Long Term Goal

Under the European Water Framework Directive (WFD), most rivers, lakes, reservoirs, streams and canals need to be restored to good ecological health by 2021 or 2027. The Environment Agency monitors the health of rivers, lakes and canals and reports on their ecological health as part of its duties under the WFD.

A Healthy River

A healthy water body has thriving populations of fish, invertebrates, plants and diatoms (microscopic algae). They depend upon a healthy flow of water and a variety of natural habitats. All of these are affected by the levels of pollution and nutrients in the water, and the shape and structure of the water body.

How Healthy Is This Catchment?

Right now, all of the rivers, lakes and canals in the Brent Catchment are considered to be in either ‘poor’ or ‘moderate’ ecological health. This is because they are being affected by pollution from various sources and modifications that have been made to their
shape and structure.The latest information on the health of the eight water bodies in the Brent Catchment can be found on The Catchment Data Explorer website:
