USGS Water-Year Summary 2023
433531092263901 NPR-5 North Drain Site Perimeter
Sand and gravel aquifers (glaciated regions)
Pleistocene Series
LOCATION - Lat 43°35'31.04", long 92°26'38.59" referenced to North American Datum of 1983, in NW 1/4 SW 1/4 sec.31, T.102 N., R.13 W., Fillmore County, MN, Hydrologic Unit 07060002, The piezometer is located approximately 1.75 miles SW of Ostrander, MN. The piezometer is located along the perimeter/edge of an agricultural field. The piezometer is located approximately 0.4 miles NE of the intersection of 160 street and Mower/Fillmore County Line Road.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 16 ft. Upper casing diameter 1.57 in; top of first opening 3.38 ft, bottom of last opening 15.31 ft. Piezometer NPR-4 was installed using several sections of 3.25-inch-diameter Geoprobe rods to a depth of 16.0 feet. The piezometer is constructed of a 9.46-feet-long, 1.5-inch-diameter, schedule-40 PVC, 0.010-inch slotted Hole Products Inc. well screen, flush threaded to length/s of 5.00 feet of 1.5-inch-diameter, schedule-40 PVC well casing. The piezometer casing measuring point (stickup) was 1.66 feet (1335.81 ft. NAVD88, +/- 0.05 ft.) above land surface when measured on 14 June 2016. The open interval of the piezometer is between 3.36 and 12.82 feet below land surface and the total well depth is 15.89 feet below land surface.

This piezometer is screened in glacial till/clay sediment, which is overlies bedrock.
DATUM - Land-surface datum is 1,346.8 ft above North American Vertical Datum of 1988. Measuring point: Black mark on top of PVC well casing, 3.84 ft above land-surface datum, Apr. 22, 2016 to present. The measuring point is a black mark on the top of the white PVC 1.5-inch diameter well casing, which was 3.84 feet above land surface on 22 April 2016. Elevation of the measuring point is 1350.64 plus-or-minus 0.05 feet above sea level, North American Vertical Datum of 1988, based on differential GPS survey on 20 August 2016.
PERIOD OF RECORD -

Water levels were recorded periodically from 16 June 2016 to 29 October 2018. Water levels were recorded hourly from 17 June 2016 at 12:00 CDT to 11 April 2017 at 15:00 CDT. Water levels were recorded quarter-hourly from 11 April 2017 at 15:45 CDT to 29 October 2018 at 11:30 CDT, except during the following periods:

01 Nov. 2017 at 14:30-19:00 CDT: due to transducer not recording data after replacing batteries.

17 Jun. 2018 at 10:00 CDT - 21 Jun. 2018 at 04:30 CDT: due to transducer recording inaccurate data for unknown reason.

GAGE - Continuous water level, water temperature, and battery voltage were measured with a previously-used OTT Orpheus Mini 0-10m pressure transducer. These data were recorded hourly from 17 June 2016 at 12:00 CDT to 11 April 2017 at 15:00 CDT by the same OTT Orpheus Mini pressure transducer, which had a data logger built into it. Water level, water temperature, and battery voltage data were recorded quarter-hourly from 11 April 2017 at 15:45 CDT to 29 October 2018 at 11:30 CDT by the same OTT Orpheus Mini pressure transducer, which had a data logger built into it. The data logger was housed inside the 1.5-inch PVC well casing and inside an attached 4-inch PVC shelter. Both the piezometer and shelter have a slip-on PVC cap and no pad lock. The gage was powered by 3 AA alkaline batteries that were inside of the data logger communications rod. Data were downloaded manually and no telemetry or phone line was wired into the gage.

The pressure transducer and data logger were removed from the well on 29 Oct. 2018 at 11:30 CDT. Data collection for the Impacts on Drainage Recharge study have concluded and all data logging equipment have been removed from the site.
COOPERATION - This site was operated (2016-2018) by the U.S. Geological Survey as a monitoring piezometer for the Southeast Minnesota Subsurface Drainage Impacts on Groundwater Recharge study. The piezometer began to be used as part of the Southeast Minnesota Subsurface Drainage Impacts on Groundwater Recharge study during 13 Jun. 2016 to 29 Oct. 2018. The GW Drainage Recharge study is a collaborative effort between the Environment and Natural Resources Trust Fund (via Legislative-Citizen Commission on Minnesota Resources (LCCMR)) and the U.S. Geological Survey.
