Data DownloadCross 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 (991kb). (For details on using the data click here.)
Land Use / Management ChangesThis site is primarily to aid in estimating the influences of releases from upstream United Utilities works on downstream flows. Fences were erected to limit stocking to help maintaining upland habitats on the moors and mixed broadleaf trees have been planted.

Channel DescriptionThe 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.)
