No travel time can be read from this window. The peaks at the top and the bottom of Coyote Creek fall a week apart, which means they belong to different storms in the same sequence rather than to one crest moving downstream.

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.

With the script off this reads as a still frame at the peak of the storm. The peaks table below carries the same readings as text, which is the accessible equivalent of everything the clock shows.
Coyote Creek near Gilroy peak 9,290 cfs

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.

+168.50 h
These peaks are 7.0 days apart, which is a later storm in the same window rather than the same crest arriving.
Coyote Creek at Madrone
+162.00 h
These peaks are 6.8 days apart, which is a later storm in the same window rather than the same crest arriving.

This station peaked before the upstream station did, so the two peaks are separate events.
