The highest provisional period- of-record monthly-mean discharge for June was recorded at Little Salmon River at Bombay (256 cfs - previous = 244 cfs in 1973, period of record = 1958-95). As of June 13, the New York State Department of Environmental Conservation drought watch and warning had been lifted for most of upstate New York.

Ithaca Subdistrict--Summary Report Above average precipitation for the month of June kept all monitored sites included in this report for western New York in the excessive range for the second consecutive month.

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

## Reference period is 1978-2000 * Deficient @ June 23-30 e Estimate ** Excessive # Note: Flow statistics based on data collected through June 30, 2002. NOTES, DEFINITIONS, ETC. 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.
