This station commenced operation at Wills Terrace cauBeway in February 1953. In April 1970 it was moved 200 metres upstream to the present site, retaining the same gauge datum. During the period of operation there have been 175 stream gaugings done. Before April 1970 the cease to flow gauge height was .838 metres. The largest discharge gauged was 233 m I/s on 5/2/67 at a gauge height of 2.170 metres. After April 1970 the largest discharge gauged was 450 ml/s on 5/3/72 at gauge height of 3.115 metres. The cease to flow gauge height is presently 1.2 metres. The highest recorded gauge heights before and after April 1970 are 2.719 and 3.225 metres respectively. There are 69 months of incomplete records~ Low stage control is the sandy river bed while at medium and high stages the control is Wills Terrace causeway~ 2.3.4 G.S. 006126 This section commenced operation in August 1959. There are 55 months with incomplete records. Control at the station is the Ross Highway causeway and the stable stream banks. 32 gaugings have been done with the highest discharge gauged being 145m l /s on 23/2/67 at a gauge height of 1.219 metres. The highest gauge height recorded is 1.950 metres. Cease to flow gauge height is O.Om. It should be noted that gaugings at this station have encountered recurring problems such as shifting bed levels and debris interference. Most of the higher ratings are thought to have underestimated discharges. 2. 3. 5 C.S. 006047 Records commence in 1958 and siIlce then there have been 64 months of incomplete records. 97 gaugings have been done, with the largest discharge being gauged at 52 ml/s on 5/3/72 at a gauge height of 2.347 metres. Highest recorded gauge height is 3.164 metres on 17/4/61. Cease to flow gauge height is 0.456 metres.
