U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR NOVEMBER 2001 Prepared December 4, 2001 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report in eastern New York were in the deficient range except at sites in the western Adirondack mountains region in northern New York. Mean flows at these sites were in the normal range. Mean flows at Hudson River at Hadley, Mohawk River at Cohoes, Wallkill River at Gardiner, and West Branch Delaware River at Walton were in the deficient range for the fourth consecutive month, at Sacanadaga River near Hope for the third consecutive month, and at Wappinger Creek near Wappingers Falls for the second consecutive month. The second lowest provisional period-of-record minimum monthly mean discharge for November was recorded at the sites at Hope, Gardiner, Wappingers Falls, Margaretville, and Walton. On November 5 the New York State Department of Enivironmental Conservation issued a drought watch for 13 counties in southeastern New York (Cortland, Delaware, Dutchess, Greene, Madison, Orange, Otsego, Putnam, Rockland, Schoharie, Sullivan, Ulster, and Westchester). This is in addition to the drought watch that was issued back on August 24 for Allegany, Broome, Cattaraugus, Chautauqua, Chemung, Chenango, Steuben, and Tioga. Ithaca Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report for western New York were in the deficient range at all sites. Oatka Creek at Garbutt remained deficient for the fifth consecutive month. Coram Subdistrict--Summary Report Mean flow at Connetquot Brook near Central Islip was in the deficient range. New York City reservoirs The New York City reservoir system was at 45.3 percent of capacity on December 3, 2001. Normal for this period is 71.2 percent of capacity. ___________________________________________________________________________________________

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.
