In addition to the statutory designations at several of the lakes, many have areas set aside as Special Protection Zones or Nature Reserves. These areas are deemed internally as high quality conservation value and do not have any recreational activities taking place within them with the exception of footpaths for walkers.
The zones vary in size and composition, but the aim is to protect the valuable habitats and species within them.
