MASON CITY — Classes at Mason City High School, John Adams Middle School and the Alternative School were dismissed early today due to a water main break.

The break happened on the south side of the high school near the roundabout, causing standing water on the sidewalk and driveway on the southeast side of the school.

The schools dismissed at about 10:00 AM. City crews were scheduled to attempt to repair the break this afternoon. 

Visit the district’s website and social media for further information throughout the day as the District is also experiencing a PowerSchool issue and not able to send out notifications to families at this time.
