Harjakoski water level

What this means

The Harjakoski is running far below normal at 54.31 m.

That puts it 0.09 m below the median of 54.40 m for mid-October, based on 21 years of readings. A year ago it stood at 54.41 m (−0.10 m).

It has dropped 0.07 m over the past week. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 54.31 m and 54.53 m.

Early autumn is often low-water season on rivers, until steadier rain returns.
