Moelva (old spelling: Maa Elv) is a river in the municipalities of Birkenes and Lillesand in Agder, Norway. It originates from a hill south of Tveide in Birkenes and empties into the Tingsakerfjord, east of the town of Lillesand. Large parts of the disused, former railway Lillesand-Flaksvand Line followed the river bank.
An old stone bridge is still located by Helvetesfossen. It was restored by the Norwegian Public Roads Administration in 1993.[2]
Hydropower
The hydropower company Lillesand Elektrisitetsverk was started as a private company in 1916. There were dams in all tributaries to Moelva, dam at Helvetesfossen and pipeline down to the power station at Tingsaker, that had a turbine of 150 hp, a generator of 125 kW and an oil transformer of 7 kW. The power plant was sold and closed in 1970.[3]
Fishing
Moelva is a sea trout leader in the lower part. It is Lillesand municipality that has been responsible for both the preparation and clearing of the riverbed and built a threshold dam in the lower part of the river. The sea trout population has recovered after a decline due to pollution.[2]
