  • 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
465735092504901 UNNAMED STREAM AT HWY 29 NEAR FLOODWOOD, MN
LOCATION - Lat 46°57'35.33", long 92°50'48.7" referenced to North American Datum of 1983, in sec.26, T.52 N., R.20 W., St. Louis County, MN, Hydrologic Unit 04010201,
SURFACE-WATER RECORDS
PERIOD OF RECORD -

Gage height and streamflow were measured periodically from Sept. 12, 2019 to the Apr. 16, 2021.

Gage height was recorded quarter-hourly from April 14, 2020 at 17:15 CDT to October 30, 2020 at 14:00 CDT, except during the following periods:

Small & large gaps during 03 Jun. 2020 - 13 Oct. 2020 due to stage sensor coming out-of-water (dry) during low-flow conditions.

GAGE -

This is a discrete WQ sampling and streamflow site.

Continuous water level, water temperature, and battery voltage were measured with a previously-used OTT Orpheus Mini 0-10m pressure transducer. These data were recorded quarter-hourly from April 14, 2020 at 17:15 CDT to August 18, 2021 at 09:00 CDT by the same OTT Orpheus Mini pressure transducer, which had a data logger built into it. The data logger was hung from the top of 4-inch diameter PVC pipe, which is attached to 1-inch diameter PVC pipe that runs into the stream. The pressure transducer was powered by 3 AA lithium batteries that were inside of the data logger communications rod. Data were downloaded manually and no telemetry or phone line was wired into the gage.

The pressure transducer intake frequently comes out-of-water during low-flow conditions, which creates many gaps in the stage and water temperature datasets. Pressure transducer is deployed at an elevation just above the bottom of the streambed in the small channel. 

On 30 Oct. 2020, the OTT Orpheus Mini pressure transducer was temporarily removed from the site during the winter ice conditions. This is a seasonal stage and water temperature site. The transducer will be redeployed in Spring 2021.

Stage and water temperature data collected during 29 Mar. 2021 - 18 Aug. 2021 were not worked/approved due to the site being dry for an extended period. These unapproved data were not needed to for the St. Louis River Peatland Restoration / Mercury (GLRI) study.

All monitoring equipment was removed from the site on 18 Aug. 2021 at 09:00 CDT. This site has been discontinued for the St. Louis River Peatland Restoration / Mercury (GLRI) study. RM3 was removed from the site on 03 Nov. 2021.

COOPERATION - This site was operated (2019-2021) by the U.S. Geological Survey as a discrete water-quality sampling, discrete streamflow, and continuous stage, and continuous water temperature site for the USGS St. Louis River Peatland Restoration / Mercury (GLRI) study. The USGS St. Louis River Peatland Restoration / Mercury (GLRI) study was a collaborative study between the Fond du Lac Band of Lake Superior Chippewa (FDL) and the U.S. Geological Survey.
REMARKS - NOTE: During Sept. 17, 2019 to Apr. 13, 2021, gage height data were measured from RM1. Beginning on Apr. 14, 2020, gage height data were measured from RM2. This change causes a shift in the gage height record beginning on Apr. 14, 2020.
WATER-QUALITY RECORDS
PERIOD OF RECORD -

Discrete water-quality samples were collected periodically from September 12, 2019 to April 16, 2021.

Water temperature was recorded quarter-hourly from April 14, 2020 at 17:15 CDT to October 30, 2020 at 14:00 CDT, except during the following periods:

Small & large gaps during 03 Jun. 2020 - 13 Oct. 2020 due to thermistor coming out-of-water (dry) during low-flow conditions.

COOPERATION - This site was operated (2019-2021) by the U.S. Geological Survey as a discrete water-quality sampling, discrete streamflow, and continuous stage, and continuous water temperature site for the USGS St. Louis River Peatland Restoration / Mercury (GLRI) study.
