WATER-RESOURCES CONDITIONS IN

NEW YORK

FEBRUARY 2000




U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR FEBRUARY 2000 Prepared March 3, 2000 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report in eastern New York were in the normal to excessive range. Adjustments were made to all these sites generally for the first half of the month due to ice effect. Warmer temperatures, rain, and significant snowmelt caused rises in streamflow at the end of February. Extreme ice conditions were reported for Sacandaga River near Hope, Schoharie Creek at Prattsville, and Wallkill River at Gardiner, and therefore these sites were not included in this report. Ithaca Subdistrict--Summary Report Provisional monthly mean discharges increased throughout western New York, but remained in the normal range at Allegheny River at Salamanca, Tonawanda Creek at Batavia, and Oatka Creek at Garbutt. Monthly mean discharges at Susquehanna River at Conklin, Chenango River near Chenango Forks, Chemung River at Chemung, and Genesee River at Wellsville all increased into the excessive range in response to significant snowmelt, caused by above normal temperatures near the end of the month, combined with moderate to heavy amounts of rainfall. Coram Subdistrict--Summary Report Provisional mean flow at Massapequa Creek at Massapequa was in the deficient range for the twelfth consecutive month. ___________________________________________________________________________________________

Water levels in N1259, N1616, Q1249, Sa-1100, S1806, and S1810 have been affected by changes in ground-water withdrawals or sewering.
