Sale Water Park is a area of countryside and parkland including a artificial lake in the Metropolitan Borough of Trafford in Greater Manchester, England. Opened in 1979 and owned by Trafford council, the water park lies in an area of the green belt running through the Mersey river valley between Sale and Stretford, located between the river and the M60 motorway. The lake was formed in the 1970s by the flooding of a gravel pit excavated to provide material for the construction of an embankment raising the motorway above the Mersey's floodplain. The pit was excavated to a depth of around , making the lake about deep in places.
