About this gauge
Dolní Sytová is a gauge on the Jizera in Czechia.
It lies at 50.6245° N, 15.4411° E.
Its readings come from the Czech Hydrometeorological Institute (CHMI).
The gauge reads the height of the water above a fixed zero, not the depth of the river.
Readings since 1 January 2026: too short a record for a normal range for the date or for records that mean much.
CHMI publishes its 10-minute readings as current data that it has not validated yet.
The newest reading is provisional: the source may still correct it.
