% of Vermont’s rivers and lakes (excluding Lake Champlain) that meet State water quality standards for swimming
Story Behind the Curve
This data is compiled and analyzed every two-years/bi-annually; annual fluctuations are expected due to updated assessment data reflecting the current conditions on our waters. There are over 55,000 acres of lakes in the state of Vermont; of these acres 85% support swimming/recreational uses (75% consistently, and 10% where they are occasionally limited due to conditions that make swimming less desirable at times). The remaining 15% are consistently limited due to aquatic invasive species, and/or cyanobacteria (blue-green algae) blooms. The 1% increase in support swimming/recreational use from last reporting period was due largely to progress with Ticklenaked pond and progress within some water bodies in managing aquatic invasive species.
