CORPS FLOOD TUTOR

Good Afternoon,

In Grass4.1 /src.contrib/CORPS there is a tutorial with elevation and
lake data for the Mississippi/Missouri Flood I think. I would like to
know how I can access this?

I've tried creating the region suggested in the elevation raster file but
apparently the State Plane zone = 0 is in Error ?

Has anyone looked at this contributed data from /CORPS ? If so how ?

Any help would be appreciated.
