Current Data from Intensive Monitoring Streams

Maps, graphs and charts can be viewed by selecting a stream (above) or by visiting the Data Availability Tables for Duluth Area streams, North Shore streams, or South Shore streams.


Datalogger Status (as of January 6, 2014):

  • Lake Superior: The LLO buoys have been removed for the winter.
  • St Louis River: The USGS station in Scanlon is reporting. The downstream sondes have been removed for the winter. USGS gage height and velocity data are still being reported at the lift bridge site.
  • Duluth Streams:
    • Amity, Chester, Kingsbury, Tischer -- sondes have been removed for the season. They will be returned to the streams when it is possible- hopefully before the spring melt.
    • Miller -- the sonde was not deployed this season.

Options for Viewing Current Data

1. Animated graphs of stream monitoring unit data can be viewed and manipulated with the Data Visualization Tool (DVT).



2. Data collected with stream monitoring units including temperature, turbidity, electrical conductivity and water depth (Real Time Data) is available in both HTML tables and Excel tables.

3. Water Chemistry Data for water samples collected periodically by DuluthStreams staff including nitrogen, phosphorus, pH, and more is available in Excel tables.

Excel chart4. Real time data viewed in Excel can be easily graphed using a simple Excel graphing utility. (choose real time data, then choose Excel format)


The 2002-2005 data posted has undergone QA/QC review. Real time data sensors can, and do, at times produce unexplainable and erroneous data, and periods of missing data. In addition, calibration periods are also captured in the data stream. This data has been removed or adjusted according to the QA/QC protocol. Explainable data problems encountered included: missing data due to transmission problems, erroneous depth readings due to blocked vent tubes, turbidity spikes due to the mechanical sensor wiper malfunctioning, increasing turbidity baseline values due to sensor fouling, and captured calibration periods.
