It is {{convert|2|mi}} south-west of Gorleston-on-Sea, {{convert|5|mi|km}} north-west of Lowestoft and around {{convert|1.5|mi|km}} inland from the North Sea coast, in the parishes of Belton with Browston, Hopton-on-Sea and Lound. It is owned by Essex and Suffolk Water and managed by the Suffolk Wildlife Trust.{{cite web|url= http://www.suffolkwildlifetrust.org/reserves/lound-lakes |title= Lound Lakes |publisher= Suffolk Wildlife Trust |accessdate= 2 August 2017}}

The lakes were originally created as a result of peat digging in the medieval period. They consist of a number of reservoirs and feed into Fritton Decoy and then to the River Waveney to the west. They have a catchment area of {{convert|20|km2|mi2}}. The catchment is primarily arable land and this leads to nitrate runoff into the lakes, creating issues for water supply and habitat management.River Waveney, Fritton and Lound Lakes, Essex and Suffolk Water.
