Box Elder County, UT — Agricultural Water Supply

May 15, 2026

1. Situation Summary

Box Elder County agriculture faces a critically stressed water supply entering the peak irrigation season. With snowpack across the Bear River Basin largely exhausted and the 2026 season already recorded as one of the worst snow years on record in the Mountain West, available supply is significantly below what most operations require. An extreme March heat wave accelerated snowmelt well ahead of schedule, eliminating the seasonal snowpack buffer that typically sustains summer irrigation flows. Farmers growing row crops in the Tremonton area, alfalfa producers, and orchardists on the Wasatch Front should treat current conditions as a high-risk supply environment and begin active conservation and contingency planning now.

2. Snowpack Conditions

The Bear River Basin snowpack is effectively gone for the season at nearly all monitored elevations. As of May 14, 2026, six of eight SNOTEL stations in the basin report zero snow water equivalent (SWE) and zero snow depth:

Two higher-elevation stations retain minimal residual snowpack:

The sole meaningful outlier is USU Doc Daniel at 13.1" SWE (49% of its 26.6" median) with 31.0" snow depth. While this station reflects a more substantial remaining snowpack, it is an exception within an otherwise depleted basin and does not materially offset the basin-wide deficit. No meaningful additional snowmelt contribution should be expected from the lower and mid-elevation stations. The seasonal snowpack recharge window has effectively closed.

3. Streamflow Conditions

Current streamflow in the Bear River system is mixed across monitoring points, though falling or stable trends at most stations suggest the spring runoff pulse is diminishing. As of May 15, 2026:

The Bear River near Corinne at 284 cfs falling is the key indicator for Box Elder County agricultural diversions. The falling trend at this station and at Pescadero suggests that peak seasonal flows have passed or are passing. The Malad River near Bear River City at 6 cfs represents very limited supplemental contribution. Water users dependent on direct Bear River diversions should not anticipate improving supply conditions as the season advances.

4. Key Reservoir Systems

Box Elder County agricultural water supply relies primarily on regional storage and direct river diversions rather than dedicated local reservoir infrastructure. Key systems to monitor include:

Most Box Elder County agricultural water is delivered through direct Bear River canal diversions, primarily via the Bear River Canal Company and associated canal companies. Contact your canal company directly for current diversion status and delivery schedules. For reservoir storage data, contact PacifiCorp and the Bear River Commission.

5. Water Rights Administration Outlook

Given the severely depleted snowpack and falling streamflow trends, the probability of water rights curtailments affecting junior priority holders in the Bear River Basin is elevated for the 2026 season. Box Elder County users holding junior water rights — particularly those with priority dates later in the 20th century — should anticipate a high likelihood of reduced or interrupted deliveries as the irrigation season progresses into summer months.

Utah administers water rights under the prior appropriation doctrine. In low-water years, the State Engineer's office may issue curtailment orders protecting senior priority calls. Users are strongly advised to:

This assessment is advisory only. Formal curtailment determinations rest with the Utah Division of Water Rights and relevant water commissioners.

6. Groundwater Considerations

Box Elder County agricultural users in the lower Bear River valley overlie the Bear River Valley alluvial aquifer, which provides supplemental irrigation and livestock water supply for some operations. In years of surface water shortage, demand on this aquifer typically increases, which can affect water table levels and well yields over the course of a season.

Users considering increased groundwater pumping as a drought response should:

Groundwater is not a guaranteed buffer in severe shortage years and should be managed conservatively.

7. Management Recommendations

Immediate Actions (Next 2–4 Weeks)

Planning Actions (Season-Long)

Efficiency Actions (Ongoing)

8. Historical Context

The 2026 season shares characteristics with several historically challenging low-snowpack years in the Bear River Basin and broader Mountain West. The years 1977, 2015, and 2021 serve as meaningful analogs:

In all three analog years, users who planned early, established direct communication with water administrators, and implemented conservation measures were better positioned to manage through the season than those who relied on historical norms. The 2026 season warrants similar proactive engagement.
