If you are salmon fishing in Scotland in the upcoming days, using bigger flies coupled with sinking lines could be the order of the day. With the recent big lift in river levels and the drop in water temperatures, these tactics could prove to be productive. When the water comes up at this time of year, bigger flies show up well and they also seem to trigger an aggressive response from the salmon. When the water temperature drops, the fish are more likely to be lying deeper in the water column. This means that you should be adopting similar salmon fishing tactics to those during the spring. Allow the fly to sink and make sure that it moves slowly through the water. This could be your passport to success during the autumn months!
