Not Thrilled with Results of Watershed Tool

I ran some tools on my mosaicked DEM, got some good preliminary results, but the result of the watershed tool was a value of 1, which gives a map that is one solid color. That's not what you want.

I need to re-run some of the preparatory tools again with different values, see if I come up with any new results. I might not, because the D8 algorithm in ArcMap is fast and efficient of computer resources, but is known to work much better on areas with more relief than I have in my very flat watershed.
