My flowlines all go uphill, why?

I have created a set of flowlines using the Fill, Flow Direction, Flow Accumulation, and Reclass tools (in that order) from the spatial analyst toolbox in 10.3.1. I then converted them to polylines from the original raster data. When I looked at my flow directions in the vector data, they were all going uphill. I would like some help trying to figure out what I did wrong. Thank you.
