If fishing the lake fish just before sun up into the dawn for margin feeders at spots such as curiosity rocks waste point poo bay and near the dam wall, kalkite another good area also do this into dusk and last light. Use rapala in xrap, j series and cd series in trout patterns and gold fish patterns. Another great spot is Island bend amd the snowy but if you fish the snowy stay on the left hand side of the river going upstream in case the let water go for hydro electric generation. Thredbo river is very productive work the banks and deep pools as well as the faster water. Lot of smaller fish at this time of year but there can be some big ones taken.
