Stream flow, or discharge, is the volume of water that moves over a designated point over a fixed period of time. The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel.
Categories are based on the percentile of existing streamflow record on this day-of-the-year. A streamgage is not ranked when there is less than 20 years of record or a current streamflow measurement is unavailable.

Calendar year -- a 4-digit number representing the actual calendar year of the annual peak streamflow; if columns 21-22 are blank, this field is assumed to be a water year. 21-22: month -- a 2-digit number representing the month of the annual peak streamflow.
For each station, the start of the water year is defined as the month of lowest average monthly streamflow. This definition of water year prevents ambiguity in the direction of computed trends and enables flood and streamflow timing to be described by a normal distribution.

Records from streamflow-gaging stations were analyzed to determine recurrence interval and areal extent of the floods and droughts. Streamflow data are collected, stored, and reported by water year (a water year is the l 2-month period from october l through september 30 and is identified by the calendar year in which it ends).
Weirs increase the change in elevation making the streamflow more consistent which makes flow rate measurements more precise. However, it is very important that all the water in the stream be directed into the weir for it to accurately represent the stream flow. It is also important to keep sediment from building up behind the weir.
