Click to hide Water-Year Summary instructions and information
  • 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 2023
450814094315001 LFO1-B Litchfield Far Nest 0000773062
Sand and gravel aquifers (glaciated regions)
Glacial Surficial Sand and/or Gravel
LOCATION - Lat 45°08'14", long 94°31'50" referenced to North American Datum of 1983, in sec.11, T.119 N., R.31 W., Meeker County, MN, Hydrologic Unit 07010204, The well is located approximately 0.26 miles SE of the City of Litchfield's Water Treatment Plant. The well is located in an open mowed-grass area on the north side of a city park. The well is located approximately 0.23 miles SW of the intersection of MN HWY 12 and 270th street.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 25.27 ft. Upper casing diameter 1.2 in; top of first opening 22.4 ft, bottom of last opening 25.06 ft. The hole for well LFO1-B was drilled with an 8.25-inch-diameter, hollow stem auger drill rig to a depth of 25.5 feet. The well is constructed of a 2.66-feet-long, 1.25-inch-diameter, schedule-80 PVC, 0.010-inch slotted Environmental Manufacturing Inc. well screen, attached with glued PVC couplings with length/s of 10.00 feet of 1.25-inch-diameter, schedule-80 PVC well casing. The well casing measuring point (stickup) was 2.42 feet (1117.64 ft. NAVD88, +/- 0.1 ft.) above land surface when measured on 12 June 2015. The open interval of the well is between 22.40 and 25.06 feet below land surface and the total well depth is 25.27 feet below land surface.

This well is screened in the unconfined aquifer, which is the shallow aquifer above the confining unit above where nearby city wells pump from a confined aquifer.

Jewetts Creek is located approximately 200 ft. SW of this well. The water level in this surficial well is likely highly influenced by the water level of nearby Jewetts Creek.
DATUM - Land-surface datum is 1,115.22 ft above North American Vertical Datum of 1988. Measuring point: White mark on top of grey 1.25-inch PVC well casing, not top of steel protection post, 2.42 ft above land-surface datum, Jun. 12, 2015 to present. The measuring point is a white mark on the top of the grey PVC 1.25-inch well casing, which was 2.42 feet above land surface on 12 June 2015. Elevation of the measuring point is 1117.64 plus-or-minus 0.1 feet above sea level, North American Vertical Datum of 1988, based on differential GPS and optical survey on 28 September 2015.
PERIOD OF RECORD - Water levels were recorded periodically from 04 August 2015 to 24 April 2017. Water levels were recorded hourly from 09 December 2015 at 13:00 CST to 24 April 2017 at 16:00 CDT, except during the following periods:

26 Apr. 2016 at 08:00 CDT: due to transducer removal during well purge
09 May 2016 at 12:00 & 13:00 CDT: due to transducer removal during water sampling

When possible, missing daily-average water levels (above) were accurately estimated based on the trend of the hydrograph during these periods.
GAGE - Continuous water level, water temperature, and battery voltage are measured with an OTT Orpheus Mini 0-10m pressure transducer. These data are recorded hourly by the same OTT Orpheus Mini pressure transducer, which has a data logger built into it. The data logger is housed inside of the 1.25-inch PVC well casing, which has an aluminum locking well cap on top the 6-inch black steel protection post. The gage is powered by 3 AA lithium batteries that are inside of the data logger communications rod. Data is downloaded manually and no telemetry or phone line is wired into the gage.

The pressure transducer and data logger were removed from the well on 24 April 2017 at 16:52 CDT. Data collection for the Confining Beds "phase 1" study have concluded and all data logging equipment have been removed from the sites.
COOPERATION - This site was operated (2015-2017) by the U.S. Geological Survey as a monitoring well for the Glacial Confining Beds Study. The well began to be used as part of the Glacial Confining Beds Study immediately after installation on 12 June 2015. The Confining Beds Study is a collaborative effort between the Environment and Natural Resources Trust Fund, Iowa State University, Minnesota Geological Survey, and the U.S. Geological Survey.
