The lake retention time for a body of water with the volume 2,000 m 3 (71,000 cu ft) and the exit flow of 100 m 3 /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.
The residence time of a fluid parcel is the total time that the parcel has spent inside a control volume (e.g.: a chemical reactor, a lake, a human body).The residence time of a set of parcels is quantified in terms of the frequency distribution of the residence time in the set, which is known as residence time distribution (RTD), or in terms of its average, known as mean residence time.
[6] [10] It is the southernmost, shallowest, and smallest by volume of the Great Lakes [11] [12] and also has the shortest average water residence time. At its deepest point, Lake Erie is 210 feet (64 m) deep, making it the only Great Lake whose deepest point is above sea level. [13]

The water residence time for the lake is roughly 3 years. The majority of the water drains into the Susquehanna River, however evapotranspiration and loss to groundwater occurs but has not been measured as of 2017. Most substances that dissolve in the lake eventually leave the lake with the flow, with some serving as nutrients for organisms ...

At its northern end is the city of Coeur d'Alene. It spans 25 miles (40 km) in length and ranges from 1 to 3 miles (5 km) wide with over ...
The lake water is estimated to have been sealed off under the thick ice sheet about 15 million years ago. [8] Initially, it was thought that the same water had made up the lake since the time of its formation, giving a residence time in the order of one million years. [26]
