What this means

The Environment Agency has the River Clyst Tributary at Clyst St Mary Millstream Outfall at 1.50 m. There is no published reference for this river yet, so we can't say whether that is high or low for the season.

It has barely moved over the past 24 hours. The 30-day range is 1.50 m – 1.51 m.

The agency publishes no normal range for this gauge yet, so we show the trend only. How to read levels

For anglers and canoeists

Without a reference range, compare today with the chart: a sharp rise usually means coloured water.

Many angling and canoe clubs check gauges like this one before heading out.
