Heavy rainfall across central Indiana in mid-August 2026 produced record or near-record crests on the White River, with National Weather Service and USGS gauges confirming peaks exceeding 20 feet at multiple Indianapolis sites, including 20.51 feet at Raymond Street and 20.02 feet at the Museum of Art. This aligned with upstream records such as 24.93 feet in Anderson and 24.60 feet in Noblesville, driven by saturated soils and prolonged precipitation that elevated river stages well into major flood categories. Trader consensus at 99.5% for over 20 feet reflects these verified observations and the absence of measurement revisions. A narrower peak below the threshold would require substantial downward adjustments to official crest data or a redefined gauge location, both improbable given cross-verified agency reports.
