SRA Annual Report 2020-21: Langport flow station

In 2019 the SRA Board approved an Environment Agency bid for funding for a permanent flow gauge in the River Parrett in Langport. In 2020, ground investigation works were completed and the flow station was designed. In 2021, it is due to be built.

Used in combination with data from existing gauges at Chiselborough, Yeovil, Donyatt and Stathe, information from the new Langport flow station will benefit approximately 770 square kilometres (478 square miles), that is the catchment area above Langport for the Parrett, Isle and Yeo rivers and all of their tributaries.

Getting better information will allow for earlier and more flexible operation of key control structures on the River Parrett, River Sowy and King’s Sedgemoor Drain. It will strengthen flood warning systems for local people and businesses, and help with the implementation of Water Level Management Plans. The Langport flow station will also complement the SRA’s forthcoming moves to increase the capacity of the River Sowy and King’s Sedgemoor Drain (read more about the River Sowy-King’s Sedgemoor Drain Enhancements Scheme in the SRA Annual Report 2020-21).
