Status of Blue-green Algae on Lake Champlain

Lake Status

October 1, 2012

This is the final Blue-green algae monitoring report for 2012.

Reports received last week indicated that blue-green algae populations are continuing to drop around the lake and no blooms were reported. The lake is considered safe for recreation but unreported localized blooms may occur. While fall blooms are not common, they do occur. Anyone active on or near the lake should continue to watch for and avoid blue-green algae blooms.

We thank all the volunteers who provided visual and sampling information for us this summer, as well as Angela Shambaugh at ANR, and the many others for their vigilence and hard work to keep Vermonters informed. A special note of appreciation to Dr. Mary Watzin and Susan Fuller, both of the Rubenstein School at the University of Vermont. Your unique and essential contributions to the state's monitoring efforts will be greatly missed!

Lake Status Map

The interactive Lake Champlain status map brings together in one place environmental and public health surveillance data about Blue-green Algae. The status of Blue-green Algae shown on the map reflects conditions and data as of the date of report. Observations and samples are collected once each week. Please note that current conditions may have changed. If you see Blue-green Algae, don't go in the water.

The map is a data collaboration project of the Departments of Health and Environmental Conservation.
