Hydrological monitoring aims produce real time information of water level and discharge, ice thickness including freeze-up and break-up in winter from a network of monitoring stations. Monitoring data is utilized in water resource planning, water management and flood damage prevention. Monitoring is coordinated by Finnish Environmental Institute (SYKE).
This is a National Implementation Plan (NIP) project

- Samples/specimens archived in specimen banks?
- Specimen banking information
Automatic stations and dedicated observers measure water level, discharge or ice thickness.
Methods & Procedures
- Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.
The ice thickness measurement site is located at a distance of at least 50 m from the shore. The measuring devices are a cm-divided measurement stick and, at most stations, three snow ice staffs. For each measurement time, three new drill holes are made at previously undisturbed places. The variables measured are:
- ice (the total thickness of ice, including the blue ice, the snow ice and the water layers between ice layers)
- water (the water level measured from the lower surface of the ice)
- snow ice (the thickness of snow ice)
- snow (the thickness of the snow layer on the ice)
- staff (the thickness of snow ice read at the snow ice staffs)
The usual dates for ice thickness measurements are the 10th, 20th and 30th of each month. The longest records have their beginnings in the 1910's. The present standard of measurements was in the 1970's.
