Essex Rivers Hub

This is a natural section with shading, almost no instream vegetation, some nice marginal vegetation but generally coarse with frequent Himalayan Balsam.

The area (land use)

The dominant land use for this stretch of river is pasture.

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 medium and the channel was 2-5m wide and <0.5m / 0.5-1m in depth.

For most of this stretch the channel profile is steep.

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

Engineering

The channel has not been straightened and man-made enhancements are absent along this stretch of river.

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

Condition

Areas of trampling / poaching were present in the downstream section only and areas of erosion were absent at the time of the survey.

Wildlife

Banded demoiselle and yellow iris were noted on this section, along with the invasive himalayan balsam

Additional Comments

The river profile is uniform and was probably dredged in the past. Woody debris is found in several locations in this area creating great habitat. Road runoff may be impacting on water quality near to the road bridge. Downstream of this section is a broad channel with many wide meanders. Bordered by private land at the southern end. Grazed on the east bank and unmanaged scrub/woodland in the west bank.
