## Reference period is 1978-2000 ** Excessive # Note: Flow statistics based on data collected through November 30, 2003. NOTES, DEFINITIONS, ETC. Percent exceedence is, for example, the percentage of November monthly mean discharges for period of record equal to or greater than the current November monthly mean discharge. Statistics for the "Index Streamflow Stations" table are for the 30-year reference period 1971-2000. All other statistics used in report are based on the period of record at the site. Median = 50th percentile, which means that, for the period of record included in the analysis, 50% of the values are greater than the median and 50% are less. Deficient range = values below the 25th percentile - for the period of record included in the analysis, 75% of the values are greater and 25% are less than this value. Excessive range = values above the 75th percentile - for the period of record included in the analysis, 25% of the values are greater and 75% are less than this value. Normal range = values between the 25th and 75th percentiles.
