 The lake is largely created by a steep boulder cascade with eastern embankments (close to small car parks at the side of Windsor Great Park, on London Road, Virginia Water which is the A30 road).The Chertsey Bourne flows through the north of the notable landscaped Wentworth Estate (residential 'golfside' mansions/large houses estate dating to periods since the 1920s) where a further weir creates the much smaller Wentworth Pond which is the lake of the Wentworth Club clubhouse.Before Wellington Bridge across the course, the Wentworth Brook rising in Sunningdale Golf Club joins.
