Make a difference today: Take the Vow

Please consider adding your name to this list of homeowners who have agreed to stop their use of lawn fertilizer in the interest of preventing Harmful Algal Blooms (HABs).

You have the power to protect public health and the water quality of Owasco Lake directly.

Why is the vow 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 and cease the use of lawn fertilizer today.
