Recent USGS measurements place Great Salt Lake elevations near 4,189.6–4,189.8 ft in late September 2026, following a record-dry 2025–2026 winter with limited snowpack and runoff. Elevated air temperatures have intensified evaporation while tributary inflows from the Bear, Jordan, and Weber rivers remain below average, sustaining a net water deficit. State conservation measures, including leasing and wetland restoration that delivered hundreds of thousands of acre-feet, have moderated further declines but not offset the imbalance. These conditions position the annual minimum near 4,189.3–4,189.4 ft as the leading market outcome, with traders monitoring updated NOAA precipitation outlooks and USGS daily readings through December for shifts in the final low.
