An emergency location information service (E-LIS) for water-based network devices. The E-LIS includes a server application and server network devices that accepts emergency messages from water-based network devices. The water based network devices comprise one or more sensors or one or more actuators, a wireless connection interface including a wireless low power wide-area ultra-narrowband network interface and a wireless low earth orbit satellite network connection interface and is an automated network device capable of sensing is own environment and automatically sending out the one or more emergency messages or one or more emergency text messages without operator input to an E-LIS server network device when an emergency event occurs on a body of water. The E-LIS server network device provides a current physical geographic location for such water-based network devices and/or users of the water-based network devices in an emergency situation on the body of water such as a river, lake, sea, ocean, etc.
