Station Description
Ultrasonic gauging station -
multi-path (6) in cross configuration; transducers located in piles set in the
channel. Excellent agreement between multi-meter check gaugings and US
calibration. Levels affected by gate and lock movements. In hot weather
temperature gradients can deflect beams. Major PWS abstractions u/s.
Catchment Description
Scarp and vale
topography. Diverse geology. Predominantly rural headwaters contrast with
substantial urban and suburban development in the lower reaches.Factors Affecting Runoff
- Runoff reduced by
public water supply abstraction.
- Runoff influenced by groundwater
abstraction/recharge.
- Runoff reduced by industrial/agricultural abstraction.

For many stations monthly peak flows are also
archived. When daily flow data are not available monthly mean flows may be held
on the National River Flow Archive. See Data Holdings
