This market resolves "Yes" if the lowest daily elevation recorded at Lake Mead (Hoover Dam, USBR site) between market creation and March 31, 2027 falls below 1,033.00 feet but does not fall below 1,028.00 feet. Otherwise, this market resolves "No." 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.
