USGS Water-Year Summary 2023
473429095051303 925C 147N35W02DCBB 03
Sand and gravel aquifers (glaciated regions)
Glacial Surficial Sand and/or Gravel
LOCATION - Lat 47°34'28.87", long 95°05'14.38" referenced to North American Datum of 1983, in NW 1/4 SW 1/4 SE 1/4 sec.02, T.147 N., R.35 W., Beltrami County, MN, Hydrologic Unit 07010101, The well is located approximately 11 miles NW of Bemidji, MN and 2.4 miles SE of Pinewood, MN. 
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 36.28 ft. Upper casing diameter 2.04 in; top of first opening 29.46 ft, bottom of last opening 34.46 ft. Well 925C is a groundwater observation well that was drilled on 17 Nov. 1983 with a 7.25-inch-diameter, with an unknown drill rig to a unknown borehole depth. The well is constructed of a 5-feet-long, 2.04-inch-diameter, schedule-40, galvanized steel, 0.010-inch slotted, well screen, attached with to length/s of 2.04-inch-diameter, schedule-40 galvanized steel well casing. The well casing measuring point (stickup) was 3.54 feet (1423.58 ft. NAVD88, +/- 0.01 ft.) above land surface when measured on 17 Nov. 1983. The open interval of the well is between 29.46 and 34.46 feet below land surface and the total well depth is 36.28 feet below land surface.
DATUM - Land-surface datum is 1,420.04 ft above North American Vertical Datum of 1988. Measuring point: Undefined, 3.54 ft above land-surface datum, Nov. 17, 1983 to present. Water levels are in depth below land surface and feet above sea level. Water levels are accurate to within 0.01 feet below land surface. Water-level elevations are accurate to plus-or-minus 0.01 feet, based on differential GPS Survey on Oct. 26, 2010. Water-level differences are accurate to plus-or-minus 0.001 feet.
PERIOD OF RECORD - Water levels were recorded periodically from 27 February 1984 to the present. Water levels were recorded hourly during 12 May 2011 at 10:00 CDT to 10 April 2012 at 09:00 CDT.
GAGE - This well is not currently gaged. Only visited periodically to measure discrete groundwater levels and periodically collect discrete QW samples.

Continuous water level was measured with an OTT Orpheus Mini 0-4m pressure transducer from 12 May 2011 to 10 Apr. 2012. 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 galvanized steel well casing, which has a aluminum locking well cap on top of that. The gage was powered by 3 AA alkaline batteries that were inside of the communications rod. Data was downloaded manually and no telemetry or phone line was wired into the gage. The OTT Orpheus Mini pressure transducer and datalogger were removed from the well on 10 Apr. 2012 due to completion of the study.
COOPERATION - Well 925C is operated in cooperation with the U.S. Geological Survey's Toxic Substances Hydrology Program, Minnesota Pollution Control Agency, Enbridge Energy Inc., and Beltrami County. This well is located at the National Crude-Oil Spill Research Site near Bemidji, Minnesota.
