Spatial Join not working

I've got stream reaches and basins. The basins have a mean slope class which I need to transfer to the stream reaches. Some stream reaches are outside the basin feature class, so those reaches need the closest basin's attributes.

Any ideas why the output of my Spatial Join (target features: reaches, join features: basins, join operation JOIN_ONE_TO_ONE, keep all target features: true, match option: closest, search radius: blank, distance field name: blank) turns out like the attached image? Both basins and reaches are colored by slope class.

edit: Could it be something to do with trying to join 20,000 basins to 250,000 stream reaches? Is there a limit to how many shapes are considered in a Spatial Join?
