USGS Water-Year Summary 2023
462743094025601 WU-335 046N29W18DCDBBA01 Riverton 1 0000241291
Sand and gravel aquifers (glaciated regions)
Glacial Buried Sand and/or Gravel
LOCATION - Lat 46°27'43.24", long 94°02'55.51" referenced to North American Datum of 1983, in SE 1/4 SW 1/4 SE 1/4 sec.18, T.46 N., R.29 W., Crow Wing County, MN, Hydrologic Unit 07010104, The well is located in Riverton, MN. The well is located inside a well house building. The well is located approximately 1.3 miles northwest of the intersection of MN HWY 210 and Co. Rd. 59.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 67 ft. Upper casing diameter undefined; top of first opening undefined, bottom of last opening undefined. Well RT-01 / WU-335 / Riverton 1 is a public supply well that was drilled on an unknown date 1973 with an unknown diameter, with unknown drilling equipment to 67 feet. The well is constructed of a 5-feet-long, unknown-inch-diameter, steel, unknown-inch slotted, unknown material, well screen, attached with to length/s of 6-inch-diameter, schedule 40, steel well casing. According to well inspection record on 18 Feb. 2009, the well is actually constructed of a 6-inch diameter well casing inside of a 12-inch diameter liner. The well casing measuring point (stickup) was 1.61 feet (1218.51 ft. NAVD88, +/- 0.96 ft.) above land surface when measured on 06 Mar. 2020. The open interval of the well is between 55 and 60 feet below land surface and the total well depth (according to well inspection record on 18 Feb. 2009) is 67 feet below land surface.
DATUM - Land-surface datum is 1,216.9 ft above North American Vertical Datum of 1988. Measuring point: Black mark on the side of the 2-inch diameter hole, on top of 12-inch diameter well cap, 1.61 ft above land-surface datum, Mar. 6, 2020 to present. The measuring point is a black mark on the side of the 2-inch diameter access hole, which is located on top of the 12-inch diameter well cap, which was 1.61 feet above land surface on 06 Mar. 2020. Elevation of the measuring point is 1218.51 plus-or-minus 0.96 feet above sea level, North American Vertical Datum of 1988, based on Digital Elevation Model (DEM) data.
PERIOD OF RECORD -

Water levels were recorded periodically from 06 March 2020 to 02 November 2021. Water levels were recorded hourly from 06 March 2020 at 15:00 CST to 28 April 2020 at 15:00 CDT.  Water levels were recorded quarter-hourly from 28 April 2020 at 15:45 CDT to 02 November 2021 at 09:45 CDT, except during the following periods:

28 Apr. 2020 at 15:45 CDT - 05 May 2020 at 05:15 CDT: due to transducer removal during well disinfection process.

GAGE -

Water level and water temperature were measured with a Campbell Scientific, Inc. CS451, 0-33.4 ft. range, submersible pressure transducer nominally accurate to 0.01 feet and 0.1°C, respectively. The submersible pressure transducer was hanging through a 2-inch diameter access hole on top of the well cap. The cable came through the center of a neoprene gasket plug for the 2-inch diameter access hole. Water level, water temperature, shelter temperature, and battery voltage were all recorded by a Campbell Scientific, Inc. CR300 data logger, which records all data quarter-hourly. The data logger was housed in a 14-inch X 16-inch grey fiberglass shelter, which is mounted inside of the well house building, on the east wall. The gage was powered by one 20W solar panel (mounted outside on nearby telephone pole) and a 12v, 18amphr battery. Data were telemetered by a Sierra Wireless RV50X cellular modem with a magnetic mounted Laird TRA6927M3NB-001, Low Profile NMO Antenna, Phantom Shot Glass Style Antenna.

An unheated Texas Electronic Inc. TR-525-I-01 rain gage was added to the station during 28 Apr. 2020 at 15:45 CDT to 02 November 2021 at 09:45 CDT. The rain gage was mounted on a vertical pipe that was attached to top of the well house, and wired into the CR300 datalogger inside the shelter (inside the well house). The datalogger recorded quarter-hourly rainfall data. Rain gage is nominally accurate to 0.01 inches.

All monitoring equipment was removed from the site on 02 Nov. 2021 at 09:45 CDT. This site has been discontinued for the USGS/MDH Pathogens study.

COOPERATION - This site is operated from 06 March 2020 to 02 November 2021 by the U.S. Geological Survey as a public water supply well for the USGS/MDH Automated Virus Sampler Study. The USGS/MDH Automated Virus Sampler study is a collaborative study between the Minnesota Dept. of Health and the U.S. Geological Survey.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - Precipitation data were recorded quarter-hourly from 28 April 2020 at 15:45 CDT to 02 November 2021 at 09:45 CDT.
INSTRUMENTATION - Precipitation was measured with a Texas Electronics TRP-525-I-01 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.
