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.
Oddly enough, I am often asked how much a gallon of water weighs. Iâve heard guesses anywhere from 5 pounds to 15 pounds. How much does a gallon of water really weigh? The simple answer is that a gallon of water weighs about 8.3 pounds. However, this answer comes with a caveat. Someone trying to be smart with you (or just taking the question literally) may tell you that itâs a trick question that has no answer the way it was asked.
