high water levels. An attempt was made to reach a true right tributary below the dam, called Dam Creek, to estimate its flow and sample any fish populations. This proved impossible due to difficulties of access with the electric fishing gear. Another nearby tributary was visited by other members of the party, which was flowing at only a few litres per second. Negotiating the gorge from the upper end in winter proved difficult; it would be useful to understand what flows enter the gorge from its tributaries and obtain a more detailed understanding of the fisheries habitat in the gorge. Attempts to enter the gorge from the lower end also proved difficult due to high water levels.

In addition to the areas sampled, previous records from the area and the Freshwater Fisheries Database has been searched for any further fisheries data.
