Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
05427850 YAHARA RIVER AT STATE HIGHWAY 113 AT MADISON, WI
LOCATION - Lat 43°09'03", long 89°24'07" referenced to North American Datum of 1983, in SW 1/4 SW 1/4 sec.23, T.8 N., R.9 E., Dane County, WI, Hydrologic Unit 07090001, at northbound bridge on Highway 113.
DRAINAGE AREA - 114 mi² of which 36.6 mi² probably is noncontributing.
REVISIONS HISTORY - The 2003-2017 water year peak annual streamflow data were previously published as maximum daily mean. The data were revised in 2022 to reflect maximum instantaneous discharge.
SURFACE-WATER RECORDS
PERIOD OF RECORD - January 2002 to current year.
GAGE - Water-stage recorder. Side-looking velocity meter system. Datum of gage is 840.00 ft above NAVD88, from GPS.
REMARKS - Records fair except those for estimated discharges which are poor. For records status prior to October 1, 2013, see remarks printed in annual water-data reports. Gage-height telemeter at station.
EXTREMES FOR PERIOD OF RECORD - Peak of record discharge of 1,700 cfs, 13.17 ft gage height, occurred March 15, 2019.
WATER-QUALITY RECORDS
PERIOD OF RECORD - January 2002 to current year.
PERIOD OF DAILY RECORD - SUSPENDED SEDIMENT DISCHARGE: January 2002 to current year.
TOTAL PHOSPHORUS DISCHARGE: January 2002 to current year.
DISSOLVED ORTHO-PHOSPHORUS DISCHARGE: October 2010 to current year.
INSTRUMENTATION - Refrigerated autosampler since January 2002.
REMARKS - Load records are fair. Samples are point samples unless otherwise noted. Daily loads and concentrations generated using GCLAS (Graphical Constituent Loading Analysis System) using linear interpolation between sample concentrations. For WY2013 and prior, a log-linear interpolation was used.
