Recent Bureau of Reclamation 24-month studies and operational adjustments, including upstream releases from Flaming Gorge Reservoir and reduced Glen Canyon Dam outflows, form the main driver behind the 45.5% implied probability for Lake Powell remaining above 3,510 feet. Persistent drought, record-low 2026 snowpack, and resulting inflows near 29–52% of average have pushed current elevation to approximately 3,519 feet, nearing prior lows, yet these targeted actions aim to stabilize storage and avert drops toward the 3,490-foot minimum power pool threshold. Model consensus shows modest further decline through fall without intervention, supporting trader focus on near-term management over deeper long-term depletion scenarios.

Resolution is determined by the lowest daily elevation recorded at Lake Powell (Glen Canyon 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 Powell at Glen Canyon Dam, available at https://data.usbr.gov/catalog/2362/item/508. 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://lakepowell.water-data.com/ may also be referenced, but if it disagrees with USBR, the USBR value governs.
