What this means
Low water at Samsjøen ndf.: the gauge reads 0.32 m³/s, below normal for mid-October.
It is 7.40 m³/s below the flood level of 7.73 m³/s. The median for mid-October is 0.84 m³/s, based on 21 years of readings, so the flow is 0.52 m³/s below typical. On the same day last year the reading was 2.18 m³/s, a difference of −1.86 m³/s.
