U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR MARCH 2002 Prepared April 2, 2002 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report varied from deficient in the southeastern region to excessive in the western Adirondack Mountain region. Minimum period-of-record monthly-mean discharges were recorded at Wallkill River at Gardiner and Wappinger Creek near Wappingers Falls. Accumulated stream runoffs at those two sites for the period of October 2001 through March 2002 are about 10 inches below normal. Monthly conditions at these two sites have been deficient during the last six months. Deficient conditions were also evident at most of the sites in the Catskill Mountains while normal streamflows were found in the upper Hudson River and lower Mohawk River basins. The total New York City reservoir system was at 56.8 percent of capacity on March 31; normal for this period is 94.8 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, Cattaraugus Creek at Gowanda, Tonawanda Creek at Batavia, and Oneida Creek at Oneida. Monitored sites at Chenango Forks, Chemung, Salamanca, Wellsville, Garbutt, and Ithaca were in the deficient range. Coram Subdistrict--Summary Report Mean flow at Connetquot Brook near Central Islip was in the deficient range for the fifth consecutive month. The lowest provisional period-of-record minimum monthly mean discharge for March was recorded at this site. ___________________________________________________________________________________________

Provisional Data for March 2002 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 N1259, N1616, Q1249, Sa-1100, S1806, and S1810 have been affected by changes in ground-water withdrawals or sewering.

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.
