Water level

History
What this means
The River Bourne at Idmiston is running at a record low at −0.21 m. That reading is from 6 Oct 2026, 10:30 BST, so the gauge may be offline or reporting late.
No reading on record has been lower: the old record low was 0.00 m, from October 11, 2005. The usual range here runs from 0.00 m to 0.60 m.
It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between −0.21 m and −0.08 m.
Autumn rain usually starts to lift rivers again after the summer low.

Fishing and paddling
At low levels, many rivers become a walk-and-paddle trip. Fish hold in deeper pools and spook easily.
Flood alerts and warnings come from the Environment Agency.
