No gauge below Knapp Mill is known on the river map.
No gauged tributary joins the Avon above Loddiswell on the river map. Streams without a gauge are not counted here.
No gauge below Loddiswell 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.

320 storm overflows are traced upstream of Netham Weir, the Avon’s lowest gauge on the river map: on the Avon itself, on its gauged tributaries, and on smaller streams that join above there.
Official figures for 2025, for the overflows traced upstream of Netham Weir: 6,019 spills over 34,410 hours in total, across the 317 that have a figure. 3 had no usable monitor data that year.
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 Avon includes the smaller streams that join it there. Where a stretch or a tributary has more than 2, the one discharging now or nearest its gauge is 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.

England's samples only. Each count opens the list of those points, nearest first, with the date of each one’s latest sample (the gauge’s “Upstream of here” list).
FloodRadar does not grade these results: there is no overall score, and official river classifications are a separate dataset. A sample taken downstream of an overflow does not by itself show where anything in it came from. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels.
