WSP 1728: Drainage area.
Discharge for the period Oct. 23, 2019 to Nov. 4, 2019, was revised on Oct. 18, 2020, by allowing discharge to be computed instead of estimated, due to a lack of evidence for a reason to estimate the discharges during this time period.
PERIOD OF RECORD.--DAILY GAGE HEIGHT--October 2000 to current year.
Previous locations and datums are as follows:
October 1, 1962 to September 30, 1989, recording gage 1,500 ft. upstream, at datum of 925.55 ft above NGVD29.
