River Stort

The source of the River Stort is South-West of Saffron Walden, near Langley in Essex. It flows through Hertfordshire via Bishop’s Stortford where it is canalised before weaving across the Essex and Hertfordshire borders until it joins the River Lea.

A year of planning finally came to fruition when 188 water voles were released on the Herts and Middlesex Wildlife Trust reserve at Thorley Wash nature on the River Stort. This joint project between Essex Wildlife Trust and Herts and Middlesex Wildlife Trust is intended to kick-start a recolonisation of the catchment after 8 years of successful mink control failed to result in a return of a natural water vole population.

This project has allowed the successful restoration of 500m of river channel with 2000m2 of scrub being removed allowing for the same area of reedbed to be restored.

Following this work and with some additional ditching works, this site is now considered suitable to act as a receptor site for a water vole translocation and will be receiving animals in 2015.

The valley of the Pincey brook between Hatfield Broad Oak and Takeley is a wonderful example of a quiet rural valley and stream.

Essex Biodiversity Project identified Pincey Brook (south of Hatfield Forest to Hatfield Broad Oak) as one of a handful of areas in Essex which offered a site for a river restoration project.
