Weekly Status
Activity level will be updated regularly, and weekly when there is a change in status.
Status Update: July 3, 2008

Alert Level Descriptions
Below is a map of Lake Champlain which displays areas where blooms are present during the season. The color-coded map illustrates the following alert levels:
- Generally safe (white) - no toxic blue-green algae blooms were present along these shoreline areas when we sampled. These areas should be safe for recreational uses.
- Low alert (light green) - these shoreline areas have blue-green algae that produce toxins, but toxin concentrations are currently below levels of concern. These areas are open for recreation, but caution is advised in any areas where dense accumulations or scums are apparent.
- High alert (dark green) - these shorelines have blue-green algae in dense scums, at least in some areas, and toxin concentrations are above levels of concern. The water is not safe for recreational use in areas that contain scums. Please see Department of Health information about beach closings and hazardous areas.
