Buttermilk Pond/Round Pond/Lily Pond trail

Both "My Trails" overlay and Google Earth Pro show a trail from Lily Pond to Round Pond and on to Buttermilk Pond. Has anyone ever hiked on those trails and are they passable most times of the year or do they get flooded? Are they an actual hiking trail or more of a herdpath?

Any experience on those trails would be welcome and appreciated.
