In 1810, William Jones and his business partner Ira Schofield, started construction on a new mill, a -storey, Georgian architecture style, stone mill, using an automated mill design by American inventor Oliver Evans. The mill was located on bedrock, north of Stevens' original mill, and the creek from the Upper Beverley lakes was diverted to this new mill. Abel Stevens' original dam likely raised the water in the original lower Upper Beverley Lake by about 4 to 5 feet (based on the appearance of the two Upper Beverley lakes on Grant's 1797 survey map of Bastard Township), the new stone mill, which acted in part as its own dam, with an adjacent bywash, raised the water level by about 9 feet (+/-), forming one lake where there had originally been two.
