Minnehaha County Emergency Management announced on April 4 that it will begin testing outdoor warning sirens on the first Monday of each month at 7:00 PM, starting April 6. The new schedule applies to areas in Minnehaha County but does not include the City of Sioux Falls, where siren tests are conducted separately.
The regular testing is intended to ensure that emergency alert systems are functioning properly and can effectively warn residents in case of severe weather or other emergencies. Sioux Falls will continue its own siren tests on the first Friday of each month at 11:00 AM.
The Minnehaha County Sheriff’s Office functions as the primary law enforcement agency in Minnehaha County, focusing on public safety and community well-being through dedicated services. It provides essential operations such as jail management, fingerprinting, concealed carry permits and civil support, while partnering with local entities to foster a secure environment, according to the official website.
The Sheriff’s Office enhances community well-being by upholding professionalism, integrity and compassion in its duties. It utilizes the Law Enforcement Center for its operational facilities and extends protective services throughout Minnehaha County. The office also works with community and professional partners to promote safety across various jurisdictions according to information from the official website.
Residents are encouraged to be aware of these scheduled tests so they do not mistake them for actual emergencies. The ongoing collaboration between emergency management officials and law enforcement aims to maintain a high level of preparedness within the county.
