Of course, the main influence on streamflow is precipitation runoff in the watershed. Rainfall causes rivers to rise, and a river can even rise if it only rains very far up in the watershed-remember that water that falls in a watershed will eventually drain by the outflow point.
One US gallon of water weighs 133.526464 ounces. The calculations for that answer are below: 1 gallon = 8.345404 pounds 1 pound = 16 ounces 8.345404 X 16 = 133.526464.
How many ounces are in a glass of water? The density and specific gravity of water varies depending on the temperature of the water. At 32 degrees Fahrenheit, when water is cold enough to freeze, the specific weight of the water is 8.34 pounds per gallon, so 16 ounces of water weighs 1.05 pounds.
