About Operational and Research Data Sets

In the context of Great Lakes water level and hydro-climate data, 'Operational' data sets are officially sanctioned by the Coordinating Committee on Great Lakes Basic Hydraulic and Hydrologic Data, an ad hoc advisory group consisting of science agencies from both countries. The operational seasonal forecast, for example, is the monthly coordinated forecast produced jointly by the Army Corps of Engineers and Environment Canada.
