When the owner of a reservoir desires to use the bed of a stream or other watercourse for the purpose of carrying water from the reservoir to the consumer, he shall in writing notify the water superintendent of the district in which the water is to be used, giving the date when it is desired to discharge water from the reservoir, its volume, and the names of all persons and ditches entitled to its use. The superintendent shall supervise the opening of the reservoir gates and close or adjust the head gates of all ditches from the watercourse not entitled to the use of the stored water so that persons having the right will receive the water to which they are entitled.
