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.

the junction of Spring Harbor Drive and University Avenue in Madison.
DRAINAGE AREA - 3.29 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - February 1976 to current year.
GAGE - Water-stage recorder, crest-stage gage, and concrete control. Datum of gage is 855.1 ft above NAVD of 1988.
REMARKS - Record is considered Fair below about 50cfs and poor otherwise. For records status prior to October 1, 2013, see remarks printed in annual water-data reports. Gage-height telemeter at station.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - Tipping bucket rain gage June 26, 2019 to present.
INSTRUMENTATION - A TR-525USW Tipping Bucket Rain Gage (8.00” funnel diameter) is used with a Campbell Scientific CR10 datalogger to record rainfall in increments of ~0.01 inches. The rain gage is mounted on the top of the shelter, approximately 15 feet above ground. The record starts 6/27/2019. Data are retrieved via a cellular modem. The rain gage is not heated, and is not covered in the winter, therefore snowfall that melts in the funnel is interpreted as snowmelt and is removed from the record.
REMARKS - Remarks.--Records are good except for estimated days, which are fair. For the 2019 water year, record considered fair from 6/27/19-9/5/19 due to periods of estimation and the level adjustment made during the calibration site visit on 8/12. Record considered good from 9/6/19-10/9/19.
WATER-QUALITY RECORDS
PERIOD OF RECORD - February 1976 to current year.
PERIOD OF DAILY RECORD - SUSPENDED-SEDIMENT DISCHARGE: Oct. 1991 to current year; CHLORIDE DISCHARGE: Feb. 2014 to current year; TOTAL PHOSPHORUS DISCHARGE: Jun. 2015 to current year; TOTAL KJELDAHL NITROGEN DISCHARGE: Jun. 2015 to current year; SUSPENDED SOLIDS DISCHARGE: Jun. 2015 to current year.
INSTRUMENTATION - Water-quality autosampler since Feb. 1976.
REMARKS - Records good. Samples are point samples unless otherwise indicated. 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.
