extracting values from raster

Hi all,

Its been some years ago since I worked with rasterdata for real, so I have to brush up my knowledge on this subject. Hope you guys is able to help. :)

I have a raster file (img) containing gridcells with values represent floodvalues (0,1 representing 10 cm water on the surface). I want to extract the cells with more than 10 cm water on the surface. I´ve tried with the extract by attributes, but somehow there isn´t a attribute to select?! If I use the info selection on one cell I get the stretched value and the pixel value (which is equel to the amount of water) so there must be a value somewhere that I should be able to extract on.

What am I missing? Can somebody please guide me in the right direction?

Thanks in advance

Christian
