Calculation of distance between a point and next downstream point

I am new to Arc Hydro, so I am not sure if there is a tool that does what I'm hoping to accomplish. I have a stream network (an NHD Medium resolution), and two point shapefiles that are snapped to the network. I would like to find the distance along the stream of each point in shapefile 1 to its nearest downstream point in shapefile 2.

My hope is that I would get an attribute column for shapefile 1 that will contain the distances to the nearest downstream point in shapefile 2.

I have searched the forum for a solution to this problem, but have only found several year old posts, none of which seem to accomplish what I have in mind. Anyone have any ideas?
