An alternative is to download and open this file:

RUSS data from the MN test lakes

You need a Java-enabled browser to run this applet.

As an alternative you can download and open the
Java Network Launching Protocol (JNLP) file linked above.

More info here.


You can select a different lake from the drop-down list of WOW study lakes.

Click and drag the mouse down and right to zoom in, or drag it up and left to zoom out. Or press the Rescale Plot to fill button to rescale the plot to show all of the current data.

The > and < buttons will advance/retreat to the next/previous profile in the database. The >> and << buttons will automatically move through the data at the rate you set with the DELAY slider.

If you are at the beginning or end of the data, the affected directional buttons will be disabled.

Use the date slider to quickly select a particular date. If there is no data on the date you selected you will get the first profile after that date.

You can select which parameters to plot.

If Clear between plots is not selected, each plot will be drawn over what is already displayed. This can be useful to see the range of values between certain dates. It can also make a big mess. You can clear the graph by changing any of the parameters or the lake (even if you change them back before hitting the Get this Profile button).

Press Get this Profile when you are ready to draw the new plot.

To see the actual data from the profile that is currently showing:

  • Press the Capture this Data button to write the data to the Captured Data Window.
  • Press the Show Captured Data button to view the window.
  • To copy this data to your own file:
    1. Select the data from the data window with your mouse and Copy it (Ctrl-C in Windows)
    2. Paste (Ctrl-V in Windows) it into a text file or spreadsheet.

Here are some tips for saving images of the plots.

About the applet

This program was adapted and extended from Ptplot 2.0 ( which is available under this agreement.

Having Trouble?

The Profile Plotter communicates with our server to send profiles to your computer one-at-a-time. This might be slow if a lot of people are using the applet at once, and it might not work at all if you are behind a firewall that blocks this kind of communication, or if you are using a browser that blocks embedded applets.

Try our new & improved Data Visualization Tools instead. You will get much better performance because the entire datasets are sent to your computer at the start, and no further communication with the server is needed.

Our Java Troubleshooting page might help if you are having any problems with Java.
