Howden Bridge weir is situated in the centre of Livingston and once supplied water to a nearby saw mill, now the site of a new housing development. A very basic construction of concrete covering rock infill, this weir was 40m wide and stands on the footprint of a structure which is thought to have been built in the mid 19th century.

The plan was to build a rock ramp. Large boulders were placed in front of the existing weir to create pools and a shallower incline for the migrating fish to find their way upstream. It is thought that this weir is currently the upper most limit to the salmon and sea trout migration on the Almond so improving this barrier will have opened up much more spawning habitat for these species. 

The rock ramp at Howden bridge was completed in the spring of 2019. The official opening of the project took place in September. The Howden rock ramp was Highly Commended in the coasts and waters category of the Nature of Scotland awards.
