River Chelmer

A heavily modified but pleasant stretch of the Chelmer and Blackwater Navigation, running through predominantly arable land to the south of Boreham.

The area (land use)

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

No livestock were recorded.

Channel characteristics

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

At the time of recording the flow of water was slow and the channel was 5-10m wide and in depth.

For most of this stretch the channel profile is steep, canalised.

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


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.


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


Numerous birds and butterflies recorded at the time of the survey.

Additional comments

Cricket Bat Willow plantation along the bank. This area appears to suffer from nutrient enrichment due to dredging of the channel.
