  • 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 2025
451822093413201 ALUS-25 033N27W34AAC 01 0000582144
Sand and gravel aquifers (glaciated regions)
Pleistocene Series
LOCATION - Lat 45°18'20.74", long 93°41'18.84" referenced to North American Datum of 1983, in SW 1/4 NE 1/4 NE 1/4 sec.34, T.33 N., R.27 W., Sherburne County, MN, Hydrologic Unit 07010203, The well is located approximately 140 feet southeast of where you will park, directly east of the house by approximately 55 feet.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 30.55 ft. Upper casing diameter 2 in; top of first opening 25.55 ft, bottom of last opening 30.55 ft. The hole for well ALUS-25 was drilled with an 8.25-inch-diameter, hydraulic rotary drill rig, on 08 September 1997 to a depth of 33 feet. The well is constructed of a 5-feet-long, 2-inch-diameter, schedule-40 PVC, 0.010-inch slotted, flush-threaded screen attached to about 25 feet of 2-inch-diameter, schedule-40 PVC casing. The casing stickup was 1.65 feet above land surface on 08 September 1997. The open interval of the well is 25 - 30 feet below land surface and the total well depth is 30.55 feet.
DATUM - Land-surface datum is 920.93 ft above North American Vertical Datum of 1988. Measuring point: top of casing, not protection casing and/or post, 1.65 ft above land-surface datum, Sep. 8, 1997 to present. The current measuring point is a black mark on the top of the PVC well casing (no protection post around casing), which was 1.65 feet above land surface on Sept. 08, 1997. Elevation of that measuring point was 922.58 plus-or-minus 0.03 feet above sea level, North American Vertical Datum of 1988, based on a RTK GPS survey on Sept. 18, 2012.
PERIOD OF RECORD - Water levels are recorded periodically from 08 September 1997 to the present. Hourly water levels were recorded from 11 September 2012 at 09:00 CDT to 04 November 2014 at 09:00 CST.
GAGE -

Continuous water level, water temperature, and battery voltage were measured with an OTT Orpheus Mini 0-4m pressure transducer on Sept. 11, 2012 at 09:00 CDT. These data were recorded hourly by the same OTT Orpheus Mini pressure transducer, which had a datalogger built into it. The datalogger was housed inside of the 2-inch PVC well casing, which has an aluminum locking well cap on top of that. The gage was powered by 3 AA lithium batteries that were inside of the communications rod. Data were downloaded manually and no telemetry or phone line were wired into the gage.

An unheated Onset RG3 tipping-bucket raingage was added to the station on Sept. 11, 2012 at 09:30 CDT. The raingage was mounted on a green T-post, located approximately 590 ft. northwest of well ALUS-25. Additionally, the raingage was located approximately 40 feet southeast of where the homeowner's driveway and County Road 14 meet, in the low ditch area. The raingage had a built-in datalogger, which measured and recorded precipitation quarter-hourly. Raingage is nominally accurate to 0.01 inches.

The pressure transducer and rain gage were removed from the site on Nov. 04, 2014, due to data collection completion for the I-94 Growth Corridor project.

This well is not currently gaged. Only visited periodically to measure discrete groundwater levels and periodically collect discrete water quality samples.

COOPERATION - This site is operated by the U.S. Geological Survey as a monitoring well for the Upper Mississippi (UMIS) National Water-Quality Assessment (NAWQA) program. This well is included in the UMIS NAWQA Agricultural Land-Use Study (ALUS) network. The well was incorporated into the I-94 Growth Corridor Study during August 2012 to November 2014. The I-94 Growth Corridor Study was a collaborative effort between the Minnesota Department of Natural Resources and the U.S. Geological Survey.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - Quarter-hourly precipitation were recorded from 11 September 2012 at 08:30 CDT to 04 November 2014 at 09:30 CST.
INSTRUMENTATION - Precipitation were measured with an Onset RG3 tipping-bucket rain gage, which is accurate to 0.01 inches. The rain gage was unheated and uncovered during the winter. Thus precipitation data during freezing periods (about December through early April) result from melting of snow during warm periods and do NOT represent actual precipitation.
WATER-QUALITY RECORDS
WELL CHARACTERISTICS - Depth 30.55 ft. Upper casing diameter 2 in; top of first opening 25.55 ft, bottom of last opening 30.55 ft.

The I-94 Growth Corridor Study was a collaborative effort between the Minnesota Department of Natural Resources and the U.S. Geological Survey.
INSTRUMENTATION - Water temperature were measured with a OTT Orpheus Mini submersible pressure transducer accurate to +/- 0.1°C. Temperature differences are accurate to 0.1°C.
