Depth grid files have been added to the downloads directory.  The Readme and Metadata files 
have been updated.

Depth grids for the study area were developed in accordance with the same geographic information 
system procedures and data used to generate the inundation surfaces described in the original 
report.  The inundation surfaces in the report are a flat-surface grid representing only the 
extent of inundation (that is, all depths greater than 0.1).  The depth grids retain the 
differences between the ground-surface and water-surface elevations.

These maps are available at a USGS Web portal at http://wim.usgs.gov/FIMI/FloodInundationMapper.html#. 
Interactive use of the maps by using the mouse cursor to click within the shaded areas can give 
users a general indication of depth of water at any point.
