Smallwood Beck

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

Smallwood Beck is a stream on Ordnance Survey’s river map near Lockton, North Yorkshire, with about 280 m of mapped channel. On the map it flows into Crosscliff Beck, which flows on into Black Beck, then the River Derwent, then the River Ouse, then the River Humber and out to the sea.

Next gauge downstream

Mowthorpe Weir Head on the River Derwent, about 13 km along the river below where Smallwood Beck ends on the map.

After that, Forge Valley, about 17 km along the river.

No gauge measures Smallwood Beck 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 Smallwood Beck

1 Environment Agency sampling point is 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 Smallwood Beck 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.
