Lake Superior Streams - intensive site data

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 April 18, 2008):

All of the sondes are back in the streams.

We are having some communication
problems with the Kingsbury Creek data logger.

Amity Creek (2002 - present)
	Real Time Data and Water Chemistry Data
	Data Visualization Tool (DVT): Current Year 2007 \| 2006 \| 2005 \| 2002 - 2004 (flow & precip. only) (takes several seconds to load)
	Manually collected physical and chemical data 2002 - Present
Chester Creek (2002 - present)
	Real Time Data and Water Chemistry Data
	Data Visualization Tool (DVT): Current Year 2007 \| 2006 \| 2005 \| 2004 \| 2003 \| 2002 (takes several seconds to load)

Miller Creek
	We are in the process of adapting continuous ice-free season flow data from Miller Creek from several years at several sites to our plotting data visualization tool. Additional, manually collected physical and chemical data will also eventually be posted.

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.

4. 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 now 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.
