Nova Scotia lake deemed safe for swimming after blue-green algae prompts closure

WOLFVILLE, N.S. - A beach at a provincial park in Nova Scotia has reopened after a two-week closure because of blue-green algae.

The Health Department says inspections of the lake at Lumsden Provincial Park near Wolfville indicate the water is now safe for swimming.

The department says toxins from blue-green algae can cause stomach aches, diarrhea, vomiting and nausea if ingested.

It can also cause skin and eye irritation.

The algae is naturally occurring.
