According to the non-relativistic theory of the luminiferous aether, the speed of light should be increased or decreased when "dragged" along by the water through the aether frame, dependent upon the direction. According to Stokes' complete aether drag hypothesis, the overall speed of a beam of light should be a simple additive sum of its speed through the water plus the speed of the water.
