Proposed Legislation First Step in Settling Reservoir Release Debate

In an often-arid, agricultural community, nothing is more precious than water, particularly in drought years. However, flood years present their own set of challenges as well. When it comes to water allocation, it’s not just how much water that matters, but also when that water is received. Timing is as important as quantity when it comes to water delivery, especially when taking into account the impact snow pack and snow melt has on water supply.

For irrigators in Idaho’s Treasure Valley, this issue has long been a topic of discussion and debate. Water is accumulated and stored in three major reservoirs (Arrowrock, Anderson, and Lucky Peak) and is released throughout irrigation season to water users through a series of canals. Water is diverted to users at various points on the canals, at which time it begins to count toward a user’s annual allotment of water. This is typically not an issue during years of normal water accumulation and distribution. However, when above-average quantities of water accrue in the reservoirs, water must be released earlier in the spring to prevent overflow and flooding.

Early “flood water” releases are the root of the current conflict concerning regulation of water storage in Idaho. Water rights holders are allowed only a certain amount of water under the conditions of their permits and/or certificates. When water is released out of storage earlier in the year, Idaho Water Resources Department advises that the meter starts running regardless of whether or not the water right holder is ready to turn the water into its irrigation facilities. For senior users (holders of rights with earlier priority dates), this means seniors risk running out of water later in the season. Typically, if a senior is not receiving their allowed quantity of water as flows decrease in the hotter months, the senior is able to make a water call on junior priority water right holders. However, if, due to the early release of water, the senior has technically received the storage release of their senior priority water, the senior could be left high and dry.

This issue has been litigated in the Idaho courts as a contested case since 2013, with argument before the Idaho Supreme Court scheduled to occur on June 20, 2018. However, on June 6, 2018, a joint legislative committee met and unanimously called for Governor Butch Otter to hold a special session to pass legislation that would add a new Section 42-115 to the Idaho Code. Section 42-115 would ensure that future water storage projects do not interfere with existing reservoirs. While this proposed legislation will not fully resolve the ongoing issues, nor constitute a settlement between the parties, it may be a positive first step toward resolution.
