The Spring Lake Park Swim Facility has been closed. North Mankato City officials say the facility was closed as a precaution due to a possible COVID-19 exposure in one or more of its staff members. City Administrator John Harrenstein says the Spring Lake Park will remain closed as the city works with Public Health officials to determine who may have been exposed at what, if any risk, remains to pool guests and staff. Harrenstein adds the city does not believe there is concern about widespread exposure to pool guests and staff.
