(1) The governing board of the district may by order declare that a water shortage exists within all or part of the district when insufficient ground or surface water is available to meet the needs of the users or when conditions are such as to require temporary reduction in total use within the area to protect water resources from serious harm.
(2) The governing board may impose such restrictions on one or more users of the water resource as may be necessary to protect the water resources of the area from serious harm.
(3) When a water shortage is declared, the governing board shall cause notice thereof to be published in a prominent place within a newspaper of general circulation throughout the area. Publication of such notice shall serve as notice to all users in the area of the condition of water shortage.
(4) If an emergency condition exists due to a water shortage within any area of the district and the executive director of the district, with the concurrence of the governing board, finds that the exercise of powers under this section is not sufficient to protect the public health, safety, or welfare, the health of animals, fish, or aquatic life, a public water supply, or recreational, commercial, industrial, agricultural, or other reasonable uses, the executive director may, pursuant to the provisions of chapter 120, issue emergency orders reciting the existence of such an emergency and requiring that such action, including, but not limited to, apportioning, rotating, limiting, or prohibiting the use of the water resources of the district, be taken as the executive director, with the concurrence of the governing board, deems necessary to meet the emergency.
