Cobbinshaw Reservoir feeds the Union Canal via the Bog Burn, Murieston Water, and through Mid Calder to the Almondell Aqueduct and Lin’s Mill Canal Feeder which feeds into the canal just east of the aqueduct.
The reservoir is also a a Site of Special Scientific Interest (SSSI) and is popular with wildfowl.
As part of our statutory obligations as reservoir owners, works are being undertaken to safeguard the integrity of the reservoir and manage risk to the wider public and downstream. The project will involve stopping the leakage through the spillway and along the downstream pipe route of the three siphons. The planned leakage repairs to the spillway are to protect this concrete structure from sub-surface erosion.
