Obtaining stream flow direction

Greetings,

I have a polyline stream layer (shapefile) and I want to know if there is a way to find the cardinal flow direction  (N, NE, E, SE, S...) of each individual stream segment?  I have a DEM, but I am not interested in the terrain flow direction that water would normally flow. I am looking to find the cardinal flow direction of the stream(s) segments themselves. My ultimate goal is to determine the average stream flow direction within a polygon layer using a spatial join.

I am not sure if this matters, but I have From_Nodes and To_Nodes, reach codes and distances in my attribute table.

I hope this makes sense.

Any and all information, tools, tips, tricks is greatly appreciated.

Thanks....

Mark
