When I think of flash floods in southern Utah, Paria Canyon/Buckskin first comes to mind.
The average flow this time of year is 10 cu ft/sec., but I'm always thinking high potential for flash flood between mid July to the first week in October so average is irrelevant. With all the rain this week I checked the USGS water data for the Lee's Ferry Gaging Station.
OK, now follow me here The flow is calculated using an algorithm based on the gauge height at that station. According to the posted data on Sept 11 at 19:15 the flow was 460 cu ft/sec, at 19:30 it was 2490 cu ft/sec , 19:45 4480 cu ft/sec , 20:30 6500 cu ft/sec.
From 20:45 - 21:30 the river continued to rise, but the algorithm the USGS is using caps out at gauge height of 11.30ft (equals 6600 cu ft/sec. ) The maximum gauge height was measured 12.66 ft. (see link below for USGS table). The data is provisional, but my guess is when they complete the final calculations the flow will have exceeded 9000 cu ft/sec. If so, this will have been the highest flow since 1958.
I already hiked Paria this past May, but thinking of taking another run at it in early - mid October to see how much the canyon has changed. Anyone interested in joining me?

WOW!!!!! That would have been awesome to see (from a safe place)!!!!!!!!!
