List of lakes of Wales

This is a list of lakes in Wales, including those created as reservoirs.

Except where otherwise referenced, all lakes listed here are named on the relevant Ordnance Survey map at 1:25000 scale.

This list of Welsh lakes ordered by principal areas (counties and county boroughs) includes lakes with a surface area of greater than 5 acres (2.0 ha), but excludes those lakes and ponds created as part of an active industrial site (i.e., works ponds) and also excludes service reservoirs used to store drinking water as part of the water supply system.

Grid references identify the approximate centre of the lake or the dam in the case of artificial reservoirs.
