A fast, boulder-lined wild-trout river north-west of New Norfolk, with bank starts at Maydena, Mount Field and Westerway, low-water nymphing and strict wading decisions.
The Tyenna is a fast wild-trout river about 20 km north-west of New Norfolk. It gives you pocket water and short boulder runs, with brown trout dominant and a reputation for rainbows as well. The fishing is close, physical and better suited to careful coverage than long casts.
Thick banks and a bed of large boulders divide the river into two practical choices. Where the bank is open, you can fish from dry ground and judge the current before committing. In the overgrown water, wading creates the casting room, but only when the river is clear and low enough to show each foothold.
For the simplest first look, choose Mount Field National Park. The bank can be fished there, and park passes are sold at the Mount Field visitor centre. The tradeoff is clear: pay the park fee and display the pass on your vehicle, leave bait behind and fish an artificial lure or fly.
Maydena and Westerway are the other bank-fishing starts. The ordinary all-method rule applies outside the park, but access across private ground still depends on signs or landholder permission. Begin from dry ground and nymph the nearest pockets before deciding whether to wade.
Summer and autumn usually give the simplest wading. As on any fast bush river, rain can push colour and extra water through. Check the Newbury flow before driving, and stay on the bank or leave when it rises. Never enter a flow you cannot read.
Bring a four or five weight, studded boots and a staff. Start with a weighted nymph, then switch to a dry only when fish show. The next decision is simple: read the current conditions, choose a legal bank start and fish upstream one pocket at a time.
