U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR JANUARY 2001 Prepared February 2, 2001 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. The percent of median flow decreased from December to January at all these sites. Adjustments were made to flows at East Branch Delaware River at Margaretville due to ice effect during the month. Extreme ice conditions were reported for Sacandaga River near Hope, Schoharie Creek at Prattsville, Wallkill River at Gardiner, Wappinger Creek near Wappingers Falls, Beaver Kill at Cooks Falls, West Branch Delaware River at Walton, and Independence River at Donnattsburg, and therefore these sites were not included in this report. 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, Tonawanda Creek at Batavia, and Oatka Creek at Garbutt. Sites at Chenango River at Chenango Forks, Chemung River at Chemung, and Allegheny River at Salamanca were in the deficient range. Genesee River at Wellsville remained in the deficient range for the third consecutive month. All sites were adjusted for backwater from ice. Coram Subdistrict--Summary Report January mean flow at Connetquot Brook near Central Islip was in the normal range. ___________________________________________________________________________________________
