Cunard Pond Beach in Spryfield has closed again to swimming.

It comes mere hours after reopening after a blue-green algae toxin testing, that indicated toxin levels were within Health Canada limits.

HRM now says there is another possible blue-green algae mat.

Water users are encouraged to take the following precautions:

• Do not touch or consume blue-green algae mat material.
• Avoid water contact. If contact occurs, towel off vigorously and wash with tap water as soon as possible.
• Do not swim or wade (or allow your pets to swim or wade) in any areas where blue-green algae is visible or in areas that have been closed to swimming due to possible blue-green algae.
• Keep pets on-leash and do not allow them to consume blue-green algae material.
• Avoid consuming water from this lake.
• Avoid consuming fish that has come from this lake.
