It should, in fact, freshen up rivers and streams by cooling them down and maybe raising the level a little. Once the water temperature drops below about 15degC trout and trout food will go into autumn mode with mayflies hatching during the day and trout locking on to them. We are blessed with a plethora of riches in Otago and Southland as far as trout fishing is concerned, which makes choosing where to go the hardest decision of the day. We covered a lot of good water and saw no rises and between us we spooked four fish and landed two. I tied on a pair of damselfly nymphs, an olive one on the point and an orange version on the dropper.
