Ideas on making AIAgent avoid water?

Is there a way to bake Navigation so it avoids water?

 

To my knowledge if water is a mesh you should be able to set it's layer in the navmesh baking. Worst case scenarios you can add mesh to the scene the occupy the same area as the water and bake those and then remove them once baked.

 

Hi,
You could consider two routes for this:

If your water is a mesh, add a collider, and add a NavMeshObstacle to it so your agents avoid it.

or:

If your is a plane, or something else, consider creating an empty GameObject and adding some colliders to it in the (rough) shape of your water, then adding a NavMeshObstacle to that.

Kind Regards,

To refine the others' answers a bit, you need to select your water plane, give it an appropriate collider, and open the navigation window. There, navigate to the object tab and you'll see the possibility to set an area type. Simply set your water to a non-walkable surface and you're good to go. No need for NavmeshObstacle components and such.
