Yorkshire Dales Rivers Trust
Encyclopedia
The Yorkshire Dales Rivers Trust was formed in 2004 with a remit to improve, restore and conserve the river
River
A river is a natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river. In a few cases, a river simply flows into the ground or dries up completely before reaching another body of water. Small rivers may also be called by several other names, including...

England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west; the Irish Sea is to the north west, the Celtic Sea to the south west, with the North Sea to the east and the English Channel to the south separating it from continental...

The trust's remit is to improve the catchments of the four rivers of interest from the headwaters to the Humber Estuary, starting with the upland sections of the rivers before moving work downstream. Many of the impacts on rivers arise close to the headwaters where annual rainfall is high and topography

The trust works directly with the farming community to try to identify win-win situations that can both improve the condition of river ecology whilst reducing farming costs or saving time. A simple example of this is rerouting clean rain water from slurry

. The Association of Rivers Trusts has assisted with this work through the PINPOINT project which, through funding from the Catchment Sensitive Farming Delivery Initiative, has provided training in delivering farm advice.

Measures such as gill planting or blocking upland drainage channels have helped reduce impacts on rivers by slowing flow rates and decreasing sediment

This helps targeting of resources and allows river restoration to occur in the most needed locations.
