Rules
This market will resolve according to the lowest gage height (river level), in feet, recorded at the Mississippi River at St. Louis, MO streamgage (USGS site 07010000) between market creation and November 30, 2026, as published by the United States Geological Survey (USGS) for parameter code 00065 under statistic code 30800.
- Exactly one outcome in this market will resolve to "Yes".
- The lowest daily reading in the window decides this market; the level does not need to be sustained.
- If USGS does not publish a reading for one or more days, this market will resolve according to the lowest reading among the days that are published.
- Values will be used exactly as published by USGS, without rounding.
- USGS reports gage height at this gage to 2 decimal places.
