Cod Beck Reservoir, Scarth Moor, Coast to Coast

Cod Beck Reservoir is one mile north of Osmotherley. There is ample parking available and attractive circuitous walks, making it a haven for easy and scenic walking. North west of the Reservoir is Scarth Wood Moor which is an SSSI, with many of its own attractions, e.g. there is an orthostatic wall and many burial cairns.

Cod Beck Reservoir is no longer used as a reservoir, but was in use as such from completion of its building in 1953 until closure of its treatment works in 2006, following a deterioration in the quality of the water, and the presence of cryptosporidium (crypto) which is a parasite that can cause respiratory and gastrointestinal illness and diarrhoea.

Cod Beck Reservoir


The lake and its surrounds are of importance to common toads that hibernate in the moorland. Brown trout, grayling, bullhead, eel, stone loach, minnow and lamprey populate the lake, and otters have been seen there.

Cod Beck Toads


Common toads abound on Scarth Wood Moor, and in the Cod Beck woodlands that encircle the Reservoir. The Moor is separated from the Reservoir by Quarry Lane, a minor road between Osmotherley and Scarth Nick. When the Toads are ready to spawn they need access to a lake or river and many have to negotiate Quarry Lane, resulting in a large number of toad deaths. Volunteers have been organised to help them across.

Common Toad Overwintering


Common toads overwinter (as opposed to hibernate) and on warmer days are still active. For most of the year they reside in the rough grasses of Scarth Wood Moor and Pamperdale Moor and in the Cod Beck Woodlands.

Cod Beck Woodlands


The Cod Beck Woodlands consist mostly of coniferous trees managed and maintained by the Forestry Commission. There are broadleaves around some of the woodland margins.

Otters at Cod Beck Reservoir


Otters are now common at Cod Beck and Cod Beck Reservoir. They feed on the well stocked lake fish, preferring eels, trout and chub. Crayfish also thrive in the Reservoir and add to the otter's diet.

Mute Swans at Cod Beck


Mute Swans are also known by their latin name Cygnus Olor, and they have a constellation named after them - Cygnus the Swan. Mute Swans are one of the heaviest flying birds in the UK. The male swan is known as a cob, the female as a pen and young birds as cygnets.
