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.
Best Answer: You cannot say because gallon is a liquid measure and pound is a weight measure. A gallon of water would weight about 8,3 pounds, a lot more than a gallon of gas that would be around 6 pounds. So if itÂ´s water 5 gallon would weight 41,5 pounds and if gas, would be around 30 pounds.Source(s):or water, a pints a pound, 8 pints in a gallon, 5 gallons is 40 pounds.
