Carr Mill Dam

Carr Mill Dam is Merseyside, England's largest body of inland water, it offers picturesque lakeside trails and walks as well as national competitive powerboating and angling events.

Once simply a mill pond built to power Carr’s Mill, this was hugely expanded in the 1750s to provide water to the Sankey Navigation, (Sankey Canal), about a mile away. The lake is a firm favourite, busy with anglers and water sports enthusiasts. It’s also a great place for birdwatchers—herons, great crested grebes, coots, and various species of duck and gull can be found here.

The name Carr Mill traditionally came from the Norse word 'Carr' meaning marsh or fen. The dam is shown on the 17th century Yates map. A corn mill was operating there in the 19th century as it is visible on the first Ordnance survey map of the area, the dam having been doubled in size. There is no record of anyone named Carr having a mill there. The Land belonged to the Gerard family and a lease exists detailing the permissions and extent of use (St. Helens Archives). The dam was further enlarged by the London and North Western Railway during development of the railway system and cast iron marker posts are still visible at two points around the dam.

Carr Mill Dam can be accessed from the A580 road (East Lancashire Road) turn towards Billinge at the traffic lights. It is situated north of St Helens town centre, on the A571 (Carr Mill Road).
