Weirs and their impact on life in the river

Many rivers are failing to achieve good ecological status’ because they are fragmented into sections by weirs. It is not always obvious to most people why weirs are viewed as such a problem to fish and other wildlife in the river, especially as in many cases they have been there for a long time.

The two videos below explain the impact that weirs have on the way that the river functions and the impact on fish and all other wildlife in the river.
