Cache County Water Intelligence Brief

June 29, 2026 | Bear River Basin

Situation Summary

Snowpack across the Bear River Basin monitoring network has fully melted out, with stations having melted out 4–6 weeks ahead of the historical median meltout date following an anomalous March heat wave. Streamflows across Cache County tributaries reflect this early-season transition, with most gauges running at stable late-season levels typical of July conditions. Reservoir storage data and 7-day forecast details are available in the full brief.

Snowpack Conditions

All eight SNOTEL stations in the Bear River Basin monitoring network serving Cache County show snowpack at or effectively at zero as of June 28, 2026. This reflects normal end-of-season conditions for this calendar date — the meaningful signal is not today's reading but rather that meltout occurred 4–6 weeks earlier than the historical median meltout date.

  • Bear River RS: SWE 0.0", depth 0.0"
  • Emigrant Summit: SWE 0.1", depth 0.0"
  • Franklin Basin: SWE 0.6", depth 1.0" — the only station with any meaningful remaining snowpack
  • Garden City Summit: SWE 0.0", depth 0.0"
  • Giveout: SWE 0.3", depth 0.0"
  • Slug Creek Divide: SWE 0.0", depth 0.0"
  • Tony Grove Lake: SWE 0.0", depth N/A
  • USU Doc Daniel: SWE 0.0", depth 3.0" — depth reading with no SWE suggests ice or compacted remnant, not active snowpack contributing to runoff

    • Franklin Basin is the only station registering SWE above trace levels. Any remaining snowpack contribution to streamflow from these stations is minimal and effectively exhausted for the season.

    Streamflow Conditions

    Streamflows across the Bear River Basin present a mixed picture as of June 29, 2026, with Cache County tributaries running at stable late-season levels while the Bear River mainstem shows more active conditions.

  • Bear River at Border, WY: 138 cfs (stable) — upper basin inflow reflecting post-peak conditions
  • Bear River at Pescadero, ID: 1,520 cfs (stable) — substantial mid-basin flow, likely reflecting reservoir operations upstream
  • Bear River near Corinne, UT: 492 cfs (rising) — the rising trend on the lower Bear River mainstem is notable and may reflect operational releases or tributary contributions; warrants monitoring
  • Blacksmith Fork above Upper and Lower Canal Co.'s Dam near Hyrum, UT: 59 cfs (stable) — a locally important tributary for Cache County agricultural users; stable flow at this level is manageable for current-season operations
  • Little Bear River at Paradise, UT: 21 cfs (stable) — lower flows consistent with late-season conditions on this smaller tributary
  • Logan River above State Dam, near Logan, UT: 153 cfs (stable) — the Logan River remains the highest-volume Cache County tributary gauge; stable flow at 153 cfs provides continued supply to Logan River system users
  • Malad River near Bear River City, UT: 6 cfs — note that this reading is dated May 15; current conditions at this gauge are unknown and users dependent on the Malad River corridor should seek updated readings

    • The Malad River data gap is a meaningful limitation. Users with interests in the lower Malad corridor should contact the Utah Division of Water Resources or the USGS Utah Water Science Center for current conditions.

    Seasonal Guidance

  • Contact the Utah Division of Water Rights (waterrights.utah.gov) to verify your water right priority status and confirm current administrative conditions on Cache County water sources.
  • Reach out to your local canal company or irrigation district — including Logan River Water Users, Blacksmith Fork Irrigation, and Little Bear River system operators — to confirm current delivery schedules and any operational changes for the remainder of the season.
  • Check with the Utah Division of Water Resources (water.utah.gov) for current storage status at Hyrum Reservoir, Porcupine Reservoir, Newton Reservoir, and Cutler Reservoir, which are the primary storage facilities serving Cache County agricultural users.
  • Contact the NRCS Utah State Office or Cache County Conservation District for updated seasonal water supply outlooks and any available late-season irrigation efficiency resources.

    • Subscribe for the full brief including reservoir storage, weather forecasts, depletion analysis, and detailed operational recommendations.
