DRAINAGE AREA - 13.4 mi².
PERIOD OF RECORD - Continuous-record discharge station, April 2004 to current year. No record collected from Sep 10, 2009 through May 17, 2010 due to lake being drawn down for dam maintenance.
GAGE - Water-stage and precipitation recorder with telemetry, crest-stage gage and concrete dam. Datum of gage is 129.9 above NGVD of 1929.
REMARKS - Records fair, except for estimated discharges, which are poor.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of July 23, 1945 reached a discharge of approximately 1,300 ft³/s (as reported by New Jersey State Water Policy Commission; dam failed, discharge may have been greater). Flood of September 16, 1999 reached a peak discharge of 5,730 ft³/s (based on slope-area computation upstream of Grand Avenue, 0.5 mi upstream from gage, adjusted for change in drainage area).
