Fishing Arm River above the Mersey: the full guide

The Arm River above the Mersey

The Arm River runs off the high country near the Walls of Jerusalem through forest to the Mersey below Lake Rowallan; the gauge sits just above the junction. The Bureau of Meteorology’s gauge there supplies the level of the Arm River above the Mersey and the 30-day chart on this page. Lake Rowallan and Lake Parangana have their own pages.

Species and seasons

Brown trout are the fish of the Arm River, in the pools and runs on the fly and small lures. The general river rules apply: open from the first Saturday of August to the Sunday nearest 30 April, computed on the species card; where the river runs inside a national park or the World Heritage Area, the Code bans bait, so fish lures or fly there.

Where to fish it

The Mersey Forest Road and the tracks off it give access to the Arm; it is steep forest country, walked and waded.

Planning a visit

Mole Creek and Deloraine are the nearest towns with supplies. The Walls of Jerusalem National Park above it has no road access and is explored on foot.

The river through the year

The Arm River comes off the high country around the Walls of Jerusalem, where snow lies through the winter, so its flow rises with the thaw and the spring rain and runs cold well into the season. Early in the season, from August, the river is high, cold and hard to fish, and the trout lie deep; from late spring the water warms and falls, and the trout move into the runs and rise to the hatches. Summer is the best time, when the water is lower and clearer, and the fish are wild and wary in clear water. The forest country around it is steep and wet, and the tracks can be slippery after rain. A light rod, a few dry flies and nymphs, and a map of the access tracks are the kit for it.

Reading this report here

The chart shows the Arm rising after rain in the high country. The water temperature estimate, labelled as one, is cold at the August opening and cool from October; pressure and sky build the score on the Arm River.

Licence, access and rules

On the Arm River above the Mersey a Tasmanian inland angling licence is needed from age 14; our Tasmania licence page has the fees. The Inland Fishing Code, which sets the rules on the Arm River above the Mersey, is in the sources.

How this page was made. The daily report is computed by our scoring engine from live readings; nobody types it. The written text was drafted with AI assistance from the official pages listed above, and its facts were checked against those pages by automated verification on 27 September 2026; anything that could not be verified was taken out. Pablo Ruiz Quintero sets every guideline, the data-verification system and the minimum standards a page must meet to be published, reviews page structure and approves what goes live; the responsibility is his, and the AI carries out the work. We work this way because it is how one person can keep every page current with named sources. Not yet reviewed by an Australian angler or editor. Errors are published in the verification log; the full policy is in the editorial policy.
