Phosphorus-Free Fertilizer 

Conserve & Use Water Wisely

Minimize Erosion 

Maintain Your Septic  System Properly

Don’t Flush Your Drugs 

Reduce Household Hazardous Wastes 

Install a Vegetative Buffer

Plant a Rain Garde

Install a rain barrel to collect runoff from your roof and use to water

Maintain Your Vehicles - Eliminate or reduce oil run off from boats & wave runners

What Can We Do To Make A Difference

Lake Friendly Lawn Care

Fertilizers, leaves, grass clippings, animal waste, and eroded soil are all sources of phosphorus. When they are swept or washed into the street or nearest storm drain, they end up in a nearby stream or the lake. Follow these tips for smart lawn care with water quality in mind. 

  • Apply fertilizer at the recommended rate. Fall is the best time. Don’t fertilize before a storm. Never apply to frozen ground. Or better yet, skip the fertilizer all together!
  • Yard waste can contribute significant amounts of phosphorus to water ways. Keep soil, leaves, and lawn clippings out of the street, ditches, storm drains, and streams by bagging, composting, or leaving leaves right on the lawn as a natural fertilizer. 
  • Mow higher! Keep grass length to roughly 3 inches. It is healthier for your lawn and means you can mow less often! 
  • Pick up pet waste. Pet waste can contain harmful bacteria as well as phosphorus. Flush it in the toilet or place it in the garbage.

When it comes to fertilizing, ZERO is more!

 It is best not to use fertilizer at all. However, there is a safer means to fertilize your lawn. When shopping for fertilizer, look for phosphorus-free fertilizer. Phosphorus free fertilizer can be identified by examining three numbers on fertilizer bags that show the N-P-K nutrient analysis. The middle number is the phosphate (phosphorus) content. A “zero” in the middle means it is phosphorus-free 

Phosphorus is not our Friend

Phosphorus can have a devastating impact on the water quality of our lake. Therefore, we need to be ever mindful of protecting the lake of it and keeping phosphorous levels as low as possible.


What is Phosphorus?  Phosphorus is a natural element and an essential nutrient for plant growth but is found only in small amounts in lakes and streams. Even small increases in phosphorus can lead to negative results such as stimulating algae growth and the unwanted green blooms as well as creating excessive plant growth in the lake. More phosphorus also leads to less fish as dying and decaying algae robs the water of dissolved oxygen fish require to thrive.
