River Ashop

A stream near Edale, Derbyshire. No gauge of its own: what the river map and the banked data say about it.

The River Ashop is a stream on Ordnance Survey’s river map near Edale, Derbyshire, with about 16 km of mapped channel. On the map it flows into the River Derwent, which flows on into the River Trent, then the River Humber and out to the sea.

Next gauge downstream

Yorkshire Bridge on the River Derwent, about 1.8 km along the river below where the River Ashop ends on the map.

After that, Mytham Bridge, about 6.1 km along the river.

No gauge measures the River Ashop itself. A gauge downstream shows water that has already passed it, mixed with everything else that has joined on the way, so it says nothing exact about this stream.

Water-sampling points on the River Ashop

4 Environment Agency sampling points are placed on this stream. These are dated samples taken by hand, not live readings, and FloodRadar does not grade them.

A sample is taken on a date; it says nothing about the water today. A sample below an overflow does not by itself show where anything in it came from.

What this page can and cannot tell you

Its line, its name and where it flows come from Ordnance Survey’s river map (OS Open Rivers, edition 2026-04), which leaves out many small streams, ditches and culverts. “Flows into” is the map’s word: a channel that is not on the map is not shown here, which does not mean it is not there.
No gauge measures the River Ashop itself, so its own level is not known here.
No storm overflow is placed on this stream on the river map. That is not the same as none: the map cannot place every overflow.
Water samples are England’s only (the Environment Agency’s archive), placed where the map can place their sampling point.
Nothing on this page says whether any place floods. For an address, see its postcode page.
