Table : Flow monitoring along the Goulburn River. Reach Reach Relevant Hydrographic Stations Number Description Site ID Site Name Adequacy of Gauge (pers comm. Leon Tepper Thiess Tatura) – 1 Lake Eildon to 405203C Goulburn River @ There is an unstable Molesworth Eildon stage/discharge relationship at this site due to seasonal weed growth along the gauging station reach. This has most impact on flows of <1,000 ML/d. For flows between 1,000 and 4,000 ML/d the uncertainty is better than 8% at 95% confidence limit. 2 Molesworth to 405201B Goulburn River @ Likely issues with lower flows Seymour Trawool (<1,000 ML/d). The site relies on a natural channel control giving poor low flow sensitivity and a mildly unstable stage discharge relationship. Low flow gaugings are undertaken 2 km upstream of the site. 3 Seymour to 405202B Goulburn River @ The stage/discharge relationship is Nagambie Seymour stable. Flow data uncertainty is better than 4% at 95% confidence level. 4 Goulburn Weir 405259A Goulburn River @ Flood measurement only >3.5 m. to Shepparton Goulburn Weir Upon request only. 405200A Goulburn River @ The conventional method of Murchison monitoring flow using a stage discharge relationship is not adequate for this site. The site is subject to hysteresis, different types of loop rating curves occur
