The extract shown here starts:

XXIX. THE LAND OF RALPH DE MORTIMER IN 'BUDDLESGATE' HUNDRED
RALPH de Mortimer holds OTTERBOURNE. Cypping held it of the bishopric of Winchester. He could not withdraw from the church. It was then, as now, assessed at 4 hides. There is land for 5 ploughs. In demesne is 1 plough; and 10 villans and 8 bordars with 2 ploughs. There is a church, and 6 slaves, and 50 acres of meadow, and a fishery rendering 2 shillings ; from the pasture, 10s. In the time of King Edward, it was worth 8 pounds ; and afterwards, as now, 100 shillings.

Botley is mentioned at the foot of the page and (inset) at the head of the next page):

The same Ralph holds BOTLEY. Cypping (Cheping) held it of King Edward. Then, as now, it was assessed at 2 hides. There is land for 6 ploughs. There are 8 villans and 4 bordars with 4 ploughs. There is a church, and 4 slaves, and 2 mills rendering 20 shillings , and 12 acres of meadow. There is no woodland. In the time of King Edward, it was worth 10 pounds ; and afterwards, as now, 100 shillings.

So Manor Farm Pond is, I suppose, implicitly mentioned as part of one of the two mills - the other of these, then, would be Botley Mill - which is approximately a mile to the north of Manor Farm, where the modern village of Botley has developed, although as the linked site mentions, there seems a fair deal of controversy and speculation about the original location and identity of all properties mentioned here.
