USGS Water Data recorded streamflow on the Willamette River at Portland, Oregon at 16,700 ft³/s as of 2026-10-26, up from 3,820 ft³/s one day prior [^1].

Four other river monitoring sites also registered shifts in flow and gage height over the same 24 hour window.

The Rio Grande at Embudo, New Mexico rose to 1,980 ft³/s from 1,230 ft³/s. Gage height at that location increased to 5.41 ft from 4.35 ft over the period [^2] [^3].

Three sites recorded falling measurements. The Colorado River at Lees Ferry, Arizona fell to 5,580 ft³/s from 7,870 ft³/s [^4]. The Ohio River at Louisville, Kentucky dropped to 28,100 ft³/s from 51,100 ft³/s [^5]. The Duwamish River at Tukwila, Washington recorded streamflow of 903 ft³/s on October 26; the prior day reading at that site was -809 ft³/s [^6]. Gage height at the Duwamish site fell to 6.37 ft from 9.52 ft [^7].

Gage height on the Willamette River at Portland fell to 2.12 ft from 4.64 ft over the period, even as streamflow rose sharply [^8].

No cause for the divergent shifts is stated in the published gauge data.
