I'm not saying the lens isn't sharp, just that the shutter speed required to give the water a smooth texture also affected the leafs of the trees because of the wind

To be fair, that's generally an impossible feet to deal with in this kind of situation, that's just to be expected. but these images seems appropriate to a double exposure shot-type of post processing. Just something to have in mind next time you shoot something like that. You may chose to keep it that way too, less of a pain in the rear and it is an aesthetic choice of your part.
Also, sorry to ear about your stolen gear. That really must hit where it hurt, good to see you went back on your feet.
