Lake Mead currently sits near 1,039 ft, a record low reached in late August 2026 amid the Colorado River basin's prolonged megadrought. U.S. Bureau of Reclamation data show storage at roughly 26-27% of capacity, with recent weekly declines of 0.5 ft driven by below-average snowpack runoff, elevated evaporation from higher temperatures, and sustained downstream deliveries exceeding inflows. The July 2026 24-Month Study's most probable scenario projects 1,037 ft by year-end 2026, while probable minimum runs reach substantially lower levels, aligning with market-implied odds favoring a drop below 1,028 ft. Key resolution thresholds near Tier 3 shortage (1,025 ft) and upcoming winter precipitation forecasts plus post-2026 operating guidelines will shape further movement.

Resolution is determined by the lowest daily elevation recorded at Lake Mead (Hoover Dam, USBR site) between market creation and March 31, 2027. Because a lower reading can occur at any point up to March 31, 2027, all outcomes are settled after the window closes, based on the lowest daily elevation recorded during the window.
The resolution source is the minimum daily lake elevation published by the U.S. Bureau of Reclamation for Lake Mead at Hoover Dam, available at https://data.usbr.gov/catalog/4370/item/6123. USBR data is provisional and subject to revision; the lowest daily elevation reflected in USBR data as of April 15, 2027 governs, and revisions published after April 15, 2027 will not change the outcome. Daily elevation data published at https://lakemead.water-data.com/ may also be referenced, but if it disagrees with USBR, the USBR value governs.
