Cache County, UT — Agricultural Water Intelligence Brief

Bear River Basin | Issued: May 26, 2026

1. Situation Summary

Cache County agriculture faces a critically tight water supply situation as the 2026 irrigation season moves into its peak demand period. Snowpack across the Bear River Basin is essentially gone — well ahead of any normal seasonal timeline — and streamflows on local tributaries are falling or holding at modest levels. Dairy operations, the backbone of Cache County's agricultural economy, along with alfalfa producers, should be operating under the assumption that surface water availability will be constrained through the remainder of the season. Proactive planning, efficiency investments, and early communication with water managers are strongly advised.

2. Snowpack Conditions

Snowpack in the Bear River Basin is, for all practical purposes, depleted. Six of eight active SNOTEL stations are reporting zero snow water equivalent (SWE) and zero snow depth as of May 25: Bear River RS, Emigrant Summit, Garden City Summit, Giveout, Slug Creek Divide, and Tony Grove Lake — the last of which sits at 0% of its 15.1-inch median SWE.

Two stations retain marginal snowpack. Franklin Basin shows 0.4 inches SWE, representing just 8% of its 5.0-inch median. USU Doc Daniel carries the most remaining snowpack in the monitored network at 8.2 inches SWE (38% of the 21.3-inch median) with 19.0 inches of snow depth — a meaningful remnant, but still dramatically below what would be expected at this time of year. Neither of these remaining snowpack reserves is sufficient to meaningfully extend irrigation season runoff. The basin's seasonal snowmelt contribution to streamflow should be considered largely exhausted.

3. Streamflow Conditions

Local tributary flows reflect the depleted snowpack. The Logan River above State Dam, near Logan, is flowing at 292 cfs and holding stable — providing some near-term supply for Logan River water users, but without snowpack to sustain it, this level is not expected to hold through the summer. Blacksmith Fork above the Upper and Lower Canal Company's dam near Hyrum is at 67 cfs and stable. Little Bear River at Paradise is at 32 cfs and falling — a concerning trend for users on that system.

On the broader Bear River mainstem, flows are mixed. Bear River at Pescadero, ID is at 883 cfs and rising, while Bear River at the Wyoming border is at 194 cfs and falling. Bear River near Corinne, UT — reflecting conditions at the lower end of the system — is at 141 cfs and falling. The Malad River near Bear River City was last recorded at 6 cfs as of May 15; this gauge has not updated in approximately 11 days, and users dependent on Malad River system water should seek current readings directly from USGS or their water district.

Overall, the trend across local streams is stable-to-falling, consistent with the end of meaningful snowmelt contribution.

4. Key Reservoir Systems

Cache County water users are served by several reservoir systems within the Bear River Basin. Key storage facilities include:

Current storage conditions are not available in this data feed. Users should contact the U.S. Bureau of Reclamation, the Bear River Commission, or their local irrigation company for current storage figures. Given the extremely poor snowpack year, reservoir managers should be consulted early regarding anticipated carry-over storage and release schedules.

5. Water Rights Administration Outlook

Given the significantly below-normal snowpack, falling local streamflows, and the broader context of one of the worst snow years on record in the Mountain West, the risk of water rights curtailments in Cache County is elevated for the 2026 irrigation season. Utah Division of Water Rights administers priority-based water rights ("first in time, first in right"), and in low-water years, junior priority rights are most exposed to curtailment or reduced delivery.

Water users with junior water rights on the Logan River, Blacksmith Fork, Little Bear River, and tributary systems should engage proactively with their water commissioner and local canal companies. Those holding storage rights should clarify fill status promptly. The situation warrants close monitoring — formal curtailment actions become more likely as summer demand peaks and flows continue declining.

6. Groundwater Considerations

Cache County agricultural users draw from the Cache Valley Groundwater Basin, an alluvial aquifer system underlying Cache Valley. In low surface water years, pressure on this aquifer typically increases as irrigators shift toward supplemental groundwater pumping. Users considering increased pumping to compensate for reduced surface water deliveries should verify that their water rights authorize groundwater use at the intended volumes and timing. Sustained increased withdrawals across the valley could contribute to aquifer drawdown. Contact the Utah Division of Water Rights before making significant changes to groundwater pumping schedules or volumes.

8. Historical Context

The 2026 season shares characteristics with several historically difficult water years in the Mountain West. The 1977 drought remains a benchmark low-water year that resulted in widespread curtailments, emergency water-sharing measures, and significant agricultural adjustments across Utah and the broader region. 2015 brought another severe low-snowpack year with early melt timing similar to 2026, leading to significant curtailments and stressed forage production across Cache and Bear River Basin communities. 2021 produced critically low snowpack and reservoir storage across Utah, resulting in mandatory conservation measures and difficult priority administration decisions on multiple river systems.

In each of these analog years, agricultural users who planned early and secured supplemental forage or water supplies were better positioned than those who waited for official shortage declarations. The 2026 outlook warrants treating those historical episodes as a serious reference point.
