Event Overview

This market resolves based on the lowest daily elevation recorded at Lake Mead (Hoover Dam) between market creation and March 31, 2027, as published by the U.S. Bureau of Reclamation. See each individual market for its bracket and full resolution terms. 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. 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.
