Nice shot. My thought is to darken the water in the ruts a bit (ala muddy water) and let the spraying water alone. If that doesn't work to your satisfaction you might try a noise layer on the spray with selective brushing back the noise on a mask. The truly elegant solution is to cover some of the spray with a lens flare something like what's in the upper left corner. I might even try to drop a dark cloud over the top part of the image and work a rainbow into the area between the spray and the cloud.
