River Calder — Derwent West Cumbria and Duddon
No gauged tributary joins the Calder above Calder Hall on the river map. Streams without a gauge are not counted here.
Where the Calder goes
No gauge below Calder Hall is known on the river map.
Tributaries and where they join are traced on the river map (OS Open Rivers, edition 2026-04) and the Environment Agency’s links between its gauges. The map holds distances between gauges, not the junctions themselves, so a junction is placed between two gauges, and no further up than the tributary’s own lowest gauge.

River Calder — Aire and Calder
Streams without a gauge
Named streams on the river map that flow into the Calder and have no gauge of their own. Each has a page with what is known about it: the next gauge downstream, and any storm overflows or water-sampling points placed on it.
River Calder — Ribble Douglas and Crossens

Storm overflows upstream
River Calder — Aire and Calder
287 storm overflows are traced upstream of Methley, the Calder’s lowest gauge on the river map: on the Calder itself, on its gauged tributaries, and on smaller streams that join above there.
- 0 report discharging now
- 277 not discharging
- 10 offline or silent: 3 monitor offline, 4 status unknown, 3 no live feed
Official figures for 2025, for the overflows traced upstream of Methley: 8,105 spills over 43,788 hours in total, across all 287.
Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of the Calder includes the smaller streams that join it there. Every overflow traced is listed here, each stretch in full. Back to the short lists →

A status is the water company’s own monitor: it says whether an overflow is discharging, never how much or why, and a spill does not by itself explain a change in a river level. A status older than two hours is shown as unknown. Annual figures are the official returns: 12/24-hour spills for England and Wales, overflow events for Scotland (Scottish Water counts differently, so the two cannot be compared). “No data” means the monitor produced no usable data that year, not zero. Overflows are placed on OS Open Rivers (edition 2026-04), which leaves out many small channels: an overflow the map cannot place may still drain here.
