USGS Water-Year Summary 2019
LOCATION - Lat 39°50'52.2", long 83°09'26.4" referenced to North American Datum of 1983, Franklin County, OH, Hydrologic Unit 05060001, on right downstream side of State Route 665 bridge, 2.5 mi upstream from mouth, 2.7 mi north-northwest of Harrisburg and 1.5 mi east of Darbydale.
DRAINAGE AREA - 35.8 mi².
PERIOD OF RECORD - October 1992 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 811.50 ft (NAVD 1988); previously described as: "Elevation of gage is 813 ft above sea level (from topographic map). Prior to Sept. 2001 at site 1.5 mi downstream at datum of 785 ft."

Discharge records fair for 2014, except for estimated records, which are poor. Sept. 12, 2014 to Nov. 24, 2014: discharge records fair. Nov. 24, 2014 to Mar. 25, 2015: discharge records fair, except for estimated records, which are poor. Mar. 25, 2015 to May 27, 2015: discharge records good. May 27, 2015 to July 23, 2015: discharge records good, except for estimated records, which are poor. July 23, 2015 to November 9, 2015: discharge records good. November 9, 2015 to November 2, 2016: discharge records good, except for estimated records, which are poor. Nov. 3, 2016 to Mar. 20, 2017: discharge records good except for periods of estimated discharge, which are poor. Mar. 21, 2017 to Nov. 19, 2017: discharge records good. Nov. 20, 2017 to Dec. 26, 2017: discharge records fair. Dec. 27, 2017 to Jun. 5, 2018, 2018: discharge records poor.  Jun. 6, 2018 to Oct. 17, 2018: discharge records fair except for periods of estimated discharge, which are poor. Water-quality data collected at this site.

Record quality ratings will not be included in the water-year summary for approved records newer than 09/30/2019. Record quality is still being rated internally. For questions about record quality ratings, please send email to gs-w-oh_NWISWeb_Data_Inquiries@usgs.gov.

PERIOD OF RECORD - May 1992 to current year.
INSTRUMENTATION - Refrigerated water-quality pumping sampler since October 1992.
REMARKS - Water-quality and suspended-sediment samples were collected by equal-width-increment (EWI) sampling method, approximately once per month. Suspended-sediment samples and seasonal-event water-quality samples were collected by pumping sampler. Pumped samples were collected for every 0.5-ft change in stage, and on every fifth day if the stage did not change 0.5 ft during the preceding five-day period. Sediment samples were also collected at a single vertical, approximately biweekly. Suspended-sediment loads were calculated using the mean-interval method (Porterfield, George, 1972, Computation of Fluvial-Sediment Discharge: U.S. Geological Survey, Techniques of Water-Resources Investigations, book 3, chap. C3, 66 p.). For days with unsteady concentration, discharge, or both, the day was subdivided into quarter-hour intervals and the daily load was calculated by summing the loads for these quarter-hour intervals. This required interpolation between measured and estimated concentrations.
EXTREMES FOR PERIOD OF DAILY RECORD - SEDIMENT CONCENTRATIONS: Maximum daily mean, 819 mg/L, June 29, 1998, minimum daily mean, 0.0 mg/L, on many days during 2009 - 2012, October 2014, on several days during 2004 and 2008, December 18 - 22, 2005, and August 14 and 15, 2007. SEDIMENT LOADS: Maximum daily, 4,420 tons, June 29, 1998, minimum daily, 0.00 ton, on many days during 1993 - 1995, 1998, 1999, 2002, 2007 - 2013, on several days during 1996, 1997, 2000, and 2004 - 2006, September 27 - 30, 2014, October and November 2014.
EXTREMES FOR CURRENT YEAR - SEDIMENT CONCENTRATIONS: Maximum daily mean, 372 mg/L, Mar. 21, minimum daily mean, 2 mg/L, Sept. 9-14. SEDIMENT LOADS: Maximum daily, 334 tons, May 22, minimum daily, 0.01 ton, September 11-12, 28-30.
