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
423954089071501 DISCOVERY FARMS CORE WATERWAY 1 NR JANESVILLE, WI
LOCATION - Lat 42°39'53.9", long 89°07'14.9" referenced to North American Datum of 1983, in SE 1/4 NW 1/4 sec.6, T.2 N., R.12 E., Rock County, WI, Hydrologic Unit 07090001,
DRAINAGE AREA - 0.01 mi², 9.4 acres (estimated by Discovery Farms personnel)
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2014 to current year.
GAGE - Water-stage recorder. Water levels are controlled by 1.5 ft H flume. Elevation of gage is 861 ft above NAVD88, from topographic map.
REMARKS - Records are good, except for estimated days which are fair. Note that discharge is the daily sum, in cubic feet.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - October 2014 to current year.
INSTRUMENTATION - Rain Gage: A Design Analysis H-340 SDI 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 2” pipe, approximately 6 feet above ground. Data are retrieved via a 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. This particular rain gage can compensate for intense precipitation events, and output ranges from 0.009 per tip for low-intensity events up to ~0.014 per tip for intense events.
EXTREMES FOR PERIOD OF RECORD - Max daily precip: 2.21 in., Sep 17, 2015.
REMARKS - Precipitation.-- Data are recorded to the nearest minute in the datalogger. Rainfall estimated to be 0.00 on Nov. 29, Dec. 22, Jan. 3, 16-17, 28, Feb. 7, Mar 2-3, 7, and 23 because recorded precipitation was interpreted as collector snowmelt. Daily values estimated for Oct. 1 – 27 from NWS station at Afton, WI, USC00470045.
Remarks.--Records are good except for estimated days, which are fair. All unit values and daily values are stored in ADAPS.
WATER-QUALITY RECORDS
PERIOD OF RECORD - October 2014 to current year.
INSTRUMENTATION - Water-quality sampler since October 2014.
REMARKS - Chemical analyses by the Water and Environmental Analysis Lab at the University of Wisconsin-Stevens Point. Samples with end dates/times are flow-composite samples collected by an automatic point sampler which represent the event-mean concentration for the specified runoff period. Samples with only start dates/times are discrete samples collected by the same sampler. The sample runoff volume (Parm Code 72243) is the total flow that occurs between the start and end time of each flow-composite sample. Some runoff events were not sampled. An approximate storm load (in pounds) can be computed by multiplying the sample runoff volume (in cubic feet) by the constituent concentration (in mg/L) and a factor of 6.2428x10^-5.
