Opinion

EISMANN, Chief Justice.

This is an appeal by water users within an irrigation district from a judgment of the district court determining that water lost when the district uses a section of river to convey its water to downstream diversion points for distribution to water users in the district must be allocated pro rata among those water users. We affirm the judgment of the district court.

I. FACTS AND PROCEDURAL HISTORY

The Big Lost River Irrigation District was formed in 1920 to deliver irrigation water to its members who had decreed water rights. In 1936, it purchased the Mackay Dam and Reservom and storage water rights in the reservoir in order to supplement the decreed water rights owned by various water users in the District. The Mackay Reservoir is on the Big Lost River, and the District uses the river to convey the storage water from the reservoir to various diversion points, through which the storage water is diverted from the river for delivery to landowners within the District. Because of the gravel deposits and porous soils through which the river flows, a significant amount of the storage water is lost by seepage while it flows down the river from the reservoir to the diversion points. This loss of water is called “conveyance loss” or “shrink.” The lower reaches of the river experience significantly greater shrink than do the upper reaches.

Over the years, the Irrigation District has dealt in various ways with allocating the conveyance loss among its water users. Prior to 1994, the District used the “universal shrink” method under which the conveyance loss was allocated on a pro rata basis to all landowners in the District, regardless of the locations of their respective points of diversion from the river. Beginning in 1994, it generally used a formula that apportioned the conveyance loss to various sections or reaches of the river, resulting in a larger percentage of the loss being apportioned to its water users who were farther downstream. On May 5, 2005, the Directors voted to resume using the universal shrink method.

The Plaintiffs are sixty-four landowners who receive storage water that is diverted from the upper reaches of the river. On July 28, 2005, they filed this action against the Irrigation District and its Directors seeking to prevent implementation of the universal shrink method of allocating the conveyance losses. Plaintiffs alleged that the storage water they received from the river should be administered as if they were the appropriators of the natural flow from the river rather than landowners within an irrigation district. 1

On August 12, 2005, the Plaintiffs filed an amended complaint adding a claim for a declaratory judgment that IDAPA Rule 37.03.12.040.03.b (Rule 40.03.b) adopted by the Idaho Department of Water Resources required apportionment of the conveyance loss by reach. The Irrigation District re *159 sponded by filing a counterclaim also asking the court for a declaratory judgment regarding the meaning of the Rule. Because both the Plaintiffs and the District were seeking a declaratory judgment as to the meaning of the Rule, the district court required that the Plaintiffs join the Department as a defendant in this action. On June 19, 2006, the Plaintiffs filed a second amended complaint, adding the Department and its Director 2 as defendants.

A group of approximately 448 water users (Intervenors) were granted permission to intervene in this action as defendants. Approximately 188 of them are landowners in the Irrigation District whose lands are located downstream from the Plaintiffs’ properties and who are entitled to the use of the storage water. The others are landowners within or near the District who are not entitled to the use of the storage water but who contend they would be harmed if the District reverted back to apportioning losses by reach. The Intervenors filed a counterclaim and cross-claim in which they sought a declaratory judgment that the District was required to allocate the conveyance loss on a universal or proportionately equal basis.

The Plaintiffs and the Irrigation District filed cross motions for summary judgment seeking a ruling as to the interpretation of Rule 40.03.b. That Rule provides:

Conveyance losses in the natural channel shall be proportioned by the watermaster between natural flow and impounded water. The proportioning shall be done on a river reach basis. Impounded water flowing through a river reach that does not have a conveyance loss will not be assessed a loss for that reach. Impounded water flowing through any river reach that does have a conveyance loss will be assessed the proportionate share of the loss for each losing reach through which the impounded water flows. To avoid an iterative accounting procedure, impounded water conveyance loss from the previous day shall be assessed on the current day.

The Irrigation District is located in Water District 34. Because the Irrigation District uses the river to convey its storage water to its water users, it must permit the watermaster of the Water District to distribute the water from the river into the Irrigation District’s waterworks, and it must compensate the watermaster for those services. I.C. § 42-801. When the Irrigation District’s storage water is in the river, it may be comingled with natural flow water. When the storage water is reclaimed from the river, there must be due allowance made for conveyance loss in order not to diminish the amount of natural flow water to which downstream users may be entitled. I.C. § 42-105(1). Therefore, the Department adopted Rule 40.03.b to specify how the Department’s watermaster is to allocate such conveyance loss between natural flow and impounded water as it flows down the river.

The district court held that Rule 40.03.b did not apply to the Irrigation District’s allocation of conveyance loss among its water users. The Department’s director has “direction and control of the distribution of water from all natural water sources within a water district to the canals, ditches, pumps and other facilities diverting therefrom,” I.C. § 42-602, including “water ... turned into the channel of a natural waterway and mingled with its water, and then reclaimed,” I.C. § 42-105. In order to perform that function, the director must divide the state into water districts. I.C. § 42-604. The director is also authorized to adopt rules and regulations “for the distribution of water from the streams, lakes, ground water and other natural water sources as shall be necessary to carry out the laws in accordance with the priorities of the rights of the users thereof.” I.C. § 42-603. Water districts are created pursuant to Idaho Code § 42-604, while irrigation districts are created pursuant to Idaho Code § 43-101 et seq. The board of directors of an irrigation district is authorized “to establish equitable by-laws, rules and regulations for the distribution and use of water among the owners of such land [within the district], as may be necessary and just to *160 secure the just and proper distribution of the same.” I.C. § 43-304.
