High bacteria levels have brought swimming to a halt at a popular lake in Saint John, New Brunswick, according to a report by Melanie Price published on July 8, 2026. A sign warns that no swimming is allowed, as elevated bacterial counts pose health risks to swimmers.
Details of the Swimming Ban
The ban was implemented after routine water quality tests revealed bacteria levels exceeding safe thresholds. The affected lake is a common recreational spot for residents and tourists. Local authorities have posted warning signs and are advising the public to avoid contact with the water until further notice.
“The safety of swimmers is our top priority,” said a city official. “We are monitoring the situation closely and will lift the ban once bacteria levels return to normal.”
Health Risks and Precautions
High bacteria levels can cause skin infections, gastrointestinal illnesses, and other health problems. Officials urge people to heed the warnings and refrain from swimming or engaging in water activities. The source of the contamination is under investigation, with possible causes including stormwater runoff, sewage overflows, or wildlife activity.
Impact on Community
The swimming ban has disrupted summer plans for many families and visitors. Local businesses that rely on lake tourism may see reduced foot traffic. City officials are working to resolve the issue quickly and have increased testing frequency to track bacteria levels.
