U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR FEBRUARY 2003 Prepared February 28, 2003 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report in eastern New York were in the normal to deficient range. Adjustments were made to flows at most sites due to ice affect. Extreme ice conditions were reported for nine sites in northern New York and therefore these sites were not included in this report. Although conditions at almost all sites herein decreased from the previous month, only those for Hudson River at Hadley, Wappinger Creek near Wappingers Falls, and East Branch Delaware River at Margaretville were in the deficient range. The total New York City reservoir system was at 90.3 percent of capacity on February 28; normal for this period is 83.4 percent of capacity. Ithaca Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report for western New York were in the normal range at Susquehanna River at Conklin, Unadilla River at Rockdale, Chenango River at Chenango Forks, Chemung River at Chemung, Cattaraugus Creek at Gowanda, Tonawanda Creek at Batavia, Fall Creek at Ithaca, Flint Creek at Phelps, and Oneida Creek at Oneida. Monitored sites at Allegheny River at Salamanca, Genesee River at Wellsville, and Oatka Creek at Garbutt decreased to the deficient range from the previous month. All sites were adjusted for ice. Coram Subdistrict--Summary Report Mean flow at Connetquot Brook near Central Islip was in the normal range. ___________________________________________________________________________________________

Provisional Data for February 2003 INDEX OBSERVATION WELLS The observation-well network generally reflects conditions in water-table sand and gravel aquifers and does not necessarily reflect conditions in confined and bedrock aquifers. Water levels in Sa-1100, and S1810 have been affected by changes in ground-water withdrawals or sewering. Water level in feet below land-surface datum unless site noted with * which indicates reference to sea level or ** which indicates water level in feet above land-surface datum. Statistics used for A-654(replacement) are from A-636, those for Cm-622(replacement) are from Cm-46 (adjusted), and those for U-1619(replacement) are from U-405. NOTE: Review of the long-term record for S8833 has shown historical water-level elevations from Dec. 29, 1988 to Dec. 23, 2002 were in error by 1.05 ft. This discrepancy is due to a change in measuring-point elevation at the well that was not accounted for in the computer record. All water-level data for the period in question has now been corrected accordingly.

## Reference period is 1978-2000 * Deficient. e Estimate # Note: Flow statistics based on data collected through February 28, 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.
