Cache County, UT — Daily Water Intelligence Brief

April 24, 2026

Situation Summary

Cache County agricultural water users are entering the 2026 irrigation season facing a significantly below-normal water supply outlook. Snowpack across the Bear River Basin is largely depleted or well below median for late April, reflecting an extreme early-season melt that stripped most of the region's water reserves ahead of schedule. While a few higher-elevation stations retain meaningful snowpack, the overall picture points to constrained surface water availability through the summer months. Water managers and irrigators should be actively adjusting plans to account for reduced supply and elevated curtailment risk.

Snowpack Conditions

As of April 23, 2026, snowpack conditions across Bear River Basin SNOTEL stations range from essentially gone to moderately below normal at the highest elevations.

Lower and mid-elevation stations have little to no snow remaining:

Higher-elevation stations retain more snow but remain significantly below normal:

The upper-elevation stations provide some encouragement — USU Doc Daniel in particular is the strongest performer in the network — but the near-total absence of snowpack at lower and mid elevations means the melt-driven runoff window has already largely closed for much of the watershed. The remaining snowpack at upper elevations represents the primary remaining surface water contribution for the season.

Streamflow Conditions

As of April 24, 2026, streamflow conditions across monitored Bear River Basin gauges show a mixed picture, with some flows still active but trending downward at key points.

The falling trend on the Bear River near Corinne and the Little Bear River at Paradise warrants close attention. With snowpack largely depleted at lower elevations, flows dependent on continued melt contribution may decline more rapidly than in typical years. The rising signal at the Wyoming border station is notable but should be interpreted cautiously given broader snowpack deficits.

Key Reservoir Systems

The primary storage systems serving Cache County and the broader Bear River Basin include Hyrum Reservoir, Porcupine Reservoir, Bear Lake (a natural lake managed for storage), Cutler Reservoir, and Scofield Reservoir (broader system). For current storage data, users are directed to the U.S. Bureau of Reclamation (usbr.gov) and the Utah Division of Water Resources. Do not rely on prior-year storage figures for current planning decisions.

Water Rights Administration Outlook

Given the significantly below-normal snowpack and early depletion across most of the basin, there is a high likelihood that surface water rights — particularly junior priority rights — will face curtailment pressure during the summer months. The Bear River is an interstate compact river subject to compact administration among Utah, Idaho, and Wyoming, adding a layer of complexity to supply management.

Water right holders with junior priority dates should consult with the Utah Division of Water Rights and their local water conservancy district regarding current and anticipated administrative conditions. Do not assume that flows observed today will persist through peak irrigation demand in June and July. Early communication with your water supplier about expected delivery schedules is strongly advised.

Groundwater Considerations

Cache Valley sits atop the Cache Valley Groundwater Basin, which provides supplemental supply for many agricultural operations. In low surface water years, pressure on groundwater increases substantially. Users considering expanded groundwater pumping should verify that their water rights authorize the additional use and should contact the Utah Division of Water Rights before increasing withdrawals. Aquifer response to increased pumping may affect neighboring wells, and coordinated communication among users is encouraged.

Historical Context

The 2026 season shares characteristics with several notable low-snowpack years in the Mountain West. The 2021 drought year brought significant curtailments across Utah and Idaho, forcing agricultural adjustments and, in some areas, emergency groundwater measures. The 2015 season — one of the warmest and driest on record at that time — resulted in early snowmelt patterns similar to what the region is experiencing now, with widespread impacts on irrigated agriculture. The 1977 drought remains a benchmark low-water year, with outcomes that included severe curtailments and lasting changes to how some water management entities approach storage and demand planning. While each year is distinct, these analogs underscore that early-melting, low-snowpack seasons carry real and substantial risk for irrigated agriculture throughout the summer.
