Weir [NAT]
OS 1:10,000 map, 1985.
This weir and footbridge span the River Clyde upstream of Bonnington Linn [name: NS 8834 4056] and control the supply of water to Bonnington Power Station (NS84SE 131.00). The river here forms the boundary between the parishes of Lesmahagow (to the S) and Lanark (to the N).
The location assigned to this record defines the midpoint of the structure. The available map evidence suggests that it extends from NS c. 88459 40700 to NS c. 88484 40660.

This tilting weir takes the place of a dam in a run of the river scheme. The weir is cleverly designed to self regulate by tilting so that the level of water diverted to the penstock intake balances with the compensation flow to the rest of the river. The Falls of Clyde scheme is an important example of the earliest large scale application of hydroelectric power for public supply in Scotland The scheme consist of two powerhouse each with an associated weir operating as run of the river schemes. All elements of the scheme are design cohesively in a modern classical style which was very influential over later developments such as the Rannoch / Tummel scheme.

Built during 1926 and commissioned in 1927 this is the second of two (see Bonnington) operating as run of the river schemes on the upper reaches of the River Clyde. The technical concept was designed by Edward McColl and the engineering specification produced by Buchan and Partners of Edinburgh. The civil engineering was undertaken by Sir William Arrol and Co. the powerhouse comprises two vertical shaft generators with Francis turbines connected to 11,000 volt turbines.
