If the lakes offer tranquillity, the often thunderous torrents of the mighty Thredbo River in a spring defrost are a completely different prospect. A place where the fish jump and hide and race for rapids and waterfalls. This is fly fishing of another dimension. Previously known as the Crackenback it runs from Thredbo to Lake Jindabyne and is without question one of the most beautiful trout perfect rivers ever. Giant fish and trout over 10lb are a likely yield and its appeal is its accessibility. As one of the regions two only declared "trout spawning streams" the rule is one fish per angler per day (though it is possible to continue to "catch and release" and a minimum size of 50cm). And no bait fishing.
