GROUNDWATER RECORDS

WELL CHARACTERISTICS - Depth 11.81 ft. Upper casing diameter 2.04 in; top of first opening 6.97 ft, bottom of last opening 11.27 ft. The hole for well E05 was drilled with a hydraulic rotary drill rig, on 20 August 2002 to a depth of 11.81 feet. The well is constructed of a 4.30-feet-long, 2.04-inch-diameter, schedule-40 PVC, 0.010-inch slotted, flush-threaded screen attached to about 6.97 feet of 2.04-inch-diameter, schedule-40 PVC casing. The casing stickup was 1.59 feet above land surface on 20 August 2002. The open interval of the well is 6.97 - 11.27 feet below land surface and the total well depth is 11.81 feet.

DATUM - Land-surface datum is 1,093.01 ft above North American Vertical Datum of 1988. Measuring point: MP is mark on top of casing, NOT protection post, 1.59 ft above land-surface datum, Aug. 20, 2002 to present.

PERIOD OF RECORD -

Daily-average water levels were recorded from Oct. 26, 2002 to May 13, 2003. Hourly water levels were recorded from May 13, 2003 at 11:00 CDT to 23 Oct. 2018 at 18:00 CDT, except during the following periods:

Aug. 03, 2010 at 06:00 CST - Sept. 20, 2010 at 12:00 CDT: due to unplugged comm. cable.

Jul. 04, 2011 at 21:00 CDT - Jul. 12, 2011 at 16:00 CDT: due to transducer thermistor failure.

Aug. 02, 2015 at 06:00 CDT - Apr. 19, 2016 at 18:00 CDT: due to transducer thermistor failure.

Jul. 15, 2017 at 06:00 CDT - Oct. 23, 2018 at 18:00 CDT: due to transducer thermistor failure. 

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

As of 19 April 2016 at 18:43 CDT, data collection for the Glacial Ridge project has ended. Hourly water levels continue to be recorded and semiannual calibration measurements continue to be collected. However, water levels are no longer being corrected or approved.

GAGE -

Water level and water temperature were measured with a Design Analysis H-310 submersible pressure transducer nominally accurate to 0.01 feet and 0.1°C, respectively. A Texas Electronics, Inc. TR-525I, unheated, tipping-bucket rain gage measures precipitation and is nominally accurate to 0.01 inches. Water level, water temperature, precipitation, shelter temperature, and battery voltage are all recorded by a Campbell Scientific, Inc. CR206 data logger, which records all data hourly (except quarter-hourly precipitation). On 19 April 2016 at 18:47 CDT, the datalogger program was updated to record only hourly water level, water temperature, and precipitation (no longer quarter-hourly). The data logger is housed in a 14-inch X 16-inch grey fiberglass shelter attached to the well. The gage is powered by a 10W solar panel and 12v, 12 amphr station battery and is telemetered by radio to telephone telemetry.

The WaterLOG H-310 pressure transducer was removed from the well on 23 Oct. 2018 at 17:25 CDT. This pressure transducer had been failing for awhile. Data collection for the Glacial Ridge hydrology study had concluded in 2016, so failing pressure transducer was removed from the site. There is still a rain gage and datalogger station deployed at the site.

COOPERATION - During 2003-2016, this site was operated as part of a study to understand hydrologic changes resulting from wetland and prairie restoration and climate change. The station was funded in cooperation with the Red Lake Watershed District, the U.S. Fish and Wildlife Service, The Nature Conservancy, and the Environment and Natural Resources Trust Fund.

REMARKS -

As of 19 April 2016 at 18:43 CDT, data collection for the Glacial Ridge project has ended. Hourly water levels continue to be recorded and semiannual calibration measurements continue to be collected. However, water levels are only being corrected and approved as time allows.  Water temperature data were worked and approved during 20 April 2016 - 24 Oct. 2018 in March 2019.

Measured groundwater levels are precise to two decimal places, not the 3 decimal places reported. Differences between subsequent groundwater levels are precise to 3 decimal places, however. Three-decimal place precision is useful at this site for hydrologic analyses such as estimation of groundwater recharge and evapotranspiration.

CLIMATOLOGICAL RECORDS

PERIOD OF RECORD -

Precipitation were recorded hourly during Apr. 27, 2003 at 19:00 CDT to 13 Oct. 2015 at 23:00 CDT, except during the following periods:

Aug. 03, 2010 at 06:00 CDT - Sept. 20, 2010 at 14:00 CDT: due to unplugged comm. cable.

Jul. 19, 2014 at – 20 Aug. 2014: due to rain gage multiplier unknowingly resetting to 0.0000

Jul. 08, 2018 at 10:00 CDT to Oct. 23, 2018 at 17:00 CDT: due to funnel blowing off rain gage.

When possible, missing precipitation daily-sums (above) were accurately estimated based on precipitation records from the nearby Glacial Ridge Project rain gages.

Precipitation was corrected and approved until Oct. 13, 2015. Precipitation continues to be recorded but raingage maintenance and calibration data collection ceased on Oct. 13, 2015.

INSTRUMENTATION - Precipitation is currently measured with a Texas Electronics TRP-525I tipping-bucket rain gage, which is accurate to 0.01 inches. This rain gage was installed at this site on 12 July 2012. The rain gage is 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. During 27 April 2003 to 12 July 2012, precipitation was measured with a Texas Electronics, Inc. 10.3-inch TR-6118-1L tipping-bucket rain gage accurate to 0.01 inch. The rain gage is 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.

REMARKS - Precipitation was corrected and approved until Oct. 13, 2015. Thereafter, precipitation continues to be recorded but raingage maintenance and calibration data collection has ceased.
