DynDOLOD Resources SE contains specifically made dynamic LOD and static LOD models for waterfalls.

For best visuals and performance typically do not install any 3rd party LOD resources - remove them if necessary.

If any of these mods are added or removed, LOD should be generated from scratch.

In case of visual issues or a mod not being on the list, make a post to the official DynDOLOD support forum to request updates or for qualified help and advice.
