lies close to the River Biss and in the 19th century river baptisms took place with over 2000 in attendance; the bridge here is still called 'The Baptising'.
The river enters the centre of Trowbridge from the south-east through the Biss Meadows Country Park. For a semi-urban location, the country park has a rich variety of wildlife and includes areas of three UK
Biodiversity Action Plan priority habitats. Here the country park acts as a flood plain as well as an amenity space. Passing through Biss Meadows, it skirts round a pond (renovated in 2012 by the Friends), passes over a weir, skirts around the Tesco Extra car park (in 1993 the river was diverted here) and then flows under the County Way dual carriageway.

It then flows through the Town Park, where a small constituent lake is haunt to wildfowl, before passing behind shops and industrial buildings in a Riverside Walk which was opened in 1993 by the

. Before leaving the centre of Trowbridge, the Biss flows under the Town Bridge in roughly the location of the original river crossing which gives the town its name; in this area the river is home to the
yellow water lily known as "''Brandy Bottle''" after the shape of its fruit and its characteristic scent.

Although Trowbridge is a former woollen cloth manufacturing town, for which a supply of water was required, the Biss was never substantial enough to satisfy the demands of that industry. However, there was an attempt to supply the town; the Trowbridge Water Company was formed and piped water was turned on in the town on 30 September 1874. Supplies were inadequate, however, and the venture failed.
The company had premises in Waterworks Road, now a residential area.
On leaving the town centre, the Biss continues northwards through the Ladydown area. It is crossed by the
