U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR JANUARY 1999 Prepared February 2, 1999 Troy Subdistrict--Summary Report Provisional mean flows in eastern New York ranged from normal to excessive at all sites monitored and included in this report. Moderate rainfall and melting snow caused streams to rise considerably during January 19-20 and 24-25 and the percent of median flow increased over 70% from December to January at all sites included herein. Mean flow at Mohawk River at Cohoes was in the normal range after 5 consecutive months in the deficient range. Ice conditions were reported for part of the month for Schoharie Creek at Prattsville, Beaver Kill at Cooks Falls, Wappinger Creek near Wappingers Falls, and West Branch Oswegatchie River near Harrisville and as a result, the mean flow and percent of median were estimated. Extreme ice conditions were reported for Wallkill River at Gardiner and therefore this site was not included in this report. Ithaca Subdistrict--Summary Report Provisional mean flows for the month of January throughout western New York ranged from normal to excessive at all sites monitored and included in this report. Moderate rainfall and rapid snowmelt, caused by unseasonably warm temperatures, increased streamflow from the deficient range into the excessive range at Susquehanna River at Conklin, Allegheny River at Salamanca, and Tonawanda Creek at Batavia. All other monitored sites rose from the deficient range into the normal range. Coram Subdistrict--Summary Report Provisional mean flow at Massapequa Creek for the month of January was in the normal range for the first time since July 1998.
