After that, Daldowie, about 11 km along the river.
No gauge measures South Calder Water 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.

A status says whether an overflow is discharging now, never how much or why. A monitor that is offline or has not reported is not “not discharging”. Sewage in Britain’s rivers →

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 South Calder Water 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.
- No water-sampling point with a banked sample is placed on this stream. Only England’s samples are banked, and only where the map can place their sampling point.
- Nothing on this page says whether any place floods. For an address, see its postcode page.
