Unity Water Brown for Imported Mesh

Hi guys,

So I am trying to use Water Pro to create a river through script. However, when I add the mesh through script to the Water Pro gameobject, the water in the scene will be a shade of brown but will still have reflections (shown below). Has anyone run across this error before or has any idea on how to fix it? I think I've narrowed it down to the default mesh being a child of the WaterPlane Object whereas my mesh is not a child of the object , but I have not figured out a way to replace that mesh with my mesh instead. Also, whenever I manually place the water into the scene, it looks fine but that is not a solution in my project.

Thanks for the help guys
