Resolution rules

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 does not fall below 3,510.00 feet. Otherwise, this market resolves "No." 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. In the case that the Resolution Source publishes data, sufficient to settle a Market, that is clearly erroneous and the result of technical or operational error, or of unauthorized interference with the Resolution Source or its data, the Market may remain open for a period of up to seven (7) calendar days (ET) from the time of the original release, in anticipation of a correction by the Resolution Source. If the Resolution Source publishes a corrected value within that period, that value will be eligible for resolution. If no corrected value is published within that period, Polymarket will issue a Clarification to determine whether the originally published value may be eligible for resolution, or whether other action is required to preserve the orderly functioning of the Market.

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.
