Stoney Middleton Flooding - Nov 2016

[Rob]

So significant rain fell on Monday 21st Nov all over the country, including the Peak District. The recorded amount varies depending upon which site you use:

Wardlow = 13.5mm

Bamford = 36mm

Buxton = 22.4mm

Sheffield = 40mm

Either way, on my commute back from Chesterfield that evening the roads were wetter than i'd witnessed in 10 years. Most notable was the flooding in Stoney Middleton Dale, with basically a river flowing down it!

From what i could tell the flow was joining the main road in two places, at the bottom of Eyam Dale and at the bottom of the Delph. Beyond (west) of the Delph the road was dry, indicating that Watergrove Sough was not the primary source of the flooding. This video shot a few hours before i was there shows this to be the case:

This morning (thursday 24th) the delph is still flowing out onto the road, although the Eyam Dale flow had stopped by Wednesday morning. Also i think Carlswark bottom entrance had stopped flowing this morning, from what i could tell from the car.

Has anyone been on foot around the area?
Is water sinking in the large sinkhole in the Delph, or has it backed up/collapsed?
Is the tunnel that normally takes the Delph water under the road blocked?

Delph still flowing onto the main road this morning, so one only has to assume that the culvert under the road is blocked.

Anyone been on foot around there yet?

So no Streaks trips then? 

Thanks for the update Rob, any excuse to avoid Stoney caves is welcome.

I wouldn't have thought Streaks will be effected at all, and certainly not the cause of the flow of water down the road, but without someone going to have a look we really have no idea...

We drove past the Delph Saturday morning, around 7.30am, but it didn't seem especially wet then - damp road, but no obvious flow. Don't think it's rained since then though...?

I was bimbling around the Delph a month or so ago, and the culvert was blocked, water spilling out into the road, so I unblocked it  :halo:

Coming back down an hour or so later, the tide had gone down.

Are the road drains linked to the culvert?, because the drain above the culvert was also overflowing before I unblocked the culvert, and had also ceased being a resurgence on my way back.

Flooding in School Lane, Hathersage.

In the 20-odd years I lived there I never saw that.....

Delph finally stopped flowing onto the road last night. Did someone clear the culvert?

Anyone been up the delph yet to see if anything has changed?

Water level in Streaks last night was pretty average. Not particularity high at all

Was up t'Delph in late September and both swallets were as they have always been. Upper Delph has a concreted dam between it and the stream, so unless some 'yoof' has removed it....

Am in SMD today, should have time for a quick shufty after a quick cave.
