Essex Rivers Hub

Remove weirs so that the mill race and main channel have better connectivity

There are two weirs either end of the mill race which control the flow between this channel and the main channel, if these were removed or reduced then the connectivity between the two channels would be improved and create a more natural  habitat in the mill race.

On the day of the survey the mill race had a high water level but a static flow where as the main channel had a low water level but a faster flow.

The weirs will also be acting as a barrier preventing species moving between the two channels, and moving further upstream.
