Spratton Brook (Hollowell Arm) (Spratton Brook)

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

Spratton Brook (Hollowell Arm) (Spratton Brook) is a stream on Ordnance Survey’s river map near Hollowell, West Northamptonshire, with about 16 km of mapped channel. On the map it flows into the River Nene; beyond that the map has a gap, so where it goes next is not known.

No gauge measures Spratton Brook (Hollowell Arm) (Spratton Brook) 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.

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 Spratton Brook (Hollowell Arm) (Spratton Brook) itself, so its own level is not known here.
Storm overflows are listed only where the river map places them on this stream; an overflow it could not place is not counted.
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.
