PARRET or Padraz river, has its rise in the southern part of Somersetshire in England. Near Langport it is joined by the Ordred, augmented by the Ivel; and, about four miles from this junction, it is joined by the Tone or Thone, a pretty large river, rising among the hills in the western parts of this county. About two miles below the junction of the Tone, the Parret receives another considerable stream; and, thus augmented, it passes by the town of Bridgewater, and falls into the Bristol channel in Bridgewater-bay.
