Flash Flood In Torrey

We have been having heavy thunderstorms every day for the last week with quite a lot of rain falling, on the evening of Tuesday 24th the rain fell particularly heavily for a couple of hours over the canyon between the Anthill and Thousand Lake Mountain (and over Torrey at the same time). This is the catchment area for Sand Creek which flows down from Thousand Lake Mountain then turns east across the north end of Torrey before joining Sulphur Creek and flowing into Capitol Reef NP. On the map Sand Creek is just to the left of the red line (btw, the map is in metric units, grrr)

The circle right above Torrey is where the pictures around the bridge were taken, the circle to the right is where the dirt road crosses Sulphur Creek and the rectangular area is where the Goosenecks views are. I also went up the road just to the west of Torrey which angles off and crosses Sand Creek but it was raining hard at that point and the creek had overrun the road for about 50 yards with quite deep fast flowing water. I'll return when things calm down a bit.

The bridge is on Center Street which runs up from the side of the Chuck Wagon to the Sleeping Rainbow area behind Torrey, this road was only just paved last year.

Looking west from the bridge, Sand Creek is normally a trickle at this time of year, maybe a couple of feet across and an inch or two deep, even during the snow melt it rarely has more than a foot of water in it.

The water went right up over the bridge.

Walking upstream from the bridge I came across this pipe which is about 3 feet in diameter, the surface was mostly firm - it's not called Sand Creek for nothing!

The pipe had been completely bent downstream, it used to go over the concrete support

Looking downstream, the three pipes on the left are the support for the pipe on the other side of the creek, they are filled with concrete or else would certainly have been washed away too.

The pipe carries the Torrey Canal across Sand Creek, water to the canal has been cut off and it is now just a chocolate coloured stream in the centre of Torrey. Those who have visited will know it as the ditch that flows next to the main road through town. It's used to carry irrigation water from the Fremont River to the local alfalfa fields in the valley, they probably won't miss it while it's raining this much.

The water spread mud and debris over an area about 100 yards wide and a quarter mile long at the bridge including some fields that usually have cows grazing, hopefully they escaped in time.
The whole area in this picture is usually covered in bushes and sage brush.

From here I went down to the Goosenecks viewpoint which overlooks Sulphur Creek deep in its canyon, more rain was falling right over Sand Creek

A few days ago somebody told me that Sulphur Creek was almost dry, now it has the chocolate flood in it

Next I went down my little short cut from the Twin Rocks to the Sinclair Station, this dirt road fords Sulphur Creek just after Sand Creek joins it.

The road comes in right where the picture was taken and out of the river just to the left of the tree in the middle, you can just see the road surface at the top of the bank, the normal sand slope up to it has gone completely.

The bottom of the stream was very soft and the water of unknown depth so I didn't drive across. I walked a little further downstream, the water had been about 5 feet above it's normal surface at this point.

Flash floods are not very common, the one that happened in Bicknell a couple of years ago was the first in that canyon for 50 years they said, no idea when the last one in Sand Creek occurred. Most storms move over too quickly to dump enough rain in a particular area that feeds a small canyon but this one just sat there and poured. I don't know if Sulphur Creek flooded as well upstream of where it joins Sand Creek, when things dry out a little I'll try to take a look on the dirt bike.
