Recirculation rate = Amount of recirculated
water as a percent of intake. The same water can leave a sub-system and re-enter
it or is used in another sub-system many times, resulting in a recirculation
rate > 100%.
Gross water use = Intake + Recirculation.
Consumption = Intake - Discharge.
Consumption rate = Consumption as a percentage
of Intake.
As of 2007, data for the Great Lakes drainage
region, the Ottawa drainage region and the St. Lawrence drainage region are
combined under the Great Lakes drainage region.
