Essex Rivers Hub

Natural stretch on the whole but the Mill Race brings some artificialness to the channel and the presence o f a weir is also a possible barrier to fish. The channel is also very deep in places and is probably the result of dredging.

Algal blooms are developing so high nutrients in the water are obviously a problem here.

The area (land use)

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

No livestock were recorded.

Channel characteristics

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

At the time of recording the flow of water was Array and the channel was Array wide and Array in depth.

For most of this stretch the channel profile is steep.

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

Engineering

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

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

Wildlife

Signs of mink were seen during the survey.
