So, you don't care about the line appearing interacting with the water column, just with it interacting with the surfaces in the scene?
You could either slap a shader pass on EVERY surface in the scene that the laser line can fall upon, OR do a second render pass (possibly reading the Z-buffer) to apply the laser line effect. Which of these seems more feasible to you based on the preconditions and restrictions of your existing app and scene graph architecture?
