Scott texted me that at 9:30AM Jim saw 21 inches on the physical gage at D and that it was rising. You can see the rise curve on the USGS gage and correlate pretty well from that.
Follow up is that Jim saw the gage level out and it is still 21 inches at noon. Me thinks that the 24 hour rule will take effect and it will shoot up this evening, given almost an inch overnight in Farmington.
