I I I I I I I I I I I I I I I I I I I I 1985/86 COOPER WET SEASON REPORT WET SEASON OPERATIONS Field teams were engaged in an extensive gauging program in the Nabarlek area between January and late February on Cooper Creek and its major tributaries with a total of 97 flow measurements being performed. (Appendix 4) No high stage gaugings were pe~formed within the catchment during the entire period of field operations because the amount of rainfall was low during the wet season. However, valuable low to low medium discharges were obtained at all designated gauging sites. These data were used to further enhance the verification of the lower end of station rating curves. Similarly, gauging on the billabong inflow and outflow systems was impeded with, in the main, estimates of flow only being recorded. Comparatively few discharge measurements were made at GS821.000l (Nimbuwah) and GS821.0046 (Nimbuwah Tributary) due to difficult road access. Relatively light effort was put into gauging at GS821.0024 (Nabarlek) due to the perceived adequacy of its eXisting rating. The sediment transport study planned for Cooper Plains was cancelled due to the unseasonal weather conditions as was the intended high stage gauging program at GS82l.00l6 (Ht Borradaile). Two dye tracer studies were performed in the mixing upstream of GS821.0024 (Nabarlek) with 16 gaugings performed during the exercise. These studies have reported separately. zone being been The two supplementary stations at GS821.0051 (Buffalo Ck and GS821.0052 (Kadjirrikamarnda Ck) continued to be maintained on a weekly basis for the purpose of collecting stream height data and measuring discharge until the middle of Hay when the recorders were removed. This data was collected as part of the ongoing monitoring program of QHL's irrigation trial of EP2 water and will be reported on separately.
