The City of Saint John says swimming at Lily Lake is shut down after Public Health found elevated bacteria levels during recent water testing.
The city said swimming is not permitted until further notice.
Warning signs are posted at the site, and lifeguards will remain on duty during regular operating hours to advise visitors and help ensure safety.
Health Canada distinguishes between primary‑contact activities, such as swimming and wading, and secondary‑contact activities, including canoeing, kayaking, boating and fishing.
According to Health Canada, some recreational waters may still be suitable for secondary‑contact activities even when they are not suitable for swimming.
The city said this weekend’s Dragons on the Lake Dragon Boat Festival will proceed as scheduled because dragon boating involves a lower level of water exposure.
Participants and spectators are being encouraged to limit unnecessary contact with the water, avoid swallowing it, and avoid exposure if they have open cuts or wounds.
The city said festival organizers have arranged on‑site washing facilities for participants.
No other Saint John beaches or swimming areas are affected by the closure.
The city said visitors can continue to enjoy Rockwood Park for walking, running, hiking, picnicking and other shoreline activities.
Testing at Lily Lake will continue, and the city said updates will be provided as Public Health determines when conditions are safe for swimming to resume.
