THE NATURAL HISTORY OF CORNWALL by WILLIAM BORLASE, Rector of Ludgvan and Author of Antiquities of Cornwall 1758
Lo, or Low River, in Kerrier.
This River rifes in the higheft Northern part of Wendron parifh, whence, in about five miles, it reaches the borough of Helfton; about a mile below which it forms a Lake, called the Lo Pool; the River giving rife to the Lake, and the Lake, as the moft remarkable part of the Water, giving the name to the River.(b)
(b) In Speed, and Camden’s maps, and Norden Page 22, this river is called Cober, a miftake (as I apprehend) for Lober; (that is, the bar of the Lo) a fandy pebbly bank, thrown up by the fea at the mouth of this river, and ferving as a dam to form the Lake.
(note: at this time the letter ‘s’ was written ‘f’ except when it occurs at the end of a word)
