Station where readings are taken for one or several of the following elements for river, lake and reservoir waters: head, discharge, transport and depositing of materials, temperature and other physical water properties, ice cover characteristics and chemical properties of water. The HYDRO Bank recognises three statuses for the stations:
A station is hydrologically significant when it measures the outflow from a waterway which comes from an upstream river basin or a spring.
A station is hydrologically insignificant when it measures outflow from an industrial canal, an irrigation channel, the branch of a waterway, or a diversion canal.
A station is a trial station when it is created by a producer for its own usage, for training or simulation purposes.
