Rivers Blackwater and Pant

This section of the river runs downstream from Clay Wood to meet the B1051 just south of Great Sampford. This is a meandering stretch of the river with little modification to the channel.

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 sluggish and the channel was 2-5m wide and 0.5-1m in depth.

For most of this stretch the channel profile is variable.

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


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 absent.


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


Dog’s Mercury was recorded in the upstream section and evidence of Badger and Hare activity was noted during the surevey.

Additional comments

Although some trampling and erosion was noted, this section has generally suffered fewer problems with erosion than the area upstream of Clay Wood. Some areas of pasture and woodland were noted, and a mix of mature, young and newly planted trees were present in this stretch.
