Hi ypshzms, you didn't say whether you were using Lumion 3 or 2.5, so I have assumed that you are using 2.5.
Water in Lumion rely on projected reflections.
Projected reflections use on a single 360 degree panoramic reflection texture which is projected onto all reflective materials. The projected reflection method is only an approximation and will never provide 100% realistic reflections.
Add the Lights -> Utilities -> Reflection control
object to your scene to specify the position where the 360 degree panoramic reflection texture should be rendered at.
If you do not add this object to your scene it will be placed a few hundred meters above the terrain by default.
If you are rendering interiors, the best position for the Reflection Control
object is often near the camera position. Bear in mind that you can also animate this object with the Basic Animation/Advanced Animation
effects in the Movie
