Nothing crested here. The highest flow anywhere on Coyote Creek in these ten days was under 20 cubic feet per second, which is the creek doing what it does for most of the year.
Mar 2026 event (most recent significant at harvest time; window auto-adjusts if the peak sits at an edge). USGS instantaneous record, 2026-03-12 to 2026-03-22, 6 of 14 requested stations returning data. Retrieved July 28, 2026 at 5:32 PM PT.

8 stations top to bottom, drawn on the 5 with a record in this window. Run the clock and the rise arrives at each in turn. Every column holds the last reading the gauge actually took rather than sliding between samples, so what moves on screen is the record itself.

Discharge in cubic feet per second, from the USGS instantaneous record. Every station shares one axis, so the fall from the top of the creek to the bottom is measured rather than drawn. This window is plotted at reduced resolution by taking the highest reading in each interval at its own timestamp, so no peak is lost and no plotted point is a value the gauge did not report.Where each station's highest reported reading falls inside this storm window. Position is timestamp, not estimated travel.

Peak to Peak
Each interval below is the arrival of the highest reading at that station, measured from the highest reading at Coyote Creek near Gilroy, the furthest upstream station with a record here. An interval is quoted as a travel time only when the downstream peak follows the upstream one inside 48 hours. The rest are still published, with the reason, because an unexplained negative lag on a flood page reads as a broken site rather than as a second storm.
