Abstract: A water level measuring apparatus for a water storage container. The water level measuring apparatus includes a water pressure sensor disposed at a bottom of the water storage container to generate water pressure data and a controller for determining a water level in the water storage container based upon the water pressure data generated by the water pressure sensor. A water monitoring system including a water level measuring apparatus to determine pressure data associated with a water container. The water monitoring system also includes a water level control system that sends and receives information from the water level measuring apparatus. A method of monitoring water levels in water containers. Water pressure data is captured from the water containers. The pressure data is sent from the water level measuring apparatus of the water monitoring system to the water level control system of the water monitoring system. Water depth data is generated for the water containers from the pressure data.
