Cross section survey data, stage/discharge data (including manual measurements of stage) and time series of levels (not corrected for atmospheric pressure) may be downloaded here (1.3mb). (For details on using the data click here.)

Land Use / Management Changes

Low stocking levels are being maintained for habitat regeneration. The catchment does contain a small number grips in the headwaters (see map), but the terrain is thought to be too steep for blocking.

Channel Description

The channel cross-section at the instrument location is provided below. Datum is taken as the top of the diver access tube (red bar). Width is measured from the left-hand side bank when looking downstream, with locations to left of the diver tube taken as negative and those to the right positive.

Details from an MSc student project are available here. (Note, the information above takes precedence over the student report.)
