U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR JUNE 2000 Prepared July 6, 2000 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report in eastern New York were in the excessive range except at Sacandaga River near Hope, Independence River at Donnattsburg, and West Branch Oswegatchie River near Harrisville. Mean flows at these 3 sites were in the normal range. As in the past 2 months, precipita- tion was above normal in the Capital Region for June (6.69 in., normal = 3.62 in.) and for the year to date (25.94 in., normal = 17.58 in.). The percent of median flow increased (over 100%) from May to June at all sites included herein except at those in northeastern New York which showed a decrease. Precipitation during a storm June 6-7 in the Capital Region and surrounding counties ranged from over 2 inches in Warren County to more than 6 inches in Greene County. A new provisional period of record maximum monthly mean discharge for June was recorded at Schoharie Creek at Prattsville (96 years/1,240 cfs - previous=1,230 cfs) and East Branch Delaware River at Margaretville (63 years/589 cfs - previous=556 cfs). Also, a new provisional maximum daily discharge for June (53,500 cfs - previous=50,900 cfs) for the period of record (82 years) was reported for Mohawk River at Cohoes. Conditions were in the excessive range for the fourth consecutive month at Hudson River at Hadley and fifth consecutive month at West Branch Delaware River at Walton. Ithaca Subdistrict--Summary Report Provisional mean monthly flows at all monitored sites included in this report in western New York were in the excessive range, except for Allegheny River at Salamanca which was at the high end of the normal range. Flows at Susquehanna River at Conklin remained in the excessive range for the fifth consecutive month, while flows at Oatka Creek at Garbutt, Chenango River near Chenango Forks, and Tonawanda Creek at Batavia continued in the exces- sive range for the second consecutive month. Flows at Chemung River at Chemung and Genesee River at Wellsville rose into the excessive range for the first time since February 2000.

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