Page 3 - DEFINITION OF TERMS. The volume of water flowing in a stream — the "run-off" or "discharge" — is expressed in various terms, each of which has become associated with a certain class of work. These terms may be divided into two groups: (1) Those which represent a rate of flow, as secondfeet, gallons per minute, miner's inches, and...
Page 5 - States gallons equals 3.07 acre-feet. 1,000,000 cubic feet equals 22.95 acre-feet. 1 acre-foot equals 325,850 gallons. 1 inch deep on 1 square mile equals 2,323,200 cubic feet. 1 inch deep on 1 square mile equals 0.0737 second-foot per year. 1 foot equals 0.3048 meter. 1 mile equals 1.60935 kilometers.

As the gage height is the mean for the day it does not indicate correctly the stage when the water surface was at crest height, and the corresponding discharge was consequently larger than given in the maximum column. Likewise, in the column headed "Minimum" the quantity given is the mean flow for the day when the mean gage height was lowest. The column headed "Mean" is the average flow in cubic feet for each second during the month.
