Fall is a beautiful time around the lake, with colorful leaves drifting down and covering the shores. While it’s natural for some leaves to fall into the water, it’s important not to add to that by raking or blowing them directly into the lake. Please also use care when clearing leaves into the street, since storm drains can carry them right back into the lake.
When too many leaves end up in the lake, they release nutrients that feed algae and aquatic weeds. This can trigger harmful algae blooms and encourage weed growth near your property. As algae and weeds die off, bacteria break them down and use up oxygen in the water, leaving less for fish and other aquatic life.
Better options for managing leaves:
Each of the four towns surrounding Lake Hopatcong prohibits disposing of leaves in the lake. To make fall cleanup easier, we’ve included links to ordinances and disposal guidelines for each municipality below.
Please share this information with neighbors and lawn maintenance services who may be unaware of the detrimental effects of depositing leaves into the lake. By working together, we can protect Lake Hopatcong’s water quality and beauty for generations to come.
Please refer to your town's website for full details on vegetative disposal or pickup.
