Figure 1. Daily mean discharge for water year 2004 compared with percentile distribution of mean daily discharges for the 30-year period, 1961-90, for three representative gaging stations. A
daily-mean discharge is in the deficient-flow range if its value is less than or equal to the 25th percentile, in the normal-flow range if its value is between the 25th and 75th percentiles, and in
the excessive-flow range if its value is equal to or greater than the 75th percentile.
