The reservoir is used to buffer the water levels in the River Fowey in the summer. The water is collected downstream for domestic drinking water at the Restormel treatment works.
In addition to watersports facilities, a 3.2-mile (5.1 km) circular path runs adjacent to the lake.
The lake has a resident population of brown trout and is regularly stocked with rainbow trout and blue trout.
