River Colne

This stretch of river flows through grazing pasture, grazed by sheep.

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 absent.

At the time of recording the flow of water was slow and the channel was 2-5m wide and in depth.

For most of this stretch the channel profile is steep/vertical undercut.

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


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 absent at the time of the survey.


Evidence of Greenfinch, Kestrel, Otter footprints, Skylark and Little Egret were recorded at the time of the survey.

Additional comments

The channel is quite overgrown throughout the summer; the water level is extremely low for the time of year – usually 0.5-1.0m in depth. There are eroded areas along the bank, possibly created by sheep using the river but no excessive poaching is visible at present.
