Hydrometric Observations

Updated 2012-08-28

To provide for the collection, interpretation, and dissemination of surface water quantity data and information and services that are vital to meet a wide range of water management, engineering and environmental needs across Canada. Main gaps: The current hydrometric network is deficient in terms of understanding the regional hydrology and river regimes across Canada. The map below integrates Environment Canada’s two key frameworks: the National Drainage Area Framework with the National Terrestrial Ecological Framework to identify network deficiencies. In order to have sufficient information there needs to be at least one active hydrometric station measuring natural flow in each corresponding ecodistrict within a sub-sub drainage area. This strategy ensures that there will be sufficient information to understand the hydrological processes and the interrelationships with the landscape. This information is essential for research and enhancing our predictive capabilities and data transfer. As the map shows, areas of sufficiency are concentrated in the southern, more populated regions of the country. Network sufficiency declines to the north and northeast, with great extents of northern Canada having no coverage at all. Network type: in-situ.water level and streamflow monitoring stations
