During Floods—What You Should Do

If you live in an area that is prone to flooding, always stay tuned to your local news and weather channels for the latest information. During a flood, if the waterway in your area is expected to rise significantly, your local emergency management agency and local media will broadcast any notifications.

If you have and emergency, please call 911 or your local emergency management agency.

The U. S. Coast Guard is the governing authority to halt navigation along any waterway.
