Above average precipitation was recorded for October for most areas with the bulk of that falling during the last week of the month. Flood watches were issued October 29 for some mid- and southeastern counties due to heavy rains and because of the saturated ground from previous rains.

The total New York City reservoir system was at 101.8 percent of capacity on October 30; normal for this period is 69.2 percent of capacity. Ithaca Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report for October for western New York were in the excessive range in the Susquehanna River, Chemung River, and Allegheny River basins.

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.
