Whittle Brook

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

Whittle Brook is a stream on Ordnance Survey’s river map near Birch, Rochdale, with about 5.5 km of mapped channel. On the map it flows into Hollins Brook, which flows on into the River Roch, then the River Irwell; beyond that the map has a gap, so where it goes next is not known.

Next gauge downstream

Blackford Bridge on the River Roch, about 2.7 km along the river below where Whittle Brook ends on the map.

After that, Pioneer Mills, about 5.1 km along the river.

No gauge measures Whittle 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 Whittle Brook 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.
