The City of Mankato says storm drains play an integral role in the city’s stormwater drainage system. Heavy rains can cause debris, such as leaves and sticks, to clog a storm drain and prevent it from doing its job and cause flooding. If a clogged storm drain is seen, please help us help you by removing any debris, or complete a customer service request.
