That is how long the crest took to reach Coyote Creek above Hwy 237 at Milpitas from Coyote Creek near Gilroy, measured peak to peak on the discharge record. For anyone living at the bottom of the creek it is also how much warning the water itself gave.

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.

3 of the 8 stations on this reach have no reading in this window. Each carries the dates out of its own USGS site record underneath, so a reader can tell a hole in the federal network from a hole in this build without taking our word for it.
