Bull Brook

A stream near Newell Green, Bracknell Forest. No gauge of its own: what the river map and the banked data say about it.

Bull Brook is a stream on Ordnance Survey’s river map near Newell Green, Bracknell Forest, with about 5.6 km of mapped channel. On the map it flows into the Cut, which flows on into the River Thames and out to the sea.

Next gauge downstream

Warfield on the Cut, about 600 m along the river below where Bull Brook ends on the map.

After that, Binfield, about 3.9 km along the river.

No gauge measures Bull 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 Bull 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.
