South Cerney water level

What this means

Low water at South Cerney: the gauge reads 0.27 m, at a record low.

That is below the previous record low of 0.30 m (December 10, 2011), so the gauge is setting a new low. The median for mid-October is 0.41 m, based on 21 years of readings, so the river level is 0.14 m below typical. On the same day last year the reading was 0.32 m, a difference of −0.05 m.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 0.27 m – 0.33 m.

Autumn rain usually starts to lift rivers again after the summer low.
