    Resolution criteria

    This market resolves "Yes" if the lowest daily elevation recorded at Lake Powell (Glen Canyon Dam, USBR site) between market creation and March 31, 2027 falls below 3,490.00 feet. Otherwise, this market resolves "No." For reference, 3,490 feet is the minimum power pool elevation below which Glen Canyon Dam can no longer generate hydroelectric power. 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.
