I have posted some new Landsat scenes from May 3, 2011. These scenes follow the Wabash River. Interestingly, there are clouds in the scenes but most of the flooding is in the area that is essentially cloud free. These images can be downloaded here:

An overview of the Landsat scene covering the Lafayette Area is shown below:

You can clearly see the extent of the flooding from this zoomed in view below:

To view an image which high lights the flooding, I use channels 6, 4 and 3 as red, green and blue. I also used a gaussian stretch for the data (as apposed to a linear stretch that I usually use) because of the clouds in the scene.
