Help sought to protect Oswegatchie River from invasive water chestnut

water chestnutSt. Lawrence County– Volunteers are needed to assist a removal effort of water chestnut on the Oswegatchie River near the dam, in the Village of Heuvelton.

The removal effort is scheduled for Saturday, June 25th, 2022. Food will be provided by the Village of Heuvelton Fire Department to those who assist the effort. This is a great opportunity for community members to spend some time on the water, and help protect the Oswegatchie River.

Water chestnut is an invasive aquatic species that have environmental and economic impacts.  Water chestnuts grow thick dense floating mats that shade out native aquatic vegetation, impede outdoor recreation, and reduce shoreline property values; the hard, pointy seeds of water chestnuts can puncture vehicle tires or injure feet if stepped on. If not managed, the infestation of water chestnuts on the Oswegatchie River can grow and easily spread to connecting waterbodies, like Black Lake.
