Live levels from 2 monitoring stations across Gloucestershire, updated every 15 minutes.
| Station | Level now | Status |
|---|---|---|
| Merestones Road | 0.01 mASD 1h ago | Low |
These gauges are filed under the Hatherley Brook, but the river map places them on another watercourse, so they are not in Hatherley Brook’s order above.
| Sandhurston Broadboard Brook | 0.71 mASD 15d ago | old reading | ||
| Downstream of Merestones Road, 13.2 km by river. | ||||
Stations are listed from source to mouth as the water flows, traced on the river map (OS Open Rivers) and the Environment Agency’s own links between its gauges. A distance “by river” is along the river, and is shown only where the map traces the path.

Streams and rivers with a gauge whose water joins Hatherley Brook above one of its gauges, from the source down. Named streams without a gauge that have a page here are listed at the end.
No gauged tributary joins Hatherley Brook above Merestones Road on the river map. Streams without a gauge are not counted here.
Below Merestones Road, its water next reaches Sandhurst, a gauge on Broadboard Brook, 13.2 km by river downstream.
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.

None of the storm overflows FloodRadar holds is traced upstream of Merestones Road on the river map. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
2 other overflows within 3 km of these gauges are placed below Hatherley Brook’s lowest gauge or on another river, so not listed.
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.

Dated samples taken by the Environment Agency, not live readings. Results are published days to months after the sample is taken, and many points are sampled only a few times a year, or have not been sampled for years.
11 sampling points on the Hatherley Brook and the streams that join it above Merestones Road, and below it. 1 has a sample from the last 12 months; 2 have any sample banked. Listed from the source down, grouped by the next gauge each one's water reaches.

Distances are along the river to the gauge named. England's samples only.
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.
