The main river has a natural salmon population up to from the fjord, and salmon can also be found into the Svorka River, a tributary. After regulation of the river, salmon fishing has been limited to downstream from the Svorka power station. In 1986 salmon flukes, a parasite, were detected and the river was treated with

and the course of the river creates meanders. Upstream, from the Bjørnåssetra farm to the Brattset farm, the river runs through a relatively narrow canyon for a length of about . The watercourse was regulated in 1963 and it has several power stations along it, including the Svorka Power Station. Due to the regulation, water flow was reduced in two tributaries, the Svorka and Litlbævra (or Lille-Bøvra). Around 43% of the river's catchment area is used for the Svorka Power Station. Below the Svorka Power Station and from the fjord the total water flow is the same as before the regulation, but varies with the operation of the power plant and the water flow becomes very small when the power plant stops completely. The Nordsvorka Power Station came into operation in 2007. The water flow in the upper part of the river between the mouth of the Litlbævra and the Svorka Power Station has also been greatly reduced as a result of regulation. According to
