Information on the spatial and temporal distribution of water resources in Finland is published through the Hydrology Interface. Observations are made on elements of the hydrological cycle (harvest, evaporation, flow and run-off), water quantity (water level of water bodies) and other hydrological phenomena (snow water value, ice thickness, water temperature, etc.). The total number of observed or calculated values is approximately 5000 measurement points or ranges.
