An electronic device with a water level monitoring system monitors a buoy to determine if a water level is acceptable. The device separates level markers of the containment facility and the buoy floating therein. The device traces a trace of the movement of the buoy and compares the trace and security lines to determine if the water level is acceptable or not. If the water level is unacceptable, the device sends an alarm to an alarm mainframe to display a warning on a monitor array.
