Contents Notes
A 90-year set of lake levels and flows has been developed that reflects a consistent hydraulic regime in the Great Lakes-St. Lawrence River system. This hydraulic regime is defined by the diversion rates into and out of the system, consumptive use withdrawals from the system, the time series of water supplies to the system, outlet conditions of each lake, flow retardation due to ice or weeds in the connecting channels, initial starting elevations for the simulation, the hydraulic condition of the St. Lawrence River, and tidal levels at its outlet. These levels and flows can be used as a reference for assessing the effects of modified lake regulation and climate change.
