Make a difference today:

Take this pledge to refrain from using fertilizer on your lawn. This will help minimize the excess nutrients entering our waterways. Nutrients are a leading driver of Harmful Algal Blooms (HABs).

Thank you for your time and support!

Lawn Fertilizer (NYS Nutrient Runoff Law)

Why is the pledge so important?

  • Harmful Algal Blooms (HABs) are produced when cyanobacteria, photosynthetic organisms that live in freshwater, grow out of control due to an excess of nutrients entering the lake.

  • HABs produce toxic compounds that have harmful effects on the public and wildlife such as gastrointestinal illness and liver damage, both of which can be debilitating or fatal. 

  • HABs can be reduced by limiting the amount of nitrates and phosphates entering the Owasco Lake watershed. When homeowners apply fertilizer, they are not only feeding their grass, but the algae and invasive weeds too. Every homeowner's lawn fertilizer within the Owasco Lake Watershed drains to the lake through runoff after rain events.​ 

Consider becoming a part of the solution today and commit to refraining from the use of widespread lawn fertilizers and chemicals.
