Flow Duration
Curve for Gauged Daily Flows

Station Description
Ultrasonic gauging station,
multi-path, cross configuration. Gaugings confirm calibration. In hot weather
the gauge can malfunction (due to temperature gradients in the measuring
section). No routine naturalisation - therefore d/s Kingston (39001) series is
more hydrologically representative).Catchment
Description
Scarp and vale topography developed on diverse geology.
Predominately rural headwaters contrast with considerable suburban growth in
the lower valley.River Flow and Catchment Rainfall

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.
