Salt Lake County Water Intelligence Brief

August 3, 2026 | Free-Tier Edition

Situation Summary

Salt Lake County enters peak summer demand under a post-melt seasonal profile: all monitored SNOTEL stations completed snowmelt well ahead of schedule, and streamflow indicators reflect late-season base conditions across the Jordan River basin. Municipal supply coordination among Salt Lake City Public Utilities, Jordan Valley Water Conservancy District, and the Metropolitan Water District of Salt Lake & Sandy remains the central operational priority for the county's 1.1 million residents. Reservoir storage data, conservation tier trigger analysis, and 7-day forecast details are available in the full brief.

Snowpack Conditions

All five SNOTEL stations monitoring Salt Lake County's canyon watersheds report zero snow water equivalent (SWE) and zero or trace snow depth as of August 2, 2026 — a condition consistent with normal late-summer baseline at these elevations for this date.

| Station | SWE | Depth |

|---|---|---|

| Atwater | 0.0" | 1.0" |

| Brighton | 0.0" | 0.0" |

| Dry Fork | 0.0" | 0.0" |

| Mill-D North | 0.0" | 0.0" |

| Snowbird | 0.0" | 0.0" |

Seasonal framing: The operationally significant signal for 2026 is not today's SWE reading — it is meltout timing. Across monitored stations, snowpack melted out approximately 4–6 weeks ahead of the historical median meltout date, driven by an anomalous March heat wave. This early meltout compressed the spring runoff pulse and reduced the total recharge window for canyon reservoirs and basin-fill aquifers alike.

Station record note: Atwater (UT:1308:SNTL) has been reporting since August 2022 — less than four years of record. Municipal water managers and policy stakeholders should weight Brighton (reporting since 1986), Mill-D North (since 1988), and Snowbird (since 1989) as the primary long-term trend indicators when conducting historical comparisons. Atwater data is useful for real-time monitoring but should not anchor multi-year analysis.

Streamflow Conditions

Two active USGS gauges provide current in-county streamflow data. Managers should note that gauges on Big Cottonwood Creek (10168499, 10169000), Mill Creek (10170000), and Parleys Creek (10171500) are discontinued and not transmitting current data. Contact Salt Lake City Public Utilities directly for canyon-specific flow data beyond Little Cottonwood Creek.

Jordan River @ 1700 South, Salt Lake City (08/03): 178 cfs, stable. This reading reflects the Jordan River mainstem as it moves through the urban core — a composite signal of Utah Lake outflows, upstream diversions, and municipal return flows. As the Jordan River is the primary surface inflow to Great Salt Lake, current flow volumes are relevant to ongoing GSL elevation monitoring and associated water rights and legislative context.

Little Cottonwood Creek @ Jordan River, near SLC (08/01): 5 cfs, rising. A rising trend at this late-season date warrants attention. Contact Salt Lake City Public Utilities for context on whether this reflects canyon storage releases, localized precipitation response, or gauge variability.
