Essex Rivers Hub

Remove weir, install woody debris and reduce impact of dredging

This section would benefit from improving/increasing in-channel habitats and this could be achieved by installing woody debris. This will change the flow of the water, which will eventually create a more natural shape to the channel.

By creating a mixture of fast and slow flows, this will help to create shallow and deeper areas within the channel, this will allow different species to thrive as the habitat niches available will be increased.

This area has been dredged in the past and this is something that should also be avoided unless absolutely necessary as this has created a channel that has been over widened and over deepened, this has resulted in the need for more inchannel habitats to be created so further dredging should be avoided.

There is also a weir in this section, this is a problem for fish as it prevents fish migrating upstream. This could impact on fish populations upstream of these barriers and also reduces the ability for fish to find better conditions if a pollution incidence occurs or food availablity decrease.

Poor

WFD overall status objective

To achieve Good ecological status by 2027

Project type

Improve/create habitats

Benefiting species and/or habitats

Creation of habitats within the channel will increase biodiversity. By reducing the effect of the weir this could improve fish populations.
