Overton Reservoirs 1–8 and Associated Channels is a complex of eight interconnected reservoirs built into the moorland landscape of Clyde Muirshiel Park in Renfrewshire, Scotland. The monuments sit upon Dinantian bedrock of mafic lava and tuff, creating a rugged, permeable foundation typical of the Mississippian volcanic geology that characterises much of this upland region. The construction exploits the natural topography to manage water flow across the plateau.
These reservoirs form part of the intensive water management infrastructure developed during the nineteenth century to support industrial activity in the Clyde valley below. The series of reservoirs and their associated channels represent a coordinated engineering system designed to store and regulate water supply, with each reservoir connected to allow controlled discharge downstream. The arrangement demonstrates Victorian hydraulic engineering adapted to moorland terrain.
The eight reservoirs remain visible features within the modern recreational landscape of the park, their earthworks and channel systems preserved as evidence of Scotland's industrial heritage. The site is protected as a scheduled monument under Historic Environment Scotland reference SM12810, recognising its historical significance as an example of large-scale water infrastructure from the industrial era.
