The Fairwater Leat, fed by the springs at Rydon, superseded the Honeywell Spring as the established water supply in the Middle Ages and also supplied the power for three mills. A drought is said to have given rise to the annual Ram Roasting fair. According to legend there was insufficient water to baptise a child so a ram was sacrificed to the gods of the local spring. Water sprang forth and a ram has been roasted ever since at the fair, held nowadays on the late May bank holiday. Whit Tuesday was the traditional day for the fair but it was switched to Whit Monday in the early 1950s to fit in with school holidays and the later switch to the late May bank holiday was made for the same reason when the bank holiday was fixed as the last Monday in May.
