49 storm overflows are traced upstream of Killermont, the Kelvin’s lowest gauge on the river map: on the Kelvin itself, on its gauged tributaries, and on smaller streams that join above there.

Official figures for 2025, for the overflows traced upstream of Killermont: 2,519 overflow events over 2,860 hours in total, across the 24 that have a figure. 3 had no data that year; 22 have no 2025 figure. Scottish Water counts overflow events, not the 12/24-hour spills counted in England and Wales, so this total cannot be set beside theirs.
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 Kelvin includes the smaller streams that join it there. Where a stretch or a tributary has more than 4, the 3 discharging now or nearest its gauge are listed, the rest are counted, and every one is in that gauge’s “Upstream of here” list.

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.
