At a Glance
Arnold Station is in a region of high rainfall — it generates at high capacity all year, without need to control the level of Lake Brunner. A dam across the Arnold River maintains the water levels to power the station’s turbines.
Environment and recreation
Upstream of the dam, there’s an excellent recreational fishery, as well as recreational camping and walking areas. Downstream, the combined flow from generation, spillway gates and the remainder of the river supports a stable fishery. The river is also popular for kayaking.
At the dam, there’s an annual elver (young eel) trap and transfer programme. This aims to help boost numbers of Longfin Eel.
