Lake retention time information


The lake retention time for a body of water with the volume 2,000 m3 (71,000 cu ft) and the exit flow of 100 m3/h (3,500 cu ft/h) is 20 hours.

Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake. At its simplest, this figure is the result of dividing the lake volume by the flow in or out of the lake. It roughly expresses the amount of time taken for a substance introduced into a lake to flow out of it again. The retention time is particularly important where downstream flooding or pollutants are concerned.
