Salt Lake County Water Intelligence Brief

July 13, 2026 | Free-Tier Edition

1. Situation Summary

Salt Lake County's three municipal suppliers — Salt Lake City Public Utilities, Jordan Valley Water Conservancy District, and Metropolitan Water District of Salt Lake & Sandy — are operating under a supply profile defined by an anomalously early 2026 snowmelt season, with all monitored SNOTEL stations having melted out 4–6 weeks ahead of the historical median meltout date. Imported Provo River Project supply via Provo Reservoir Canal (from Deer Creek and Jordanelle reservoirs in Wasatch County) remains a critical variable for south and west county service areas, while canyon watershed inflows to Mountain Dell and Little Dell reservoirs have transitioned to late-season baseflow conditions. Reservoir storage data and 7-day forecast details are available in the full brief.

2. Snowpack Conditions

All five SNOTEL stations monitoring Salt Lake County's Wasatch Front watersheds are reporting zero snow water equivalent (SWE) as of July 12, 2026 — a condition that is normal for this point in the calendar year, as median SWE values for mid-July are also 0.0" at these elevations. The significant signal for 2026 is not current SWE but meltout timing: snowpack across all stations melted out 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave across the Mountain West. This compressed the spring runoff pulse and reduced the duration of snowmelt recharge to canyon reservoirs and streamflows.

Station readings (July 12, 2026):

⚠ Station record note: Atwater (SNTL 1308, reporting since August 2022) has fewer than four years of record and should not be weighted equally for trend comparison. Brighton (reporting since 1986), Mill-D North (since 1988), and Snowbird (since 1989) are the primary stations for historical context.

3. Streamflow Conditions

Two active USGS gauges are currently transmitting data in Salt Lake County. Both are reporting falling flows consistent with the transition from snowmelt-driven runoff to summer baseflow conditions.

⚠ Gauge data gap: Big Cottonwood Creek (gauges 10168499 and 10169000), Mill Creek (10170000), and Parleys Creek (10171500) are discontinued gauges not currently transmitting data. These drainages feed directly into Salt Lake City Public Utilities' canyon watershed storage system. Municipal water managers and utility staff requiring current flow data for Big Cottonwood, Mill Creek, or Parleys Canyon should contact Salt Lake City Public Utilities directly for operational monitoring data beyond what USGS provides.

— Agricultural Users: Secondary Section —

*The following guidance is provided for agricultural users in south and west Salt Lake County (Bluffdale, Herriman, Riverton, Magna). Agricultural water use represents a small fraction of total county demand; municipal supply framing above is the primary context for this brief.*

Agricultural irrigators in Salt Lake County depend primarily on Jordan Valley Water Conservancy District deliveries and direct Jordan River diversions. With Little Cottonwood Creek measuring 4 cfs and falling, and the Jordan River at 120 cfs and falling, late-season surface supply is tightening. Contact JVWCD for current agricultural delivery scheduling.

Data Sources: SNOTEL data through July 12, 2026; USGS streamflow data through July 13, 2026
