Langford lakes and the River Wylye are renowned for their popularity for angling but fish populations have declined over recent years. In an attempt to trap sediment and diversify flow, a number of natural materials have been introduced to the stream. Creation of a V weir.

It is therefore, too early to establish which are likely to provide answers in terms of best practice and whether the increase in channel diversity will have a long term benefit for fisheries objectives. Some concerns were raised during the site visit about the use of the v weir in this particular situation and it remains to be seen how successful/sustainable this will be compared to the more ‘natural’ diversity initiatives using on site materials over the longer term. The faggots and pegs appear already to have trapped some sediment behind them. They are, however, very experimental and their height, in this case (approx 40-50cm), may ultimately be most critical to their long term success. Nevertheless they may provide a possible alternative to places where toe boarding or similar structural support has been used along other rivers. This is an excellent site for viewing and discussing a range of techniques, and evaluating their effectiveness and suitability along chalk streams and elsewhere.
