The second jewel of the Trøndelag salmon belt — shorter than the Gaula but equally productive and with a strong fly culture. Black & Orange is a personal favourite on the Orkla among experienced anglers. Multi-sea-winter salmon with excellent grilse runs. Mix of private and public beats. June–August season with mid-summer often strongest. Equipment disinfection mandatory.
The Orkla falls roughly 1,058 m over 179 km from Lake Orkelsjøen high in the Oppdal mountains to Orkdalsfjorden at Orkanger, giving an average gradient near 0.6% — similar slope to the Gaula but a very different river because the Orkla is heavily regulated. Five power-generation reservoirs built between 1978 and 1985 control the upper 39% of the catchment, suppressing winter-spring spates and buffering summer flow at a stable 60–70 m³/s while holding water temperatures down around 4–5 °C at the dam outflow and rarely above 15 °C in the main stem. The upper river is a partly-confined step-pool and pocket-water reach on Caledonian metasediment boulder and cobble; the roughly 88 km of anadromous salmon water above Orkanger settles into an unconfined pool-riffle reach on medium gravel and cobble with the flow-regulation signature of a stable, predictable bed — very different from the wild freestone Gaula next door.
