USGS Water-Year Summary 2023

450437092181901 DISCOVERY FARMS-WILLOW WATERWAY 3 NEAR EMERALD, WI

LOCATION - Lat 45°04'36.8", long 92°18'19.3" referenced to North American Datum of 1983, in NW 1/4 NW 1/4 NE 1/4 sec.22, T.30 N., R.16 W., St. Croix County, WI, Hydrologic Unit 07030005,

DRAINAGE AREA - 0.03 mi², 16.1 acres, from LIDAR.

SURFACE-WATER RECORDS

PERIOD OF RECORD - August 2013 to September 2015.

GAGE - Water-stage recorder. Water levels are controlled by 2.5 ft H flume.

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 - August 2013 to September 2015.

INSTRUMENTATION - Tipping bucket rain gage with electronic datalogger.

EXTREMES FOR PERIOD OF RECORD - Maximum daily rainfall, 2.77 in., Aug. 18, 2015.

REMARKS - Records are considered good, except for estimated days, which are poor, and other periods as noted below. WY2014 Data are recorded to the nearest 1 minute in the datalogger. Rainfall estimated to be 0.00 for Dec. 3-4, 27-28, Jan. 8, 19-20, Feb. 18, 20-21, Mar. 9-10, 20-21, 28-30, and Apr. 3-5 because recorded precipitation was interpreted as collector snowmelt. Remarks.--Records are good except for estimated days, which are poor. All unit values and daily values are stored in ADAPS. WY2015 Data are recorded to the nearest 1 minute in the datalogger. Rainfall estimated to be 0.00 for Nov. 22, 29, Dec. 8, 23-24, Jan. 15, 17, 26, Mar. 23, 25, 30 because recorded precipitation was interpreted as collector snowmelt.

WATER-QUALITY RECORDS

PERIOD OF RECORD - August 2013 to September 2015.

INSTRUMENTATION - Water-quality sampler since August 2013.

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 is the total flow that occurs between the start and end time of each flow-composite sample. In most cases, the sample runoff volume is slightly less than the total storm runoff volume. 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.
