Val de la Mare Reservoir is the private property of Jersey Water and is kept open for the enjoyment of the general public.

The reservoir was constructed in 1962 and is the second largest reservoir in Jersey (Queen’s Valley is the largest). The reservoir holds up to 938.7 megalitres of untreated water (enough to supply Jersey with water for approximately five weeks). Water feeds into the reservoir from its catchment area of 350 hectares (865 acres) which extends towards St Ouen’s Parish Hall in the North and La Grande Route de St Pierre in the East. Water is also pumped to Val de La Mare from the desalination plant when it is in operation.

The reservoir is fitted with underwater machinery designed to maintain the quality of the water in the reservoir. The equipment releases air bubbles into the water at predetermined intervals which helps to turn over and mix the water. If you see the water in the reservoir bubbling in certain locations this is what is happening.

There are several walking routes (click here) around Val de la Mare Reservoir, the full circuit is 2.8miles (4.5km).

The reservoir has a natural wealth of flora and fauna and is home to many species of birds and wildlife. Owls are also particularly encouraged at the reservoir – see if you can spot their nesting boxes.

We hope that you enjoy your walk around Val de la Mare Reservoir. For your own safety, the enjoyment of the reservoir by others and for hygiene reasons please follow the guidelines below.
