Just spent the weekend up at Bob Scott’s Bothy and touring the area to see what damage has been done by Monday’s flood (August 11th).
Started off on Saturday morning fording the Derry Burn, where the bridge has been swept aside, and going through Glen Luibeg and over to Corrour Bothy in Glen Dee (where I had to burn and remove an astonishing amount of rubbish – a tale for another day). The bridge at Luibeg is fine, but the ford, which I normally use, isn’t possible with dry feet any more because a crucial boulder has been moved.
(6.9.14 update: There is a large tree across the Derry Burn about 200 metres up from the broken bridge. Care is required, but this can be used as an alternative to wading the burn.)
Then I went up over MacDui, battling fierce winds which had me down on my hands and knees several times, hanging on to boulders, and down past Loch Etchachan into Coire Etchachan and down Glen Derry, where most of the damage seemed to be concentrated.
On Sunday I went through Clais Fhearnaig into Glen Quoich and had a look up as far as the ford, which has totally changed its configuration and again was not possible dry-shod. A shallower alternative looked possible a few yards upstream but as this involved wading through newly flooded heather I’m not sure it would be any dryer. I did intend walking down to see where a change in the course of the River Quoich had cut through the landrover track but I think it must be down near the bottom of the glen and, quite frankly, I was exhausted after my fight with the wind on Saturday and just didn’t have the energy.
So without any further ado, here’s the photos…
The tide mark high up the river bank is clearly visible in this shot taken just above the Black Bridge. The bridge is intact, but the tide marks and debris there show it was very close to being overwhelmed.
The stream coming out of Clais Fhearnaig totally overwhelmed the bridge over the twin concrete culverts. Much of the road was washed away and you can see from the vegetation and gravel how large the flow was.
Some of the flood debris on the flats around Bob Scott’s Bothy. The bothy was completely surrounded by fast flowing water but was undamaged. A sandbank upstream from the bothy has now disappeared, but there is a new gravel bank where we normally get water beside the bothy.
The landrover track leading to the ford beside Derry Lodge to the Luibeg Cottage side of the river has been washed out.
The Derry Burn footbridge. The bank at the other side was washed away and the bridge swung round onto the east bank. The burn is fordable at several points but this could be difficult or even impossible in times of spate

This tidemark across the road beside the Mountain Rescue Post shows the extent of the flooding. The river runs just this side of the two further away trees but, at its height, it was lapping at the doors of the hut.
Stepping stones across the Luibeg Burn have been swept away. You can still get two thirds of the way across dry-shod, but it’s one boulder short of a complete crossing. The bridge half a km upstream is intact.

The large, tightly jammed boulders which formed the stepping stones across the Glas Allt Mhor in Glen Derry have been washed away. Crossing is still possible just a yard or two downstream.
The Glen Derry footpath about half a kilometre north of the Derry Dam footbridge, buried deeply under gravel washout from a normally unremarkable burn. A huge quantity of gravel and mud has been washed down across the hillside over about 10 or 15 metres of track.

The east pier of the Derry Dam footbridge, showing the extent to which it is now undercut. I understand the estate has had an engineer examine this and that it is considered safe for the present.

And a face on view from the west bank
This burn used to flow gently across the path, with a few stepping stones. Now the water has not only cut a channel through the path but shattered about a foot of bedrock
Another cut-out through the Derry path, this one barely a kilometre north of the Lodge
And in case you were wondering how deep that had cut – here’s my walking pole
Even small paths have been affected. Much of the path from Clais Fhearnaig down to Glen Quoich has been washed out

For comparison, this photo was taken at the same ford a couple of years ago. (Note the snazzy pink wellies!)
