Extraction of silica sand occurred at the Congleton West Heath quarry from around the 1930s until 1984. The sand was used for making glass and for precision casting of metal. In September 1967, the Congleton Chronicle reported local opposition to further sand quarrying around Astbury, including complaints from residents about dust and arguments from footpath campaigners that diverted footpaths should be restored once quarrying ceased. After the closure of the quarry, the site was divided into housing (Ennerdale Drive estate) and open space. A trust was established in 1989 to manage the open land. The park first opened to the public in 1991. In 2002, the Stoke-on-Trent Angling Society acquired the lake. By 2008 the Astbury Mere Trust had acquired the majority of the land. The park was accredited by Natural England as a country park in 2012.
In 2004, the Court of Appeal decided Rhind v Astbury Water Park Ltd [2004] EWCA Civ 756, a personal injury claim arising from a diving incident at Astbury Mere, and dismissed the appeal. In reaching its decision, the court referred to Tomlinson v Congleton BC [2003] UKHL 47, which concerned Brereton Heath Country Park near Brereton, also in the Congleton area.
The park is located at around SJ846627 on Sandy Lane, off the A34 (Newcastle Road). The Fol Hollow road adjoins the park.

In 2022, a dog attack on a swan at Astbury Mere was reported, in response, the Stoke-on-Trent Angling Society installed security fencing. In 2026 the society began installing an expanded perimeter security fence around the lake, which some residents and the Astbury Mere Trust criticised as being installed without consultation. The society said the fencing was intended to protect swans and prevent wild swimming and related anti-social behaviour. The Trust also said that climbing plants on the fence line included an invasive species (Henry's honeysuckle).
Public Footpath No. 10 in the parish of Congleton (FP10) is part of the local public rights of way network administered by Cheshire East Council. In 2012, the council's Public Rights of Way Committee approved the diversion of part of FP10 under section 119 of the Highways Act 1980; the committee report described the affected section as terminating near Astbury Mere lake and recorded that the proposed new route followed an existing permissive path.
