USGS Water-Year Summary 2024
443920092412702 PI98-12A (middle) 114N16W25BBCB 01 Prairie Is.2 0000612796
Sand and gravel aquifers (glaciated regions)
Pleistocene Series
LOCATION - Lat 44°39'21.92", long 92°41'25.56" referenced to North American Datum of 1983, in SW 1/4 NW 1/4 NW 1/4 sec.25, T.114 N., R.16 W., Goodhue County, MN, Hydrologic Unit 07040001, 5 miles south and 8 miles east of Hastings, Minnesota. The land surface at the site is 689.54 plus-or-minus 5 feet above the North American Vertical Datum of 1988.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 44.12 ft. Upper casing diameter 2 in; top of first opening 39 ft, bottom of last opening 44 ft. The hole for well PI98-12A was drilled with an 8.25-inch-diameter power auger to a depth of 48 feet. The well is constructed of a 4.2-foot-long, 2-inch-diameter, flush-threaded, 10-slot PVC screen, attached to 15.79 feet of 2-inch-diameter, flush-threaded, PVC well casing. This casing stuck up 2.99 feet above land surface on May 18, 2011. The open interval of the well is 39.4 - 43.6 feet below land surface and the well is 44.1 feet deep, according to drilling log. A total well depth of 46.02 feet below land surface was measured on May 18, 2011, and this measurement was updated in GWSI database.
DATUM - Land-surface datum is 686.61 ft above North American Vertical Datum of 1988. Measuring point: MP is mark on casing, not from protection post. MP height is from RP, not LS. RP is 0.14' AL, 2.98 ft above land-surface datum, Nov. 6, 2012 to present.
PERIOD OF RECORD -

Periodic water levels were recorded from Nov. 06, 1998 to May 18, 2011. Hourly water levels were recorded from 6 November 2012 to 06 Jul. 2017 at 18:00 CDT with a pressure transducer and data logger, except during the following periods:

20 June 2015 at 08:00 CDT to 07 July 2015 at 17:00 CDT: due to a failed transducer. 
12 Nov. 2015 at 05:00-08:00 & 12:00-16:00 CST: due to an unknown issue. 
Periodically missing during 26-27 Jul. 2016: due to periodic erroneous water temperature spikes.
19 Nov. 2016 at 17:00 CDT: due to unknown water level spike.
10 Dec. 2016 at 20:00 CDT: due to unknown water level spike.
04 Apr. 2017 at 14:00 CDT: due to unknown water level spike.
08 Apr. 2017 at 05:00 CDT: due to unknown water level spike.
23 May 2017 at 13:00 CDT: due to unknown water level spike.
27 May 2017 at 09:00 & 13:00 CDT: due to unknown water level spike.
29 May 2017 at 01:00 CDT: due to unknown water level spike.
01 Jun. 2017 at 05:00 & 09:00 CDT: due to unknown water level spike.
02 Jun. 2017 at 05:00 CDT: due to unknown water level spike.

When possible, missing daily-average water levels (above) were accurately estimated through 01 July 2016 based on the trend of the hydrograph during these periods.

GAGE -

Water level is measured with a WaterLOG H-3123 submersible pressure transducer accurate to 0.01 feet. Data are recorded by a Campbell Scientific, Inc. CR10 data logger hourly. The data logger is housed in a 14-inch X 16-inch grey fiberglass shelter attached to the antenna mast. The gage is powered by a 20W solar panel and is telemetered by cellular telephone.

The WaterLOG H-3123 pressure transducer was removed from the well on 06 Jul. 2017 at 18:00 CDT. No longer recording continuous WL and WT data in this well. Site has been discontinued from active monitoring network for the Prairie Island Indian Community.

COOPERATION - Well PI98-12A is operated by the U.S. Geological Survey in cooperation with the Prairie Island Indian Community. The monitoring well is part of a network of monitoring wells; used to collect water quality and water quantity data for the Prairie Island Indian Community.

When possible, missing daily-average water temperatures (above) were accurately estimated through 01 July 2016 based on the trend of this well's thermograph and adjacent well PI98-12 & PI98-12B thermographs during these periods.

COOPERATION - Well PI98-12A is operated by the U.S. Geological Survey in cooperation with the Prairie Island Indian Community. The monitoring well is part of a network of monitoring wells; used to collect water quality and water quantity data for the Prairie Island Indian Community.
INSTRUMENTATION - Water temperature is measured with a WaterLOG H-3123 submersible pressure transducer accurate to +/- 1.0°C. Temperature differences are accuate to 0.1°C.
