Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
It can be thought of as a list of the biggest rivers on Earth, measured by a specific metric. For context, the volume of an Olympic-size swimming pool is 2,500 m 3 (88,000 cu ft). The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second.
This article lists lakes with a water volume of more than 100 km 3, ranked by volume. The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration. Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.
Nominal volume Capacity The total volume of all water held behind a dam at the maximum level possible. Initial volume Design volume The possible volume within the reservoir after it first opens. Many rivers are high in silt that over time deposits behind a dam reducing capacity. Active volume Live volume The total capacity minus the dead pool ...
The Inga falls, whose status as a true waterfall is controversial, are currently incorporated into the Inga I and Inga II hydroelectric facilities. The volume of the river diverted is approximately 30% of the average discharge. The Grand Inga Dam, potentially the world's largest by generating capacity, is also proposed to be built on the falls.

The system that moves water around the Earth is off balance for the first time in human history. Laura Paddison, CNN. October 16, 2024 at 6:00 PM. ... (just over 1,000 gallons) a day to lead a ...
In hydrology, discharge is the volumetric flow rate (volume per time, in units of m 3 /h or ft 3 /h) of a stream.It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m 2 or ft 2). [1]
