Union Bridge water level

What this means

Low water at Union Bridge: the gauge reads 0.02 m, at a record low.

That is below the previous record low of 0.02 m (September 26, 2006), so the gauge is setting a new low. That puts it 0.07 m below the median of 0.09 m for mid-October, based on 21 years of readings. A year ago it stood at 0.04 m (−0.02 m).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 0.02 m – 0.05 m.

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