river outlines from DEM?

Hi, 

is there a way to extract the outline of the river from a DEM? I've already run the fill, flow direction, and flow accumulation tools but i'm not sure how to create the outline. any help would be appreciated. thanks!

i did look at those documents and i tried making a stream but it didnt make an outline of the river. it make a bunch some lines that looked like the river outline but other places it completely missed or would run a line through the river
