Raymill Road water level

What this means

Maidenhead Ditch at Raymill Road is running at a record low at −0.02 m.

No reading on record has been lower: the old record low was 0.13 m, from August 24, 2003. The median for mid-October is 0.02 m, based on 21 years of readings, so the river level is 0.05 m below typical. On the same day last year the reading was 0.04 m, a difference of −0.06 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 −0.05 m and 0.00 m.

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