The River Tarrant is one of England’s most productive brown trout locations.  It is the main spawning ground for salmon and trout in the middle reaches of the main River Stour.

The Tarrant, like many chalk streams, is ground fed and is a ‘winterbourne’ – it naturally dries up in summer.  Unnaturally, because of man-made in-stream structures such as weirs, the Tarrant dries up from the bottom – leaving fish stranded behind the structures.

Over many years the Environment Agency has rescued hundreds of stranded fish and moved them to the Stour. It will now fund a new detailed study to address the issues on the Tarrant.

The study, to be conducted by Wessex Rivers Trust, will include a desktop study of historic maps, hydrological data, LIDaR data, and underlying geology.

Fieldwork will include a topographic survey of the seven sites associated with fish entrapment, drawn up as long sections, cross sections and plan views.

There will be a round of stakeholder engagement and people will be able to view outline designs for each site. The findings and designs will be promoted in spring next year.

Environment Agency project manager Luke Kozak said: “This project will focus on the lower stretch of the River Tarrant. Here it dries out frequently in summer, leading to significant numbers of fish and invertebrates becoming trapped in pools as the river recedes.

“We have been carrying out fish rescues for the past 20 plus years to prevent the death of significant numbers of fish. Our data suggests that in 2003 some 2,800 salmonids were rescued from different areas of the River Tarrant and moved downstream to the main River Stour.

“The river is not only an important spawning tributary for salmonids, but also contains bullhead (Cottus gobio), a protected species under Annex II of the European Habitats Directive.”
