I'm planning to be at the narrows on 2026/05/29.

If I'm there, resolves NO if I try to hike it but can't due to flooding, resolves YES if I'm able to hike it.

If I don't end up going in that day, or fail to hike for reasons unrelated to flooding, resolves to whether https://waterdata.usgs.gov/monitoring-location/USGS-09405500/#period=P7D&dataTypeId=continuous-00060-0&showMedian=true&showFieldMeasurements=true

is above 150cfs on that day.
