Essex Rivers Hub

Most of this section of the brook is concrete reinforced but some areas still have natural banks, also some areas have a stony bed allowing riffles to develop. The channel is quite shaded by trees with the best of the bankside vegetation to be found on the north bank, which is the Prittle Brook Greenway. The south bank is mainly housing so there is some problems with scrub development and rubbish. 

The area (land use)

The dominant land use for this stretch of river is suburban/urban.

No livestock were recorded.

Channel characteristics

The river channel consists of mainly silt, and riffles are present.

At the time of recording the flow of water was slow and the channel was <1m wide and <0.5m in depth.

For most of this stretch the channel profile is steep and bare.

Bankside trees were frequent, marginal plants and in-channel plants are abundant. Woody debris was noted to be occasional.

Engineering

The channel has been straightened and man-made enhancements are present along this stretch of river.

Field drains were recorded as absent and barriers / culverts are present.

Condition

Areas of trampling / poaching were absent and areas of erosion were absent at the time of the survey.

Wildlife

Species seen during the survey: Robin, Blackbird, Grey Squirrels, Speedwell, and Chervil.

Additional Information

The disused area on the south bank was of some concern as there is a risk that contaminants are present which could be entering the channel and affecting the water quality. This area is likely to be developed at some point in the future so urban drainage could then become s problem.

This section of the brook runs through an urbanised area so the brook flows under several roads.
